Houston summers are known for their heat, but sometimes that heat reaches the extreme end of the spectrum.
That’s exactly what we’re experiencing right now.
With the perfect combination of abundant humidity, an intense heat dome overhead, and peak summertime heating, conditions can become dangerously hot. This week is expected to bring some of the hottest temperatures of the year, making it important to understand the forecast and know how to protect yourself from heat-related illnesses.
This week’s forecast
This is forecast to be the hottest week of the year so far. A Heat Advisory is in effect today and is expected to remain in place through the end of the workweek.
Afternoon air temperatures are forecast to reach 100–102°F, but that’s only part of the story. Once humidity is factored in, heat index values—or what the temperature actually feels like to the human body—are expected to climb to 108–110°F.
These conditions can become dangerous very quickly, especially for anyone spending extended periods outdoors. Prolonged exposure to extreme heat increases the risk of heat-related illnesses, including heat exhaustion and heat stroke.
Recognizing heat illness
Knowing the warning signs of heat-related illnesses can help save a life. The National Weather Service provides guidance on recognizing and responding to heat exhaustion and heat stroke.
For heat exhaustion, watch for symptoms such as:
- Dizziness
- Excessive thirst
- Nausea
- Weakness
- Heavy sweating
If you or someone else experiences these symptoms, move to a cooler location immediately, loosen clothing, sip cool water, and rest. If symptoms do not improve or begin to worsen, seek medical attention promptly. Left untreated, heat exhaustion can progress to heat stroke.
If someone becomes confused, dizzy, loses consciousness, or stops sweating despite the extreme heat, they may be experiencing heat stroke, which is a life-threatening medical emergency.
If you suspect heat stroke:
- Call 911 immediately.
- Move the person to a cooler area.
- Remove or loosen excess clothing.
- Cool the person with water, ice packs, or cool towels while waiting for emergency responders.
Without immediate treatment, heat stroke can lead to permanent disability or death.

Heat Safety Tips
Before heading outdoors, take steps to reduce your risk of heat-related illness.
- Drink plenty of water throughout the day and pre-hydrate before outdoor activities.
- Take frequent breaks in shaded or air-conditioned areas.
- Wear lightweight, light-colored clothing.
- Avoid strenuous outdoor activity during the hottest part of the afternoon whenever possible.
- Check on elderly neighbors, young children, and others who may be more vulnerable to the heat.
Most heat-related illnesses are preventable with proper planning and awareness.
Never Leave Children or Pets in a Vehicle
Every year, children and pets lose their lives after being left inside hot vehicles. Interior temperatures can exceed 108°F within minutes, creating life-threatening conditions even if the outside temperature doesn’t seem excessively hot.
Some tragedies occur when children gain access to an unlocked parked vehicle without supervision. Always lock your vehicle when it is parked, even if you do not have children.
If you cannot find your child, check your vehicle immediately. Make it a habit to check the back seat every time you exit your vehicle. Hot car deaths have occurred during every season of the year—even when outside temperatures are below 70°F.
Never leave a child, pet, or any person inside a parked vehicle without air conditioning or adequate airflow.
