Thunder Bay blackflies
I live in Thunder Bay. To be honest with you, last summer was so dry there were next to no blackflies in the summer. Blackflies breed in shallow creek beds left by rain or significant snow melt. We did not get much snow this year comparatively. Lakes will be low again this year too. You will need to worry more about the mosquitoes than blackflies. Late June or early July is best. The dragonflies are out and they love eating both!
Thunder Bay Forecast
I live in Thunder Bay and our weather is much different than Southern Ontario's weather. We are always a lot colder where I live and our January this year set some records for being warmer than normal. February on the other hand brought some real frigid temperatures {-40's} which might have also set some records. I also agree that we shouldn't be grouped in with Southern Ontario as their temps. are usually warmer.
Summer Holidays
I am trying to decide the best time for a two-week “camp” rental near Thunder Bay this summer. Your forecast predicts June having above normal temps but that’s the worst black fly season. What weeks might you suggest in July? Thanks, friends swear by this Almanac.
Ontario forecast (northwestern)
When giving forecasts for the Thunder Bay Area you can’t lump us together with southern Ontario. The farthest to the south you can include with Thunder Bay Area would be Terrace bay or at the most marathon, All though it’s usually warmer in marathon then any other area around the top of superior. Maybe look at updating the long rage forecasts in smaller zones for the future.
That spring feeling!
Hi there, I’m live 45 minutes north of Toronto and I am so done with winter! I can’t wait to get back into my garden. I was wondering, when can we expect to start feeling that spring weather? When the sun feels warmer, we can see the grass again, and the birds are singing!

Any Blizzard or bad storm due in Jan or Feb?
I want to book a week off work in Jan or Feb, especially if there will be a big dumping of snow; so then I can avoid the drive to work. So, what week looks good for a potential stay at home week? (I live in the north Toronto GTA)
Snowcation
Hi, Ann Marie: While there will be plenty of snowy periods in January and February, the only “snowtime” that really stands out for us right now is the first week of January. It’s hard to say whether this will be a sustained dumping, though! Thanks for asking and have a nice week off, whenever it is!
What is considered Southern
What is considered Southern Ontario region is the problem for many. The weather in Windsor and Barrie are 2 different worlds. For instance, Barrie might get a foot of snow, while in Windsor-Essex at the same time, it could be sunny and 50F degrees.
