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.

Thanks for this question. In the short term at least, we don't expect the changes at NOAA to have much effect on our forecasts. Much of what we rely on NOAA for is long-range data that will still be available to us. That said, this is a situation we are watching closely and are certainly concerned about. NOAA's work is important well beyond its impact on our yearly forecasts, and I hope appropriate funding will be restored as soon as possible.
Hi, Emily,
We're glad that you have found the Almanac's forecasts useful! From what I understand from NOAA and elsewhere, experts are expecting the ENSO to be neutral throughout the Northern Hemisphere at least through the summer months, after which there is a slight chance of a La Nina taking over, although the chances are still more likely that neutral conditions will continue.
During a neutral ENSO state, it is harder to predict trends, as the patterns of a La Nina or El Nino are less prominent, allowing other influences to take over. In general, the trend would tend to be average rainfall for the summer in the Northeast, but that depends on what other factors are in play at the time. Consequently, there might be major variations in rainfall between areas of the Northeast, with some drier than normal and other places wetter than normal.
Thank you for your interest in The Old Farmer's Almanac.
Best,
The Almanac Editors
