Forecast: Bostonians cope as sticky heat wave keeps up
ResumeGet ready to sweat, Boston.
A strong ridge of high pressure, both at the surface and upper levels of our atmosphere, is driving scorching temperatures and sticky humidity to the region this week.
Temperatures will soar into the 90s, right on cue with the official start of summer on Thursday, June 20.
The last time Boston hit 90 degrees was back on September 7, 2023, so it's certainly been a while. In fact, the last heat wave (defined as three consecutive days or more with temperatures at or above 90 degrees) was nearly two years ago — for six days in August 2022.
Feeling the heat
Heat index values, which consider both temperature and humidity, show it will feel even hotter than the forecast suggests. When it's humid, sweat evaporates slowly, making it harder for your body to cool down. Heat index values Tuesday through Thursday will range from 95-105.
Staying safe in the heat
Heat is the deadliest type of severe weather in the United States. Here are some tips to stay safe during the heatwave:
- Beat the heat: Plan strenuous activities for the early morning or evening hours, and seek out air conditioning or shaded areas during the hottest part of the day.
- Hydrate: Drink plenty of water, even if you don't feel thirsty. Avoid sugary drinks and alcohol, which can dehydrate you.
- Take breaks: If you're working or exercising outdoors, take frequent breaks in cool spaces to lower your body temperature.
- Listen to your body: Be aware of heat exhaustion and heatstroke symptoms like dizziness, headache, and excessive sweating. If you experience these, move to a cool place, drink fluids, and seek medical attention if needed.
Scattered storms possible
While the heat is the main story, there's a slight chance of isolated thunderstorms later this week, especially on Thursday and Friday. The weekend looks to bring some relief from the scorching temperatures, with highs returning to the 80s, but muggy conditions are expected to linger.
Little relief overnight
Temperatures will only drop into the lower 70s each night downtown, and in the upper 60s in the suburbs. With sticky air remaining in place, relief will be minimal.
