Meteorological Summer Starts June 1, Forecasts Show Hot Days Ahead

California, USA — Meteorologists confirm that meteorological summer began on June 1, with the hottest three months of the year expected ahead. This differs from the astronomical start of summer, which officially begins on June 20 this year.

Meteorologists and climatologists use June 1 as the starting point for summer because it aligns with the average temperature patterns, rather than the Earth’s position relative to the sun. The summer months are defined as June, July, and August, while December, January, and February mark winter.

The National Oceanic and Atmospheric Administration (NOAA) reports that summer 2025 is forecasted to bring hotter-than-normal temperatures across the entire United States. “Model guidance was overwhelmingly above normal across the U.S. and most of Alaska for the upcoming summer season,” said Johnna Infanti, a meteorologist with NOAA’s Climate Prediction Center.

The predictions indicate no part of the U.S. is expected to see cooler-than-average summer temperatures. The West, Southwest, Florida, and New England may experience an increase in heat, while regions like the Northwest and Northern Rockies face potential drought conditions due to below-normal precipitation.

In contrast, the Eastern U.S. may experience a wetter summer, providing some drought relief. However, a greater likelihood of wildfires is anticipated, especially in areas like the coastal Southeast and parts of Texas and California during June, transitioning to other regions in July and August.

Forecasts also warn that smoke from wildfires in Canada may affect air quality in the northern U.S. “It’s important for individuals sensitive to air quality issues to remain cautious as smoke could be a concern throughout the summer,” noted AccuWeather meteorologist Paul Pastelok.

With summer on the horizon, residents are urged to prepare for potential heat waves and increased fire risks.
