Ready for summer? We sure are! Check out our forecast to see the Summer 2021 temperature and precipitation outlook for your area, compliments of Old Farmer’s Almanac meteorologist Michael Steinberg.
Summer officially begins with the summer solstice on Sunday, June 20! We plan to spend our time enjoying outdoor activities, seeing family and friends (finally), and generally having a better summer than last year. The only question is: will the weather cooperate?
Summer Weather Forecast 2021
Summer to Bring the Heat Again
Last summer brought record-breaking heat and drought to some areas of the United States. Are we up for a repeat performance this year? For a significant part of the country, we’re expecting summer temperatures to be hotter than normal once again, including in the Atlantic Corridor and eastern Great Lakes; from the Upper Midwest south to the southern Intermountain region; and into the Pacific Northwest, coastal California, and Alaska.
Elsewhere, we expect to see summer temperatures at near or below normal ranges—good news for those who suffered through the extreme heat of last year! We’re predicting near or below-normal temps from the Northeast into the Ohio Valley and south to the Gulf Coast, as well as westward across the southern border.
Rainfall will be greater than normal in the Northeast and eastern Great Lakes; from the western Ohio Valley south- and westward to the Gulf of Mexico; from Washington southward through California; and in northern Alaska and western Hawaii. It will be near or below normal elsewhere.

Across Canada, summer temperatures will be cooler than normal in Quebec and British Columbia and hotter than normal elsewhere. Rainfall will be abundant, with above-normal precipitation across nearly all of Canada.
Another Active Hurricane Season
As you may know, June 1 marks the official beginning of the Atlantic hurricane season, which runs until November 30. We expect near- or above-normal hurricane activity this year, but it’s likely that 2021 will fall far short of the intensity of the 2020 hurricane season, which brought a record-smashing 30 named storms.
The best chance for a major hurricane strike will be from South Carolina to New England in early to mid-August, with tropical storm threats in Florida in mid-May and from Florida to southern New England in early to mid-September.

July Forecast: Midsummer Respite?
July temperatures will be lower than normal, on average, in most of the U.S. and Canada, although Florida, the Upper Midwest, the High Plains, the Pacific Northwest, Alaska, the Canadian Maritimes and Prairies, and Yukon and the Northwest Territories will be hotter than normal. Rainfall will be below normal in most areas, although above normal in Maine, from the Gulf coast westward to California, from the Rockies to the Pacific, and in Kauai, the Canadian Maritimes, and British Columbia.
On July 1, Canada Day, showers will be scattered across all of the nation except for the Northwest Territories. Temperatures will be on the warm side in most areas, although cooler temps will prevail from Prairies eastward through Ontario.
Three days later comes U.S. Independence Day on July 4, when natural fireworks will light up the skies in many areas as scattered thunderstorms pop up everywhere except in the Southeast, Heartland, High Plains, California, and Alaska.
Many regions will also see thunderstorms on July 24, the National Day of the Cowboy in the U.S., but that weekend won’t be a total washout, as National Parents’ Day on July 25 will find most places dry with moderate temperatures and only the occasional threat of a thunder boom.
June Forecast: A Warm Start
Temperatures in June will be hotter than normal from the Northeast into the Appalachians, in the Upper Midwest, and in the eastern half of Canada, but near or below normal elsewhere. Rainfall will be above normal in the Northeast and Appalachians; from Florida westward across the Deep South; in much of Texas and the Pacific Southwest; and in the western three-fourths of Canada.
On June 5, World Environment Day, the outdoor environment will be good in most of the United States, with sunshine the rule. Bring your umbrella to any outdoor activities in Canada, though, as most areas will have at least a couple of showers.
Expect showers and cool temperatures to reign on June 11, King Kamehameha Day in Hawaii.
Between Flag Day (June 14) and Juneteenth (June 19) showers and thunderstorms will be scattered about most of the United States and Canada, although sunshine will prevail in the Intermountain region and Pacific states.
June 20 marks Father’s Day, as well as the summer solstice, the start of astronomical summer. Expect warm temperatures in most of the United States, with cool temperatures prevailing across most of Canada.
Expect showers and cool temperatures as the rule across Canada on June 21, National Indigenous Peoples Day, but don’t let this dampen the celebrations.
