With a heat advisory in effect through Saturday, August 8 — heat indices up to 98°F with little overnight relief — the question isn’t whether to go outside this weekend, it’s when and where. Here’s how to still get outdoor time without it turning into a heat-illness risk.
Time It Right
As a general rule of thumb, the hottest, highest-risk stretch of the day tends to fall in the late morning through early evening, when heat and sun exposure stack. Consider shifting outdoor plans toward early morning or evening, when temperatures are typically a little lower — though this is general guidance, not a guaranteed safe window, so still watch how you feel and take breaks as needed. If your plans for outdoor events like the August Moon Festival or Open Newbury Street this weekend allow for it, breaking up the day with an indoor, air-conditioned stretch is a reasonable option — but only if the event’s schedule and any re-entry policy actually support leaving and coming back.
Know Your Nearest Cooling Center
Boston Centers for Youth & Families locations are open as designated cooling spaces through Saturday during normal hours, and additional resources — including some library branches and public pools — are listed on the city’s current cooling-resource page. No fee, no appointment needed. Find the closest option and confirm hours at boston.gov/heat or by calling 311, since the specific list of open locations can change.
Seek Shade and Carry Water
Shaded routes through the Emerald Necklace (the connected chain of parks running from the Back Bay Fens through Jamaica Pond and beyond) or along the Harborwalk are generally more comfortable than open pavement, simply from tree cover and a breeze off the water. Carry water regardless of how short the outing feels — heat illness can build faster than people expect, especially with the limited overnight relief this advisory is forecasting.
On Storm Risk
Don’t assume thunderstorms are coming just because a heat wave is underway — that’s not a given. If you want to know whether storms are actually forecast, check the National Weather Service directly rather than treating this heat advisory as a storm warning. If skies do darken or you hear thunder while you’re out, treat it seriously and head indoors.
Who to Check On
If you’ve got elderly neighbors, anyone without reliable air conditioning, or pets, make time to check on them specifically this weekend — they’re the highest-risk groups when nights don’t cool down enough to give the body a break.
