Long Island Heat Advisory: Feels Like 100° Today
Long Island Heat Wave: What You Need to Know This Week
The Big Picture: It’s Hot and Sticky Outside!
Imagine walking outside and feeling like you just opened an oven door. That’s what Long Island felt like on Sunday, with temperatures climbing close to 90°F. And guess what? The hot, steamy weather isn’t leaving anytime soon.
The National Weather Service (that’s the official government team that predicts weather) says we’re in for several more days of heat, plus some possible storms.

What Is the "Heat Index"? (ELI5 Explanation)
Think of it like this: The thermometer says 88°F, but your body feels like it’s 95°F.
Why? Humidity (moisture in the air) makes it harder for sweat to evaporate off your skin. Sweat is your body’s natural air conditioning. When it can’t evaporate, you stay hot. The "heat index" combines temperature + humidity to tell you what it actually feels like on your skin.
IMPORTANT: Heat Safety Checklist
Don’t skip these! Heat illness can sneak up on you, especially after several hot days in a row.
- Drink water — even if you’re not thirsty
- Add electrolytes — sports drinks, coconut water, or electrolyte powders help replace what you lose in sweat
- Take shade breaks — every 15–20 minutes if you’re working or playing outside
- Apply sunscreen — every 2 hours (set a timer on your phone!)
- Wear light, loose clothing — think cotton t-shirts, not tight polyester
- NEVER leave kids or pets in a parked car — not even for "just a minute"
- Check on neighbors — especially elderly folks or anyone without AC
Special Advice for Outdoor Workers
If your job keeps you outside (construction, landscaping, delivery, etc.):
- Schedule heavy tasks for early morning if possible
- Use the buddy system — watch each other for signs of heat exhaustion
- Take more breaks than you think you need
- Know the warning signs: dizziness, nausea, headache, cramps, confusion

FAQ: Your Heat Wave Questions Answered
1. What’s the difference between a "Heat Advisory" and an "Excessive Heat Warning"?
A Heat Advisory means conditions are hot and humid enough to be dangerous if you’re not careful. An Excessive Heat Warning is more serious — it means heat index values are expected to hit 105°F+ for at least two hours. Right now, we’re under an Advisory.
2. Do I really need to reapply sunscreen every 2 hours?
Yes! Sweat, wiping your face, and time all break down sunscreen. Even "water-resistant" kinds wear off. Set a phone alarm — your future skin will thank you.
3. Are sports drinks better than water?
For most people doing normal activities, water is fine. But if you’re sweating heavily for over an hour (working outside, sports practice, long hike), a drink with electrolytes helps replace sodium and potassium you lose in sweat.
4. How can I tell if someone has heat exhaustion vs. heat stroke?
| Heat Exhaustion (Serious) | Heat Stroke (Emergency — Call 911!) |
|---|---|
| Heavy sweating | Hot, dry skin (no sweat) |
| Cool, pale, clammy skin | Red, hot skin |
| Weakness, dizziness | Confusion, passing out |
| Nausea | Very high body temp (103°F+) |
| Muscle cramps | Seizures |
For heat exhaustion: Move to shade, sip water, cool with wet cloths. For heat stroke: Call 911 immediately — do NOT give fluids.
5. Will the storms Monday and Thursday cool things down?
They might bring temporary relief during the rain, but humidity often stays high afterward. Don’t count on a big cool-down — keep up the heat safety habits all week!
