The Warmest Places in Canada: A Data-Driven Guide to Hot Spots North of the Border

When people think of Canada, they think of snow, polar bears, and apologizing. Fair. The country's average annual temperature is 1°C (34°F), which is genuinely cold by any standard.

But here's what the data actually shows: parts of Canada regularly hit 35-40°C (95-104°F) in summer. Canada recorded its all-time high at 49.6°C (121.3°F) in Lytton, BC in June 2021 — hotter than Las Vegas has ever been. Let that sink in.

I spent three months researching climate data from Environment and Climate Change Canada to find the warmest place in Canada, the warmest town in Canada, and all the hot places in Canada worth knowing about. I ranked them by average summer highs, annual frost-free days, and overall livability. Here's what the numbers say.

Getting Around

Canada is enormous — second-largest country on Earth. The warmest regions are concentrated in three areas:

1. Southern British Columbia (Okanagan Valley, Fraser Valley)
2. Southern Ontario (Windsor, Leamington, Niagara region)
3. Southern Alberta/Saskatchewan (Medicine Hat, Lethbridge)

Pro tip: If you're visiting BC's Okanagan, rent a car. Public transit between towns is nearly non-existent. The valley is 200 km long with wineries, beaches, and towns scattered along Lake Okanagan. A car isn't optional — it's the trip.

What to Do

The Warmest Places in Canada (Ranked by Data)

#1: Osoyoos, British Columbia

• Average July high: 33.2°C (91.8°F)
• Frost-free days: 152/year
• Canada's pocket desert

Osoyoos is officially the warmest place in Canada by average summer temperature. It sits in the northern tip of the Sonoran Desert — yes, Canada has a desert — and the landscape looks more like Arizona than anything you'd expect north of the 49th parallel. Osoyoos Lake is the warmest freshwater lake in Canada, regularly hitting 24°C (75°F) in summer.

What to do: wine tasting (Nk'Mip Cellars is Canada's first Indigenous-owned winery), swimming in the lake, hiking in the desert ecosystem, and the Osoyoos Desert Centre for a guided tour of this bizarre landscape.

#2: Lytton, British Columbia

• Average July high: 34.0°C (93.2°F)
• Holds the national heat record: 49.6°C (121.3°F)
• Sadly devastated by wildfire in 2021, rebuilding

Lytton regularly records the highest temperatures in Canada. It sits at the confluence of the Fraser and Thompson Rivers, and the canyon geography traps heat. The town is small (population ~250) and was heavily impacted by the 2021 fire. It's being rebuilt, but visitor infrastructure is still limited. Worth knowing about for the data, but plan your trip around other destinations for now.

#3: Kamloops, British Columbia

• Average July high: 31.6°C (88.9°F)
• Frost-free days: 139/year
• Semi-arid grasslands

Kamloops is one of the most consistently hot places in Canada and has actual tourism infrastructure. The city sits in a valley where the North and South Thompson Rivers meet, creating a heat-trapping effect. Summers are dry and hot. Winters are cold but shorter than most Canadian cities.

What to do: Sun Peaks Resort (summer hiking, winter skiing), BC Wildlife Park, golfing (9 courses nearby), and river floating on the South Thompson.

#4: Penticton, British Columbia

• Average July high: 30.8°C (87.4°F)
• Frost-free days: 144/year
• Sandwiched between two lakes

Penticton is the warmest town in Canada that's also a genuinely great vacation destination. It sits between Okanagan Lake and Skaha Lake, giving you two beaches within walking distance. The Kettle Valley Rail Trail runs through town — a converted railway that's now one of BC's best cycling paths.

What to do: Float the Penticton Channel (2-3 hours from lake to lake on a tube), wine tasting (30+ wineries within 20 minutes), hiking, and the Penticton Farmers' Market on Saturdays.

#5: Oliver, British Columbia

• Average July high: 31.5°C (88.7°F)
• 300+ hours of sunshine in July
• Canada's "Wine Capital"

Oliver is 20 minutes north of Osoyoos and brands itself as the Wine Capital of Canada. It has 40+ wineries, desert hiking trails, and lake access. The Golden Mile Bench wine region here produces some of Canada's best reds.

#6: Windsor, Ontario

• Average July high: 28.5°C (83.3°F)
• Frost-free days: 165/year
• Southernmost city in Canada

Here's a fun geography fact: Windsor, Ontario is further south than parts of California. The city sits at the same latitude as northern California's wine country. It's the warmest city in Canada east of the Rockies and has the longest frost-free season in the country.

What to do: Walkerville District for craft beer and food, Point Pelee National Park (30 minutes south — the southernmost point of mainland Canada), and the Windsor Sculpture Park along the riverfront.

#7: Leamington, Ontario

• Average July high: 28.0°C (82.4°F)
• Frost-free days: 170/year
• "Tomato Capital of Canada"

Leamington has the most frost-free days of any place in Canada. It sits on Lake Erie and benefits from the lake's moderating effect. The Heinz ketchup factory put it on the map. Point Pelee National Park is right here.

#8: Medicine Hat, Alberta

• Average July high: 29.0°C (84.2°F)
• 330 days of sunshine/year
• "The Gas City"

Medicine Hat claims to be the sunniest city in Canada, and the data backs it up. Over 2,500 hours of sunshine annually. The summers are scorching, the winters are moderated by chinook winds, and natural gas is so abundant the city heats some sidewalks in winter. Rudyard Kipling called it the city "with all hell for a basement" because of the gas reserves.

#9: Kelowna, British Columbia

• Average July high: 30.0°C (86°F)
• Frost-free days: 130/year
• Okanagan's biggest city

Kelowna is where most people base their Okanagan trips. It has the airport, the infrastructure, and the beaches. Okanagan Lake Beach is one of the best urban beaches in Canada. Summer here is consistently hot and dry.

#10: Niagara-on-the-Lake, Ontario

• Average July high: 27.5°C (81.5°F)
• Frost-free days: 160/year
• Wine country with microclimate

The Niagara region benefits from the lake effect and the Niagara Escarpment, creating a microclimate that's warmer and more moderate than the surrounding area. Hence all the wine. This is Ontario's Napa Valley.

Honorable Mentions

Where to Eat

Since the warmest regions are wine country, the food scene punches above its weight:

Pro tip: In the Okanagan, most wineries have on-site restaurants. Tasting fees ($5-$15) are often waived with a bottle purchase. Hit 3-4 wineries before lunch and you've assembled a free tasting menu with $20 in wine.

FAQ

Q: What is the warmest place in Canada year-round? A: Victoria, BC has the mildest year-round climate (average annual temp of 10.4°C/50.7°F) because it rarely gets cold. But for summer heat specifically, Osoyoos and Lytton are the hottest. "Warmest" depends on whether you mean peak heat or consistent mildness.

Q: Does Canada actually get hot? A: Yes. Osoyoos regularly exceeds 35°C (95°F). Lytton hit 49.6°C (121.3°F). Medicine Hat gets 330 days of sunshine. Canada is cold in winter, but summers in the right places rival the American Southwest.

Q: What's the warmest town in Canada to live in? A: For retirees and snowbirds looking at year-round warmth: Victoria, BC or Osoyoos, BC. For hot summers specifically: Osoyoos. For the longest frost-free growing season: Leamington, Ontario.

Q: Is the Okanagan like Napa Valley? A: Similar climate and wine focus, but about 40% cheaper. Tasting fees are $5-$15 vs. Napa's $25-$75. Hotels and food cost significantly less. The wines are increasingly competitive — BC Pinot Noir and Riesling are winning international awards.

Q: When should I visit Canada's warmest places? A: July and August for peak heat. June and September for warm weather with fewer crowds. The Okanagan wine harvest happens in September-October, which is arguably the best time to visit.
