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.

Monthly Forecasts

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.

July 2021

Well, so far, as of July 8th 2021, NW Ohio has been hot very muggy, sticky, with very high humidiy and lots of rain. Quite uncomfortable to say the leat, May was high humidity, so was June. Never seems to be a happy medium.

"Major hurricane" for east coast?

As much of a fan of the Almanac as I am, I really hope you end up being wrong about a "major hurricane strike" from South Carolina to New England in early-mid August. I live on Long Island (NY) and we were slammed by Hurricane Sandy in 2012. Not looking forward to another such situation (or worse). Especially in the summer heat and humidity.

Small Town farms, farmers, gardeners and such!

Dear Old Farmer's Almanac. Would you please place a store in my small home town of Batesburg, South Carolina. Ridge Spring South Carolina, Saluda, South Carolina (where I went to school,) Edgefield, South Carolina, Orangeburg, South Carolina, Aiken, South Carolina, Greenwood, South Carolina, West Columbia, South Carolina, Camden, South Carolina and Columbia, South Carolina. I believe we could use a store (actual brick and mortar store--to go along with the internet.) Not just a section IN a store, sirs. Although that is present in our Batesburg-Leesville hometown Ace Hardware store--Bob's Ace Hardware, but I would like an actual Old Farmer's Almanac store in town.
I began reading Old Farmer's Almanac again, that I purchased at Books-A-Million, because I did not have any clocks and needed to know the time. You see, gentlemen, I have long wanted a sun-dial in my yard, but I don't really know how to read one. I still want want though! I figured that I could learn how to use my "real" sundial--then, if I didn't have a watch, I could still know the time of day. I remembered high school where I was taught from The Old Farmer's Almanac about many things concerning weather and time. I also remember my Granddaddy's Old Farmer's Almanac and our family's (extended family) conversations while reading The Old Farmer's Almanac. My granddaddy raised peanuts, cashews, and cherry trees! He also raised other vegetables, but I was really, really young and I don't remember everthing that he raised. But I loved talking to my granddaddy and watching the older grandchildren talk about grandaddy's peanuts, etc. Yes, I was listening! Even as a child!
Later, I learned about The Old Farmer's Almanac in school. I believe it was history class; so, therefore, I also learned about "Poor Richard's Almanac, and others." These recollections helped me to decide to try to learn how to tell time from The Old Farmer's Almanac, the weather, AND gardening!!! You see, I'm excited about my new house and I want to raise all sorts of vegetables AND fruit trees. As long as my yard and various South Carolina "zones" will permit good growth. I'll just have to experiment along with the new information that I receive and information that I believe I can remember from YEARS ago! I'll just start with water as I have started in my gardening experiences before--which were usually just a few flower pots, but I was an aspiring home owner and farmer. I never really told many people about my desire to own a farm though--but, now I'm beginning to do just that. One person from the USDA even suggested that I have a much larger farm than one with just a few chickens, ducks, geese, cats, dogs, a jersey cow, an iguana, a pond, and at least two birds. Believe me sirs, that's not all. Which, sirs, you bringinging a new brick and mortar Old Farmer's Almanac Store to small towns is where you come in-- I do hope!!
In my business plans sirs, I have chosen with delight to focus on small towns across the country and the world--later, to do business in--establishing "something to do in a small town!" You see sirs, as much as I love my home. Sometimes, I get bored! Or, I get so inspired in my home town with a new idea, that I think that my small town may not be big enough to acommodate such ideas--at least sirs, I use to think that way. I no longer think that way. Sometimes, you just have to give things a try--that's what the frontiersmen used to do that I used to study about with fascination; how they built houses with axes; traveled clear across America with an ax, a map, and some hope. Also, sirs some gumption! Maybe, they didn't always have a lot of money or banks either--just a whole lot of land to be cleared that they probably heard about from someone else who wanted to make new discoveries with the will to risk something "new." That sirs, experiencing something new, is what I'm doing now and yes, sirs, in a small town. I have built my business plan around small towns and back to basics planning--right down to the materials I use. A pen and some notebook paper or lineless paper. It's not fancy--but my plans for Batesburg-Leesville, my small hometown and its function is fancy. Something I hope a whole lot of people will like, look forward to, and be willing to travel across the world to see; so, I hope you will consider coming to Batesburg-Leesville with a new "Old Farmer's Almanac Store and all that you have to bring from your almanac--please consider hardily those other towns as well. Thank you for your consideration, gentlemen. My name is Keisha L. Johnson. My address is PO Box 2103, Batesburg-Leesville, South Carolina. My phone number is
1-803-532-4240. I look forward to seeing you and your store soon for some great shopping!

Alberta Canada weather, July 2020

I love so much about Farmer's Almanac, but the weather predictions are not among them. It is July 18, in Edmonton, Alberta, Canada and a grim, cloudy, soon-to-be-rainy day it is. Like nearly every day this summer. I have a big sweater on, and slippers, because it's cold. We've opened our windows in the house only a handful of times this "summer." I don't know if we've broken any low temp records, but it's been cold, rainy, and awful. I like your version better, but that ain't here.

Not sure about eastern Canada

Not sure about eastern Canada, but these predictions are out to lunch for the west. It’s been a terrible summer so far. As for Canada day being hot? Haha! Try rain, storms and below average temps. The long range forecast is also straight crap weather.

Date and Month is wrong

We are in June-18th 2020 NOT May 29th , so our forcast for today is wrong and any other day if you dont change it ,, Newfoundland Canada
