This will be a summer to remember with weather that can be described as "wacky."

What You Need To Know

  • Summer 2021 was the second-wettest on record

  • 17 days had temperatures at 90 degrees or higher

  • July and August were some of the wettest months on record

You may be asking yourself, "wait, summer isn't over yet, how can you be doing a recap?" For meteorological records, summer is defined as the months of June, July and August. So, fall began September 1.  

This summer brought many rainy days, making it one of the wettest on record.

Steamy summer temperatures

Not only was the rainfall above average, but the temperatures were, too.

The city averages 15 days per year at 90 degrees or higher. 17 days this summer, the city hit 90 degrees or higher. That is above the average, and the city could still hit 90 degrees once or twice in September. 

What made this summer particularly noticeable were the heat waves. A heat wave occurs when three days in a row reach 90 degrees or warmer. The city had three heat waves. Two of those happened in June and one in August.

Overall, the month of June was the hottest month of the summer with eight days above 90 degrees, including one day that hit 98 degrees. July had four 90-degree days and August had five.

In between the hot months of June and August, July averaged cooler than normal. 

Dry start, then awfully wet

The summer ended up being the second-wettest on record. The city recorded 24.25 inches of rain. Interestingly enough, the month of June was dry with only 2.62 inches over the entire month. This is nearly two inches below normal. 

That all changed in July and August. Over 11 inches fell in July and over 10 inches fell in August. July was the third-wettest on record and August was the fourth-wettest on record. 

Ida's rain

If you're amused by "what if" situations, here's a good one for you. If Ida's moisture had arrived in the city just one day earlier on Aug. 31 rather than Sept. 1, it would've been included in the summer rain total for NYC. That seven-inch total in Central Park on Sept. 1 would've pushed the city to the wettest summer on record. If only 24 hours earlier!
