Ready for August? We predicted that summer weather would be warmer than average this summer, and it looks like August continues that trend.

August Forecast: Late Summer Celebrations
August 3 marks Canada’s Civic Holiday, which is celebrated across most of the country and also known by a number of other more localized names. Although there may be some sun shining through at times, we expect showers to be dampening what celebrations there are in most places— but not Canadians’ indomitable spirit, of course!
With rainy periods everywhere except in New England and Ontario, Book Lovers Day (August 9) will be a good one for staying indoors to read.
The weather on the first day of the National Roller Coaster Weekend Celebration (August 15) will have its ups and downs. East Coast showers will throw us for a loop, the nation’s midsection will coast to sunny weather, and temperatures won’t dip much in the west, with hot weather on track to arrive.
National Lazy Day (August 10) and National Relaxation Day (August 15) are nearly back to back, so I should probably just chill instead of presenting the forecast. But chill won’t be in the air in many places, as above-normal temperatures will prevail during this time.
Finally, National Waffle Day (August 24) will not bring any waffling from us, as we pick that day to mark the first snow of the season to be sliding across northern Alaska like thick maple syrup, while showers will be scattered about all of Canada and most of the United States.
Summer Weather Forecast for the U.S.
Will It Be a Hot Summer?
If you like your summers nice and hot, you’re all set! Generally speaking, we’ve predicted that summer temperatures will be hotter than normal, with the hottest periods in mid-June, mid- to late July, and early August. Rainfall will be below normal in the north and above normal in the south.
June set the tone for the season. We predicted above-normal temperatures in the northeastern quarter of the United States, the Pacific Northwest, and Alaska; June temperatures were expected to be cooler than normal in most other areas, including Florida, the Southeast, the Intermountain region, and from Texas-Oklahoma west to the California coast.
Most areas were forecasted to have near- to above-normal rainfall in June, with drier weather expected in Northeast, Appalachians, Southeast, Desert Southwest, Pacific Northwest, Hawaii, and southern Alaska.
July will bring mostly good weather for outdoor activities—especially those near water—with temperatures above normal in nearly all of the northern half of the United States. In the Heartland and across the southern half of the United States, although temperatures will be near or slightly below normal, on average, there will still be plenty of hot days.
July rainfall will be below normal from the Northeast westward across the Great Lakes and Ohio Valley through the Upper Midwest and Heartland. Rainfall will also be below normal in the High Plains, Desert Southwest, and Pacific Northwest. Elsewhere in the United States, rainfall will be near or above normal, with well above–normal rainfall and many thunder bumpers in the Atlantic Corridor, Southeast, Deep South, Texas, and Oklahoma.
August will continue the trend of having good weather for outdoor activities, with summer temperatures near or above normal in most of the United States, although not as hot as normal from New England into Pennsylvania and New Jersey, in the Upper Midwest and Texas, from the Intermountain region and Desert Southwest to the Pacific, in Alaska, and on Oahu.
August rainfall will be below normal in Maine, around New York’s Finger Lakes, from Florida and the Southeast westward to Texas, and in the High Plains, Desert Southwest, southern Alaska, and Hawaii. Elsewhere in the United States, rainfall will be near or above normal.

Looking Ahead to Fall 2020
Dare we even speak of fall weather yet? Well, that is our job, after all.
Temperatures will drop as autumn arrives in September. The cooler-than-normal temperatures, on average, will linger through the month in most places, but don’t put away the t-shirts. Just when an early winter seems inevitable, October will roll in with milder-than-normal temperatures nearly everywhere—actually, make that “much warmer than normal” temps in the eastern two-thirds of the United States.
But enjoy it while it lasts: As the leaves begin turning color and floating to the ground, above-normal rainfall will visit the Deep South and Southeast and range northeastward to New England, as well as predominate from central California northward through the Pacific Northwest. Most other areas will be dry or nearly so.
As you may have heard, June 1 marked the official beginning of Atlantic hurricane season, which runs until November 30. We are predicting tropical storm activity to be near average, with the best chance for a major hurricane strike to occur in mid-September from Florida to North Carolina.
Other threats of hurricanes or tropical storms will occur in the same area in mid- to late June, in Florida in mid- to late July and mid- to late October, and in early to mid-October from the Deep South and Southeast northeastward to New England.

Summer Weather Forecast for Canada
A Hot One Up North, Too!
In June, temperatures were expected to be above-normal in almost all of Canada, save for the Atlantic provinces. Rainfall was predicted to be similarly above-average in most of the country, but drier weather was expected in the Atlantic Provinces, Quebec, and British Columbia.
In time for Canada Day on the 1st, summer temperatures will continue to be hotter than normal across the southern three-quarters of Canada. Northern Canada will be on the cool side during July. July rainfall will be above normal in most of the Canadian Commonwealth, although Atlantic Canada and the Prairies will be on the dry side.
Canadian temperatures will be above normal except from Quebec to central Ontario and in Saskatchewan and portions of British Columbia. August rainfall will be below normal in all of Atlantic Canada except Newfoundland and in Quebec and western Ontario and near or above normal elsewhere.
Autumn in Canada
Looking ahead to fall, we expect autumn temperatures to be above normal in Atlantic Canada, southern Ontario, the Prairies, British Columbia, and the Yukon and below normal elsewhere across the Canadian commonwealth. Precipitation will be below or near normal in Ontario and the Prairies and above normal in nearly all parts of the other Canadian provinces.
