Heat Advisory: Muggy With Storms As Temps Climb Through Thursday

Get ready for steamy air, unforgiving heat, and scattered thunderstorms through tomorrow evening.

The National Weather Service has issued a Heat Advisory for New York City until 6pm on Thursday, July 13. A Heat Advisory is issued when the combination of heat and humidity makes it feel like 95–99 degrees for two or more consecutive days or 100–104 degrees for any length of time.

NYC temperatures are expected to climb to the upper 80s on Wednesday and low 90s on Thursday, but the high humidity and stagnant air will make it feel much hotter — teetering beyond discomfort and into potential health risks.

Then on Friday, forecasters predict a steep drop back to the 70s with heavy rainfall.

But until then, take precautions and look out for your neighbors by following these steps from NYC.gov:

• If possible, stay out of the sun. When in the sun, wear sunscreen (at least SPF 15) and a hat to protect your face and head.

• Use an air conditioner if you have one. Set the thermostat no lower than 78 degrees.

• If you do not have an air conditioner, keep rooms well-ventilated with open windows and fans.

• Consider going to a public pool, air-conditioned store, mall, movie theater, or cooling center.

• Fans work best at night when they can bring in cooler air from outside.

• Make a special effort to check on your neighbors during a heat wave, especially if they are seniors, young children, and people with special needs. Many older New Yorkers live alone and could suffer unnecessarily in the heat because they are isolated from friends and family.

• Drink fluids – particularly water – even if you do not feel thirsty. Avoid beverages containing alcohol, caffeine, or high amounts of sugar.

• Wear lightweight, light-colored, loose clothing that covers as much of your skin as possible.

• Never leave children, pets, or those who require special care in a parked car during periods of intense summer heat.

• Avoid strenuous activity, especially during the sun’s peak hours – 11am to 4pm. If you must engage in strenuous activity, do it during the coolest part of the day, usually in the morning between 4am and 7am.

• Cool showers or baths may be helpful, but avoid extreme temperature changes. Never take a shower immediately after becoming overheated – extreme temperature changes may make you ill, nauseated, or dizzy.
