Understanding Weekly Heat Wave Trends in the United States

Heat waves are becoming more frequent and intense across the United States, significantly impacting public health, agriculture, and infrastructure. Understanding the weekly trends of these extreme heat events is crucial for effective preparation and response.
What Are Heat Waves?
A heat wave is a prolonged period of excessively hot weather, which may be accompanied by high humidity. In the U.S., a heat wave is typically defined as a period of at least two consecutive days with temperatures exceeding the average by 5°F (2.8°C) or more.
How Do Heat Waves Develop?
Heat waves often result from a high-pressure system, known as a "heat dome," which traps warm air over a region. This system can lead to prolonged periods of high temperatures and humidity. For instance, in June 2025, a heat dome affected over 200 million people across the central and eastern U.S., bringing temperatures at or above 100°F (37.7°C) to numerous cities. (theguardian.com)
Weekly Heat Wave Trends
Heat waves can vary in frequency and intensity throughout the year. In the U.S., they are most common during the summer months, particularly in June, July, and August. However, with climate change, the duration and severity of heat waves have been increasing. The average annual frequency of heat waves across the United States has more than tripled since the 1960s.
