Ontario's weather forecast for June has dropped, and it's coming in hot (and maybe a little stormy).

According to the latest long-range forecast from the Farmers' Almanac, Ontario's June weather is looking unpredictable, with perfect patio days and intense thunderstorms sweeping the province.

If you were sick of the heavy rainfall in May, there's bad news ahead as unfortunately, it won't be entirely going away next month either.

Here's what to expect so you can plan your outfits and weekend getaways.

The Farmers' Almanac predicts the month will start on a more mellow note, with skies slowly clouding over from June 1 to 3 — the cool before a gorgeous stretch of weather.

From June 4 to 7, the Great Lakes region will enjoy sunny, pleasant vibes. It's the perfect time to hit the trails, grab a patio drink, or finally break out those summer fits.

But don't get too comfortable. Things turn dicey from June 8 to 11, with unsettled weather rolling in. There will be sudden rain showers and maybe thunderstorms, so keep that umbrella close.

Luckily, it clears up again from June 12 to 15 with another round of prime summer weather.

June 16 to 19 sees skies gradually clearing, setting us up for...well, a dramatic twist.

From June 20 to 23, western Ontario could see dangerous thunderstorms. Yep, the kind that might have you cancelling BBQ plans and watching the sky light up.

Then, from June 24 to 27, showers and intense storms will target eastern Ontario before finally giving way to fair skies.

So whether you're team "sunshine and sandals" or "storm watch and sweatpants," June has a little something for everyone.

Stay weather-aware, Ontario — this month will be a wild ride!
