After an unusually warm September and a rather balmy start to October, it finally felt like autumn in New York City this weekend.
According to the NWS, the temperature in Central Park only made it to 55°F on Saturday and 58°F on Sunday. The overnight lows were also rather chilly in the mid-40s. This was the coldest weather the city has seen since last spring. Its rather sudden arrival was a bit a jolt for many New Yorkers who had to scramble to find their jackets and sweaters that had been tucked away for months.

The calendar says October, but it still feels like summer in New York City.
The temperature in Central Park soared to an unusually balmy 80°F on Wednesday. While this did not break any records, the overnight low did. The mercury only dropped to 71°F, setting a new record warm minimum temperature for the date. The previous record of 69°F had been in place since 1949.
It is also interesting to note that Wednesday’s low was warmer than the date’s normal high. The city’s average high and low temperatures for this time of year are 66°F and 52°F, respectively.

September 2018 was another temperature roller coaster in New York City. Highs ranged from an unseasonably cool 62°F to a sizzling 93°F. However, with fifteen days posting above average temperatures, including three with readings in the 90s, the heat won out in the end. This warm finish was also aided by the unusually balmy overnight lows that were seen throughout most of the month. In fact, on September 5, the low only dropped to 77°F. That tied the record high minimum temperature for the date, which was set in 1985. In the end, the city’s mean temperature for the month was 70.7F°, which is 2.7°F above average.
In terms of precipitation, September was a soggy month in the Big Apple. In all, 6.19 inches of rain was measured in Central Park. Of this impressive total, 51% fell on just two days, each of which saw flash flooding around the five-boros. The city, on average, gets 4.28 inches of rain for the entire month.
Climate Week NYC begins on Monday. This annual global summit takes place alongside the UN General Assembly and brings together leaders from a variety of sectors, including government, business, and non-profit organizations, to discuss solutions to climate change.
Organized by The Climate Group since 2009, the goal of the conference is to keep this pressing issue high on the global agenda. This year, which marks the halfway point between the passage of the Paris Climate Agreement in 2015 and the 2020 target for countries to ratchet up their greenhouse gas cutting commitments, the event will focus on ways to accelerate climate action. The ultimate goal of the non-binding Paris Accord is to limit global warming to 2°C (3.6°F) above pre-industrial levels
Public events to raise awareness and support of the summit’s mission are scheduled all week around the city, from September 24-30. They range in style from panel discussions and seminars to concerts and exhibitions. For the full program of events, go to the Climate Week website.
The remnants of Hurricane Florence swept through New York City on Tuesday. While significantly weaker when compared to its time over the Carolinas, the storm still made its presence known with strong thunderstorms and bands of torrential downpours.
According to the NWS, 1.19 inches of rain was measured in Central Park. As impressive as that total is, it did not break the daily rainfall record for the date. That honor belongs to September 18, 1936 when 3.92 inches of rain was reported. New York City, on average, gets 4.28 inches of rain for the entire month of September.
The heavy rain caused flash flooding on roadways and disrupted travel across the city. Impacts were also felt underground as torrents of water poured into several subway stations through leaks in the ceiling and down the entrance/exit steps. Even the city’s infamous rats were seen sheltering from the rushing water.
This type of heavy rain event, according to NOAA, is expected to become more common as global temperatures continue to rise.

August 2018 was a hot month in New York City. It produced two separate heat waves and a total of seven days with readings in the 90s. Overnight lows were also mostly warmer than normal. In the end, the city’s mean temperature for the month was 78.1°F, which is 2.9°F above average. That means August 2018 is now tied with August 1955 as the city’s ninth warmest August on record.
August was also an over-achiever in terms of precipitation. In all, a whopping 8.59 inches of rain was measured in Central Park. That marks the city’s wettest August in seven years. Of this impressive total, 2.90 inches fell on a single day (August 11), setting a new daily rainfall record for the date. The city, on average, gets 4.44 inches of rain for the entire month.

The third heat wave of the summer baked the Big Apple this week.
The threshold for what constitutes a heat wave varies by region, but here in the New York City area it is defined as three consecutive days with temperatures reaching 90°F or higher. This week, the mercury in Central Park reached 94°F on Tuesday, 92°F on Wednesday, and 90°F on Thursday. With the dew point temperature in the 70s, it felt even hotter.
There was also little relief from the heat at night. All three dates tied or set new record warm low readings. The temperature only dropped to 79°F on Tuesday, 81°F on Wednesday, and 78°F on Thursday. The previous record high minimum temperature for all three dates was 78°F.
The main driver of this dramatic heat and humidity was a dominant Bermuda High, a large area of high pressure situated off the east coast. Spinning clockwise, it steered hot, humid air from the Gulf of Mexico toward the northeast.

August has only just begun and it is already New York City’s wettest August in seven years. This is largely due to the strong thunderstorms that swept through the city on Saturday and unleashed more than half a month’s worth of rain in just a few hours.
According to the NWS, 2.9 inches of rain was measured in Central Park, setting a new record for the date. The previous record of 2.39 inches had been in place since 1983. On average, the Big Apple gets 4.44 inches of rain for the entire month of August.
The torrential rain, which came on the heels of NYC’s wettest July in fourteen years, flooded roadways and caused power outages across the city. Significant delays and cancellations were also reported at the area’s airports.
This type of heavy rain event, according to NOAA, is expected to become more common in the northeast as global temperatures continue to rise and precipitation patterns change.

New York City is sweltering through its second heat wave of the summer.
The threshold for what constitutes a heat wave varies by region, but here in the NYC area it is defined as three consecutive days with temperatures reaching 90°F or higher. Wednesday marked the city’s fourth day of scorching conditions.
With the dew point temperature in the 70s, it felt even hotter. The heat index – the so-called real feel temperature – reached into the triple digits.
The main driver of this dramatic heat and humidity is a dominant Bermuda High, a large area of high pressure situated off the east coast. Spinning clockwise, it has been steering hot, humid air from the Gulf of Mexico toward the northeast.
While these conditions are oppressive, they can also be dangerous. The NWS issued both heat advisories and air quality alerts for the city over the past few days.

A tornado barreled through the New York City borough of Queens on Thursday night as powerful thunderstorms moved through the area. With winds between 70 and 85 mph, it was rated EF-0 on the Enhanced Fujita scale.
According the NWS, the twister touched down in College Point, Queens and traveled 0.7 miles east before dissipating in the Melba neighborhood. Measuring 100 yards wide, it knocked down at least 50 trees and numerous power lines. It also pulled the siding off several homes. No fatalities have been reported.
Tornadoes, historically, have been rare in New York City. In recent years, however, they have been happening more frequently. This latest twister was the 7th to hit NYC since 2010 and the 14th since 1950, when the NWS began tracking these destructive storms.
