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.

I am hoping it is right, a rainy and cool summer for us.
I am hoping for mildly dry, not so humid weather in the Pocono Mountains of Pennsylvania. A little rain here and there is fine, but please no scorching heat like I experienced living outside of Philadelphia for years.
This past Winter was very dry, and the predicted very hot Summer gives me the shivers and concern about wildfires in the West.
Month of June rained but two days in NH. July is already showing rain for another ten days. It’s been cold and raining. Tell them to stop messing with the weather. I don’t care if you want to block the sun we want it
I’m glad I live California wit GREAT WEATHER except for the GOVENOR
I posted in my Facebook gardener's group about all this rain and lack of sunshine in Western New York. My fellow gardeners are loving all this rain. To me, it's too much. It feels like late April- early May temperature and weather condition wise. I'm ready for blue skies, warmth, and sunshine.
We are from New Hampshire, too. We are ready for the sunshine!
Hear hear! I agree! Sick sick SICK of this rain! My garden is being devoured by slugs! I don't think we've gone 48 hours with our some kind of rain! UGH!

You were so correct about last summer in region 1, NW Massachusetts. It was so wet, my carrots rotted in the ground, many other plants died or the vegetables rotted, even in raised beds, and I had such an onslaught of slugs. I would pick off a couple hundred a day, but they also liked eating the vegetables, especially broccoli family and squash. I hope you are wrong about this summer also being wetter!! Tried to add photos of my rotting carrots, squash and slugs, but they won't show here.
