A few months ago we discussed building a Family Emergency Binder and a Family Emergency Plan. Then, a few weeks ago, I wrote a post about what to do in case of power outages and wildfires. Those posts discuss about how to protect your family from disasters and how to rebuild your life after an emergency. But now that we’re in midsummer, the heatwaves haven’t let up.
Summer can be a season of beauty—long days, barbecues, fireflies—but when the temperature spikes, it can quickly become dangerous. Heatwaves are one of the deadliest natural hazards in the United States, affecting thousands each year. And while they can strike almost anywhere, not everyone knows how to prepare for them or how to respond when extreme heat hits home. This post isn’t about panic. It’s about practical, proactive preparation. Whether you’re staying local, traveling, or helping others get ready, here’s a round-up of reliable, expert guidance to help you stay cool, stay safe, and stay informed.
🔗 How to Prepare for and Deal with Heatwaves
🌡️ What Is a Heatwave?
A heatwave is typically defined as a prolonged period of excessively hot weather, which may be accompanied by high humidity. The threshold varies by region, but the impact is often the same—dangerous conditions that can lead to heat exhaustion, heat stroke, and even death if not addressed.
🧊 Before a Heatwave: How to Prepare
Since preparation is your best defense, here is a list of trusted resources to start with:
- CDC Extreme Heat Preparedness Guide
- This site offers symptoms of heat-related illness, tips on home safety, and guidelines for staying cool.
- Ready.gov Heatwave Prep
- This site covers how to prepare your home, what to do if the power goes out, and how to check on neighbors.
- National Weather Service (NWS) Heat Safety Tips
- Get real-time heat alerts and learn how to interpret Heat Index values and advisories.
- AirNow.gov
- This is the home of the U.S. Air Quality index that tracks air heat and air quality.
Easy Checklist Before the Heat Hits:
- Install or service your air conditioning units or fans
- Create a go-kit in case of power loss or forces evacuation
- Identify local cooling centers (libraries, malls, community centers)
- Stock up on bottled water, electrolyte drinks, and cooling towels
- Talk to family members about safety plans, especially vulnerable loved ones
☀️ During a Heatwave: What To Do
- Stay indoors during peak heat hours (10 am – 4 pm)
- Drink water regularly and DO NOT WAIT until you’re thirsty
- Wear lightweight, loose-fitting clothing in light colors
- Take cool showers or baths to lower your body temp
- Avoid alcohol, caffeine, and heavy meals
- Use fans wisely. If temps are above 95°F and humidity is high, fans may circulate hot air rather than cool you off.
If you must go outside:
- Schedule outdoor work early or late in the day
- Drink water all day long
- Wear sunscreen and a wide-brimmed hat
- Rest often in the shade and stay hydrated
⚠️ Know the Signs: CDC’s Rundown on Heat Related Illnesses
- Heat Exhaustion: Dizziness, nausea, heavy sweating, weakness
- Heat Stroke: Confusion, fainting, rapid pulse, no sweating—this is a medical emergency. Call 911.
🧓 Vulnerable Populations
- National Weather Service’s Health and Heat Tracker
Children, the elderly, people with chronic illnesses, and pets are especially vulnerable during heatwaves. This tool identifies at-risk populations and tracks heat-related health concerns by region. According to the NEWS, “NWS HeatRisk is supplementary to official NWS heat watches, warnings, and advisories. It provides guidance for decision makers and those who are sensitive to heat.
🐕 Pet Safety Tips
Humane World for Animals has a great rundown on to keep pets safe in the heat. Below are a few of the basic tips:
- Never leave pets in cars
- Keep them indoors in cool areas
- Ensure water is always available
- Walk them early or late in the day
💡 Community Cooling & Local Support
- Find a Cooling Center:
Many cities open public buildings during heatwaves. Check with your local emergency management office or community health department. - Local Assistance:
If you’re struggling with utility bills or A/C costs, contact LIHEAP – the Low Income Home Energy Assistance Program.
🔁 After the Heat Breaks
Once the temperatures drop:
- Check on neighbors, especially seniors
- Rehydrate and rest
- Inspect your home and appliances for any heat-related damage
- Reflect on what worked well and what could be improved for next time
