Spring Preview Brings NYC Warmest February Day Ever Recorded

The calendar says February, but it felt more like May in New York City on Wednesday. The temperature in Central Park soared to 78°F, setting not only a new record high for the date but marked the warmest February day ever recorded in the Big Apple.

Records are usually broken by fractions of a degree, but these were shattered. According to the NWS, the previous daily record, which was set in 1930, was 68°F and the former record monthly high that had been in place since February 24, 1985, was of 75°F. The city’s normal high this time of year is 43°F.

The primary driver of these unusually balmy conditions is a strong Bermuda High off the east coast of the US. Spinning clockwise, it is funneling warm southern air into the region.

Venturing out without coats and enjoying lunch alfresco, many New Yorkers took full advantage of this early spring preview. Personally, however, it felt a little surreal. February is typically the snowiest month of the year in NYC – a time when sledding and ice-skating are more common than ice-cream trucks and frisbees.

That said, these spring-like conditions will be short-lived. Temperatures are expected to return to more seasonable levels tomorrow. Get ready for weather whiplash!

January 2018: Earth’s Fifth Warmest on Record

Our global temperature continued its upward trend last month with January 2018 marking the fifth warmest January ever recorded on this planet. The last four Januarys now rank among the five warmest on record.

According to a report by NOAA’s National Centers for Environmental Information, Earth’s combined average temperature for the month – over both land and sea surfaces – was 54.88°F. That is 1.28°F above the 20th-century average. January was also the 397th consecutive month with a global temperature above its long-term norm. That means the last time any month posted a below average reading was December 1984.

While heat dominated most of the planet this January, some places were particularly warm, including the western half of the United States and most of Europe. For the contiguous US as a whole, January ranked among warmest third of the nation’s 124-year period of record.

Coming on the heels of 2017 – Earth’s third warmest year on record and warmest year without an El Niño – these soaring temperatures are largely attributed to the long-term trend of human-caused climate change. In fact, La Niña conditions – the cool counterpart of El Niño – were present in the Pacific during January.

2017: Third Warmest Year on Record for Planet and the Warmest Year Without an El Niño

It is official, 2017 was the third warmest year ever recorded on this planet. Only 2015 and 2016 were warmer.

According to a report by NOAA’s National Centers for Environmental Information, Earth’s combined average temperature for the year – over both land and sea surfaces – was 58.51°F. That is a staggering 1.51°F above the 20th-century average.

2017 also marked the 41st consecutive year with a global temperature above its long-term norm. That means the last time any year posted a below average reading was 1976.

While heat dominated the planet last year, some places were particularly warm. Here in the contiguous US, it was our third warmest year on record.

The exceptional warmth of 2017 is largely attributed to the long-term trend of human-caused climate change. While El Niño conditions helped influence record heat in the past, 2017 was the warmest year on record without an El Niño being present in the Pacific. In fact, ENSO neutral conditions prevailed for most of the year and La Niña – the cool counterpart of El Niño – developed in the autumn.

Looking at the bigger picture, nine of the ten warmest years on record have occurred since the beginning of the 21st century. Three of those years – 2014, 2015, and 2016 – were back-to-back record breakers. As greenhouse gases – the main drivers of global warming – continue to spew into the atmosphere, temperatures will continue to rise and records will likely continue to fall.

2017: Third Warmest Year on Record in US

2017 was the third-warmest year ever recorded in the continental United States. Only 2012 and 2016 were warmer.

The average annual temperature of the lower 48 states, according to a report by NOAA’s National Centers of Environmental Information, was 54.6°F. That is 2.6°F above the 20th-century average. 2017 also marked the 21st consecutive year that the annual average temperature for the contiguous US was above its long-term norm. That means the last time the US had a normal to below normal annual temperature was 1996.

From coast to coast, for the third year in a row, every state posted an above-average annual temperature. Five states – Arizona, Georgia, New Mexico, North Carolina, and South Carolina – had their warmest year on record. This was despite the unusually cold conditions that dominated the eastern part of the country in December.

The year was also notable for its unusual number of weather and climate disasters that each totaled more than $1 billion in damages. In all, sixteen such events collectively caused $306 billion in direct costs – a new US record. Sadly, they also claimed the lives of at least 362 people across the country. These incidents included drought, wildfire, floods, severe storms, and three major landfalling hurricanes.

The exceptional warmth of 2017 was independent of El Niño. In fact, ENSO neutral conditions prevailed for most of the year and La Niña – the cool counterpart of El Niño – developed in the autumn.

2017 Ties for 10th Warmest Year on Record in NYC

New York City experienced some noteworthy weather in 2017, especially the swings between record cold and record heat. However, the warmth won out in the end. The city’s average temperature for the year in Central Park was 56.3°F, which is 1.3°F above normal. That means 2017 tied 2001 for NYC’s tenth warmest year on record!

At the beginning of the year, the city experienced its sixth warmest winter ever recorded, including a record warm February. The temperature on February 24 hit 70°F – marking the first time the city has seen that type of heat in February in twenty years.

Spring was also unusually mild. It included the city’s second warmest April and second warmest Easter on record. It also produced an early heat wave in May.

The summer brought the city a number of oppressively hot and humid days, including thirteen days with temperatures in the 90s. The hottest day came on July 20 when the mercury soared to 94°F. When humidity was factored in, the heat index or real feel temperature was in the triple digits.

Autumn ranked as the city’s fourth warmest on record. It was highlighted by a record warm October.

The end of 2017, on the other hand, was marked by an extended arctic blast that produced the coldest readings of the year. On December 28, the high temperature only made it to 18°F and on December 31 the low was a bone-chilling 9°F – the second coldest New Year’s Eve in NYC history.

Precipitation for the year was somewhat erratic. Despite a few heavy rain events, including some that broke daily rainfall records such as the 3.02 inches that fell on May 5, the city was mostly dry. In fact, only four months of 2017 produced average to above average rainfall. Overall, NYC received 45.04 inches of rain in Central Park for the entire year. That is 4.9 inches below normal. This dearth of rain, according to the US Drought Monitor, caused abnormally dry to moderate drought conditions across the city for part of the year.

Snowfall, despite the warm winter, was abundant. During the year’s few arctic outbreaks, enough moisture was also in place to produce snow. For the calendar year as a whole, the city accumulated 34.7 inches of snow, which is 8.9 inches above average.

Planet Posts Fifth Warmest November and Fourth Warmest Autumn on Record

Our global temperature continued its upward trend last month. November 2017 tied November 2016 as the fifth warmest November on record and closed out the planet’s fourth warmest September to November period, which is known as meteorological autumn in the northern hemisphere.

According to the State of the Climate report by NOAA’s National Centers for Environmental Information, Earth’s combined average temperature for November – over both land and sea surfaces – was 56.55°F, which is 1.35°F above the 20th-century average. November also marked the 395th consecutive month with a global temperature above its long-term norm. That means the last time any month posted a below average reading was December 1984.

The three-month period of September, October, and November was also unusually warm. NOAA reports that Earth’s average temperature for the season was 1.35°F above the 20th century average of 57.1°F. That makes it the fourth warmest such period on record.

While heat dominated most of the planet this season, some places were particularly warm, including parts of southern North America and southern Asia. For the contiguous US as a whole, it was our tenth warmest autumn on record.

These soaring temperatures are largely attributed to the long-term trend of human-caused climate change. In fact, a weak La Niña – the cool counterpart of El Niño – developed in the tropical Pacific during October and prevailed in November.

Year to date, the first eleven months of 2017 were the third warmest such period of any year on record. With only one month left, 2017 is expected to end up among the top three warmest years ever recorded on this planet and become the warmest year without an El Niño. Global temperature records date back to 1880.

Autumn 2017: Fourth Warmest in NYC

The winter solstice is still a few weeks away, but meteorological Fall (September, October, and November) has officially ended and it was the fourth warmest on record in New York City.

The season, a transitional period between summer and winter, can often feel like a temperature roller coaster. This year, highs ranged from 91°F to 38°F. In the end, though, the warmth came out on top. The city’s average temperature for the three months was 60.4°F, which is 2.9°F above normal.

In all, fifty-nine days posted above-average readings and two of the season’s three months were warmer than their long-term norms. In fact, October 2017 was the city’s warmest October on record.  

This autumn was dominated by a pattern of warm spells separated by a few short-lived blasts of cold air. It was largely driven by the jet stream staying well to the north for most of the season with just a few dips southward.

The city’s warmest autumn on record, according to the NWS, occurred in 2015, which tied 1931 with an average temperature 61.8°F.  The coldest was 1871 when the three-month average was only  51.7°F.  Central Park weather records date back to 1869.

October 2017: Earth’s Fourth Warmest on Record

Our global temperature continued its upward trend last month with October 2017 tying October 2003 as the fourth warmest October ever recorded on this planet. Only October 2014, 2015, and 2016 were warmer.

According to the State of the Climate Report by NOAA’s National Centers for Environmental Information, Earth’s combined average temperature for the month – over both land and sea surfaces – was 58.41°F. That is 1.31°F above the 20th-century average. October was also the 394th consecutive month with a global temperature above its long-term norm. That means the last time any month posted a below average reading was December 1984.

It is also interesting to note that the ten warmest Octobers on record have all occurred in the 21st century.

While heat dominated most of the planet last month, some places were particularly warm, including much of Europe, northern Russia, and the northeastern United States. For the contiguous US as a whole, the month ranked among the warmest third of the historical record.

These soaring temperatures are largely attributed to the long-term trend of human-caused climate change. In fact, a weak La Niña – the cool counterpart of El Niño – developed in the tropical Pacific during October.

Year to date, the first ten months of 2017 were the third warmest such period of any year on record. With only two months left, 2017 is expected to end up among the top three warmest years ever recorded on this planet. Global temperature records date back to 1880.

October 2017: Warmest on Record in NYC

October 2017 was New York City’s warmest October on record. Its average temperature of 64.1°F was a staggering 7.2°F above the long-term norm. The previous record of 63.6°F was set in 1947 and tied in 2007.

Overall, twenty-six out thirty-one days were warmer than normal. Four of those produced readings in the 80s. Two record warm minimum temperatures were also set during the month. On October 8 and 9, the Big Apple only cooled down to 72°F and 71°F respectively. The average low for those dates is 52°F.

In terms of precipitation, the city was mostly dry. The weather station in Central Park reported 4.18 inches of rain, which is 0.22 inches below average. Of this total, 3.03 inches fell in a single day at the end of the month. This type of heavy rain event, according to NOAA, is expected to become more common in the northeast as the average global temperature increases and precipitation patterns change.

September 2017: Earth’s Fourth Warmest on Record

Our global temperature continued its upward trend last month with September 2017 marking the fourth warmest September ever recorded on this planet. Only September 2014, 2015, and 2016 were warmer.

According to the State of the Climate Report by NOAA’s National Centers for Environmental Information, Earth’s combined average temperature for the month – over both land and sea surfaces – was 60.4°F. That is 1.4°F above the 20th-century average. September was also the 393rd consecutive month with a global temperature above its long-term norm. That means the last time any month posted a below average reading was December 1984.

While heat dominated most of the planet in September, some places were particularly warm, including much of Canada and parts of Asia. For the contiguous US, the month ranked among the warmest third of the historical record.

These soaring temperatures are largely attributed to the long-term trend of human-caused climate change. ENSO-neutral conditions prevailed in September, which means there was neither an El Niño nor a La Niña to influence global weather patterns.

Year to date, the first nine months of 2017 were the second warmest such period of any year on record. Global temperature records date back to 1880.
