What is the urban heat island effect?
The urban heat island effect is when urban areas retain more heat than rural areas due to the abundance of concrete and asphalt.

Summer 2025: NOAA Forecasts Above-Average Temperatures Across the U.S.
The National Oceanic and Atmospheric Administration (NOAA) is forecasting a hotter-than-average summer for much of the United States in 2025. The Climate Prediction Center (CPC) warns of above-average temperatures across most of the Lower 4...
Key Insights
- NOAA’s Climate Prediction Center forecasts above-average temperatures across most of the U.S. for summer 2025.
- Regions at high risk include the West, Gulf Coast, and Northeast, with potential for record-breaking temperatures.
- Urban areas are particularly vulnerable due to the urban heat island effect, increasing the risk of heat-related deaths.
- The forecast also projects below-normal precipitation for the Northern Rockies, Northwest, and central parts of the Great Plains, raising wildfire risks.
In-Depth Analysis
### Regional Impacts
**The West and Southwest:** Expect record-breaking high temperatures in cities like Phoenix, Las Vegas, and Albuquerque, potentially exceeding 115°F.
**The Gulf Coast and Florida:** High humidity will exacerbate heat index values, creating dangerous conditions.
**The Northeast and New England:** Cities like Boston, Hartford, and New York City may experience more frequent 90°F+ days, straining infrastructure.
**Pacific Northwest:** Adaptation is critical as cities like Seattle and Portland are under threat of multiple heat domes, similar to the deadly 2021 event.
### The Urban Heat Island Effect
Urban areas retain heat due to concrete, asphalt, and limited green space. For example:
- Philadelphia is expected to exceed 40 days over 90°F, up from a historical average of 34.
- Houston and Dallas could face “dangerously hot” periods with overnight temperatures staying above 80°F.
### Wildfire Threats
Below-normal precipitation in the Northern Rockies, Northwest, and central parts of the Great Plains increases wildfire risk. High-risk zones include the Coastal Southeast, Central Texas, Four Corners region, and Northern and Southern California.
### Preparing for the Heat
**Personal Safety Tips:**
- Stay hydrated.
- Avoid strenuous outdoor activity during peak heat hours.
- Wear light, breathable clothing.
- Seek air-conditioned spaces or cooling centers.
**Community-Level Adaptations:**
- Expand green spaces and tree cover.
- Install reflective rooftops and pavements.
- Establish early warning systems for heat alerts.
- Subsidize access to air conditioning for low-income households.
