Don’t let this breezy, rainy weekend lull you into comfort—by midweek, it’ll feel like you stepped into an oven. Poughkeepsie and Kingston are both on track to hit 90°F or higher by Wednesday, as a sudden and intense heatwave tightens its grip on the Hudson Valley.
The rapid warm-up, paired with high humidity, could send heat indexes soaring closer to 95°F. And after several cooler days in the 60s and low 70s, this jarring temperature swing could catch many off guard—and unprepared.
Heat Timeline: When the Real Sweat Starts
Monday (June 16):
Skies begin to clear and temperatures warm into the mid-70s. It will still feel comfortable—but this is just the start.
Tuesday (June 17):
Humidity rises sharply, and daytime highs will push into the upper 80s. You’ll likely notice how thick the air feels, and by evening, conditions will be downright muggy.
Wednesday (June 18):
Here’s the main event. Forecasts project highs around 90 to 92°F, with dew points climbing into the upper 60s. That combination means it could feel like 95°F or more outside during peak afternoon hours.
Why This Heatwave Is Dangerous
This mid-June scorcher is more than just uncomfortable. Here’s what makes it a legitimate hazard:
-
Rapid temperature shift: After several days of cooler, cloudy weather, the body has less time to adjust. That increases the risk of heat exhaustion, especially for children, seniors, and anyone working outside.
-
High humidity = higher risk: Moist air traps heat close to the skin, making it harder for sweat to cool you down. Even in the shade, it can feel oppressive.
-
Air quality issues: The heat may trap pollutants near the ground, making breathing harder—particularly for asthma or allergy sufferers.
What You Should Do to Stay Safe
-
Hydrate now and often. Don’t wait until you’re thirsty—drink water throughout the day.
-
Reschedule outdoor work and errands to early morning or late evening.
-
Avoid overexertion, especially during workouts or yard work.
-
Wear loose, light-colored clothing. Dark clothes absorb heat.
-
Check on vulnerable neighbors—especially elderly folks, those without AC, or anyone living alone.
-
Never leave kids or pets in cars—even for a minute.
-
Use fans and air conditioning wisely. Keep blinds closed to block out sun.
-
Know the signs of heat illness: Dizziness, nausea, rapid pulse, and confusion are signs it’s time to cool down—immediately.
What Comes After?
The heat may break slightly on Thursday and Friday, with a few afternoon thunderstorms in the forecast and highs retreating to the mid-80s. But don’t expect relief from the humidity. It will still feel muggy, and more warm weather is likely into next weekend.
Summary
This isn’t a subtle start to summer—it’s a full-throttle, sweat-drenched kickoff. From Wednesday onward, the Hudson Valley will feel the full force of June heat. Plan now so you’re not scrambling once it arrives.
