NEW YORK, New York — Step outside right now in the Northeast and you would never guess it is still spring.
Temperatures are surging toward the mid-90s across the East Coast, and more than 32 million people are already under heat alerts stretching from Philadelphia all the way up through New York City, Providence and Boston.
For many cities along the I-95 corridor, these are the first heat alerts of the entire year — and they are arriving in May.
Records That Have Stood for Decades Are Now in Danger
This is not just uncomfortable weather. It is the kind of heat that rewrites the history books.
New York City and Philadelphia are both under a Heat Advisory this May for the first time since 2022.
But it could get more serious than that.
If an Extreme Heat Warning is issued, it would mark the first time since May 2012 that both cities have been placed under one at the same time.
The numbers behind that possibility are striking.
New York City is forecast to hit 90 degrees or higher Monday through Wednesday — three consecutive days above 90 in May. The last time that happened was May 29 to 31, 1987.
That is a record that has stood for nearly 40 years.
What the Nights Are Telling You
The daytime heat is only part of the story.
In New York City, overnight lows are expected to stay between the mid-70s and 80 degrees. In Philadelphia, the overnight low is forecast to hover near 70.
Those are numbers that belong in late July, not mid-May.
When nights stay that warm, the body never fully recovers from the heat of the day — and that is when heat becomes genuinely dangerous, especially for the elderly, children and anyone without air conditioning.
Four Straight Days of Summer in Spring
Washington D.C. and Philadelphia have only hit 80 degrees twice so far this May. New York City has managed it just once.
That is all about to change.
All three cities, along with Baltimore, are now staring down up to four consecutive days in the 80s and 90s stretching into Wednesday — meeting the official definition of a heat wave: three or more consecutive days at or above 90 degrees.
This will likely be the first official heat wave of the season across the entire Northeast.
When Does It End?
The good news is that this heat will not last.
By the end of the week, a cold front is set to sweep through and drag temperatures back down into the comfortable 60s and 70s.
Summer is making a dramatic early cameo — but spring is not finished yet.
Until that front arrives, stay hydrated, check on elderly neighbors, limit time outdoors during peak afternoon hours, and find air-conditioned spaces if your home does not have cooling.
The record books may be getting rewritten this week — make sure you are staying safe while it happens.
