Summer is almost here, and with it comes warm temperatures throughout much of the U.S. Sure, summer is always hot, but in 2024, Americans experienced one of the hottest summers on record, according to the National Oceanic and Atmospheric Administration, with a nationwide average temperature of 73.8°F, or 2.5°F above normal.
It wasn’t just the U.S., Last summer also marked the Earth’s hottest summer since global records began in 1880, and before then, 2023 was the hottest. So, it’s really showing that the Earth is getting hotter each year.
“The summer of 2025 is shaping up to be just as intense,” the Farmer’s Almanac notes. “As the map suggests, expect hotter-than-normal temperatures across most of the U.S., except for the Northwest and southern Florida.”
Summer 2025 Forecast
They add that Texas and Oklahoma could see temperatures go 4°F above normal, the Heartland states could also be 4°F above normal and the Deep South and Desert Southwest will also “experience significantly warmer conditions.”
Looking at the Farmer’s Almanac’s map of the U.S., most of the U.S. is marked as being “hot,” with only the Northwest being marked as “cool.”
This is a long-range forecast, so don’t expect to see a 10-day forecast in their projections.
“The Almanac provides long-range seasonal forecasts to give a general idea of what to expect across the United States and Canada,” the Almanac noted. “This general weather report, compliments of the 2025 edition, covers the 3 months of summer — June, July, and August — focusing on temperature and precipitation trends compared to historical 30-year averages, updated every decade.”
Overall, the Almanac says it’s going to be a “scorcher” of a summer.
“For gardeners and farmers, this means preparing irrigation systems and using water-saving techniques,” they added. “Homeowners should ensure their air conditioning is in top shape and find ways to stay cool.”
Looking to Canada, “Cooler-than-normal temperatures are expected from Atlantic Canada through Quebec and around Hudson Bay.”
Summer Facts
So, when does summer start? According to Britannica, “It begins on the summer solstice, which occurs on June 20 or 21 in the Northern Hemisphere and on December 21 or 22 in the Southern Hemisphere.”
Time and Date adds, “The summer solstice marks the start of summer. In the Northern Hemisphere, the summer solstice is in June; south of the equator, it is in December.”
Space adds, “The summer solstice marks the official start of astronomical summer and the longest day of the year. It occurs when one of Earth’s poles is tilted toward the sun at its most extreme angle, and due to Earth’s tilt, this happens twice a year.”
They add that, “In the Northern Hemisphere, the summer solstice falls in June (while the Southern Hemisphere experiences the winter solstice), and in the Southern Hemisphere, it falls in December (while the Northern Hemisphere experiences the winter solstice).”
