Tri-State Swelters: Air Quality Alert Amid Heatwave
18 May
Summary
- Air quality alert for ground-level ozone is active through Monday.
- Elevated ozone levels pose risks to those with heart or lung conditions.
- Water temperatures remain in the 50s, increasing hypothermia risk.

An air quality health advisory has been issued for the New York metropolitan area, including the five boroughs, Long Island, Westchester, and Rockland counties, due to ground-level ozone. This alert is active through Monday evening and is expected to extend into Wednesday as a summery pattern brings significant heat to the Tri-State Area.
High temperatures will surge throughout the week, with highs potentially reaching the mid to upper 90s by Tuesday, possibly breaking record highs. This heat, combined with rising humidity, will create muggy conditions and exacerbate poor air quality. Ozone levels typically decrease at night and can be reduced during the day by limiting car travel and using public transportation.
While seeking relief at local beaches, visitors should be aware of the dangers. Water temperatures are still in the 50s, posing a high risk of hypothermia. Additionally, a moderate to high risk of rip currents is forecast through at least Wednesday. Cooler temperatures are anticipated to return after Wednesday, with highs in the 60s and 70s, possibly lasting through the holiday weekend.
