When Will Summer Start?

Technically, meteorological summer begins on June 1, while astronomical summer (marked by the June solstice) starts on June 20.

As for summery weather, predictions indicate a gradual buildup to record-breaking heat. June temperatures will be near normal in most regions (though not all), meaning the summer heat won’t surge too quickly.

However, July and August will bring above-normal temperatures across most regions, with only a few exceptions. Given recent trends, we wouldn’t be surprised to see record-breaking heat.

How Hot Will It Be This Summer? 

Last summer (2024), Americans endured one of the hottest summers on record, with a nationwide average temperature of 73.8°F, or 2.5°F above normal. It was also Earth’s hottest summer since global records began in 1880, barely surpassing 2023’s record.

The summer of 2025 is shaping up to be just as intense. As the map suggests, expect hotter-than-normal temperatures across most of the U.S., except for the Northwest and southern Florida.

• Texas and Oklahoma could see temperatures 4°F above normal.
• The Heartland states (including Kansas and Iowa) will also be 4°F above normal.
• The Deep South and Desert Southwest will experience significantly warmer conditions.

With heat waves likely, it’s essential to be prepared. Refresh your memory with quick tips on staying safe in extreme summer heat.

How Much Rainfall Will Summer Bring?

Unlike temperatures, summer precipitation isn’t expected to show extreme deviations. While much of the map is shaded in red, rainfall across most of the country will range from near to slightly below normal, particularly in the western half.

The driest conditions are expected in Texas, Oklahoma, and the Great Plains, where rainfall is likely to be lower than typical for these regions.

Meanwhile, above-normal rainfall is forecast south of the Great Lakes—including Illinois, Indiana, Kentucky, Michigan, and Ohio. Precipitation is also expected to be higher than normal in northern and central New England, southern Florida, Hawaii, and southern Alaska.
