We bring you the 2017 Summer Weather Forecast summary for the U.S. and Canada.

When we released The 2017 Old Farmer’s Almanac last fall, we predicted cooler than normal temperatures in the Northeast and Desert Southwest, but a warmer than normal spring elsewhere. In this same issue, we’re predicting a range of temperatures across the U.S. and Canada for the summer season. 

Summer Forecast 2017

In the United States, summer temperatures will be above normal in the Pacific and Intermountain states, but the heat will be kept at bay in the Northeast, Atlantic Corridor, and down through the Deep South, resulting in below normal temperatures. Rainfall will be below normal in much of the Ohio Valley, Deep South, Upper Midwest, Heartland, High Plains, and Oklahoma and northern Texas, but near or above normal elsewhere.

In Canada, summer temperatures will be above normal, on average, in the Atlantic and Pacific provinces, but below normal in the interior. Rainfall will be above normal in Quebec, from western Ontario westward through Alberta, and in western British Columbia, but near or below normal elsewhere.

Hurricane season will be more active along the Atlantic seaboard than along the Gulf Coast. The best chances for a major hurricane strike are in mid-June from Florida to New England and in late August and early September from Florida to North Carolina. Find out the names of this year’s hurricanes here.

With the arrival of the summer solstice, this year occurring on June 21 at 12:24 a.m. EDT, enjoy a long day of light, with one of the earliest sunrises and latest sunsets of the year. See sunrise and sunset times by location.

August weather

Hi, Jill, Thunderstorms are forecast intermittently through August, broadly speaking, in the locations you cite. It’s summer, and thunderstorms happen in August. And in July, as we’re seeing. As for driving vs flying, speaking personally, would you rather be on the ground or in the air in such an event? Only you can answer that. We appreciate your faith in our forecasts. Please understand that thunderstorms typically just pop-up. We predict them for some days and not others but that does not mean that they will not occur on those “other” days. Have a safe trip! It’s beautiful country—both of them!

Hello, I am trying to find

Hello,

I am trying to find forecast information for SK, AB and ON Canada for Summer and Fall 2015 (and Spring if possible) that shows in detail (the specific area (ie: southern SK (Regina area) or Calgary, AB area). I am seeking temperatures in order to estimate potential hail storms. I am looking for sudden notable changes in temperature hot/cold cold/hot.

We are in the catastrophe relief business and this would be very helpful for planning and preparation.

Thank you,
Leannie

Taken together, these two

Taken together, these two maps don't make sense to me.

Looking at the mostly Canadian map, it shows dry in the
western area (shown in red) and wet for the rest of the
country (shown in green). The red Canadian area shades to
a salmon color (dry) as it goes through the United States.
The green Canadian area shades to a light green (wet) as it
goes into the USA.

On the USA map, the red dry area shades to salmon (dry) in
Canada, which is green (wet)on the Canadian map. Also on the USA map, the green (wet) area shades to a light green
(wet), which is red (dry) on the Canadian map.

Also, how can Canada be wet and right across the border in
the United States, it is dry.

This is all very confusing.

William, Look at the

William,

Look at the interactive maps to identify the region. The forecasts are specific to the region, not to the state/province. Those two maps are just generalized maps for overview purposes.
