The live forecast above shows Kingston’s current conditions. Because the city sits on the northeast shore of Lake Ontario, the lake moderates temperatures year-round — keeping winters milder than inland towns and summers slightly cooler. Checking the hourly and 7-day outlook helps plan around these shifts.
What makes Kingston’s weather different from the rest of Ontario?
Kingston’s position on Lake Ontario creates a microclimate that acts as a thermal buffer. Winter lows average around -10.8°C, several degrees warmer than Ottawa or Montreal, while summer highs hover near 25°C. The same lake triggers lake-effect snowbands, often making the kingston weather radar the fastest way to see when bands are forming.

How do Kingston’s seasons affect your daily plans?
Spring and fall bring rapid changes — one day feels like summer, the next like winter — so the kingston weather 14 day forecast helps spot longer trends before they arrive. Summer humidity is moderate compared to Toronto, and winter snowfall averages about 160 centimetres. The kingston weather 7 days view (sometimes listed as kingston weather network 7 days) gives a reliable snapshot for the week ahead.
What is the best time to visit Kingston?
Late spring (May–June) and early autumn (September–October) offer the most comfortable weather — warm days, low humidity and fewer lake-effect surprises. July and August are pleasant but can feel humid, while winter appeals to anyone who enjoys snow and quiet lake views.
Does Kingston get a lot of snow?
Yes — roughly 160 cm per year, much of it from lake-effect bands off Lake Ontario. Snow can arrive suddenly, so checking the kingston weather hourly forecast during winter helps avoid driving into a whiteout. The kingston weather tomorrow view is especially useful before a commute.
Why does Kingston feel colder than the temperature suggests?
The open lake generates a steady wind off the water, especially in winter and early spring. This wind chill can make the air feel 5–10°C colder than the actual kingston weather celsius reading, so layering is key even on days that look mild on paper.
