Although most of us may not be going anywhere at the moment, the calendar is still marching onward and summer will be here before we know it. Find out what sort of weather’s in store in The Old Farmer’s Almanac’s extended summer forecast for the United States and Canada!
Summer Starts With the Solstice
Summer officially begins with the summer solstice on Saturday, June 20, at 5:44 PM EDT. It’s the day of maximum sunlight in the Northern Hemisphere, which is certainly something to look forward to!
The first full day of summer happens to be Father’s Day (Sunday, June 21), and the forecast for that weekend is looking ideal for Dad to fire up the grill in the Atlantic Corridor, from the Ohio Valley northward to the Lower Lakes, in the Heartland, from the Desert Southwest westward to the Pacific Southwest, in most of Alaska, and in the Northwest Territories of Canada.
Most other areas will have mainly dry weather, but thunderstorms will be scattered about. Showers will be more widespread in Hawaii and the Pacific Northwest and especially from Florida into the southeastern states, where a tropical storm is possible.
Summer Weather Forecast for the U.S.
Will It Be a Hot Summer?
For a large part of the United States, this summer is likely to be a scorcher!
June will set the tone for the season, with above-normal temperatures in the northeastern quarter of the United States, the Pacific Northwest, and Alaska. June temperatures will be cooler than normal in most other areas, including Florida, the Southeast, the Intermountain region, and from Texas-Oklahoma west to the California coast. Temperatures in those regions will still be warmer than those predicted for May, however.
Most areas will have near- to above-normal rainfall in June, but drier weather will be the rule in the Northeast, Appalachians, Southeast, Desert Southwest, Pacific Northwest, Hawaii, and southern Alaska.

A Muggy Mid-Summer for Some
Summer’s steamiest weather will hold off until mid-July in most areas. Gardeners almost everywhere—in the Intermountain and Pacific regions, northern Alaska, from most of Texas northward to Canada, and eastward to the Atlantic—may be relieved to hear that summer rainfall will be above normal. I’m sorry to say, however, that watering cans will be needed in the Sunshine State (Florida).
Hurricane Season Begins on June 1
Of course, June 1 marks the official beginning of Atlantic hurricane season, which runs until November 30. Tropical storm activity will 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, summer temperatures are expected to be above-normal in almost all of Canada, save for the Atlantic provinces. Rainfall will be similarly above-average in most of the country, but drier weather is predicted for the Atlantic Provinces, Quebec, and British Columbia.
Later in the season, summer temperatures will continue to be hotter than normal across the entire Canadian Commonwealth. Rainfall will be below normal in most of Atlantic Canada and in a swath from western Ontario northward to southeastern Nunavut, and above normal elsewhere.
