Explore Ottawa Through the Seasons
Ottawa experiences a humid continental climate with four very distinct seasons: warm summers, cold and snowy winters, and relatively short but vibrant transition seasons in spring and autumn.
Winter (December to February)
Winters in Ottawa are known for their freezing temperatures and heavy snowfall. Average lows in January drop to around -15°C (5°F), with snow accumulations often exceeding 200 cm (80 inches) per year. The city transforms into a true winter wonderland, ideal for seasonal activities. Visitors can enjoy the Winterlude festival and the iconic Rideau Canal Skateway — the world’s largest naturally frozen skating rink.
Quick Tip: Pack thermal layers, a heavy winter coat, waterproof boots, and warm accessories like gloves, hats, and scarves — absolute musts when visiting Ottawa in winter!
Spring (March to May)
Spring arrives gradually as the snow begins to melt and temperatures start to rise. March can still be cold, but by May, daytime temperatures average around 19°C (66°F). This season is known for its fluctuating weather and increasing daylight. In May, don’t miss the stunning displays of blooming tulips at the Canadian Tulip Festival in Commissioners Park.
Quick Tip: Dress in layers to adapt to changing conditions. Water-resistant footwear is useful during the snow melt, and don’t forget a jacket or umbrella — spring showers are common!
Summer (June to August)
Summers in Ottawa are generally warm and humid. Average daytime highs range from 23°C to 27°C (73°F to 81°F), but heatwaves can push temperatures above 30°C (86°F). Thunderstorms are common in July and August, often occurring in the late afternoon. Summer is a lively time in the city, with outdoor concerts, festivals like Canada Day and Bluesfest, and plenty of opportunities to explore parks and waterways.
Quick Tip: Bring sunscreen, lightweight clothing, a hat, and plenty of water to stay cool and protected during Ottawa’s hot spells.
Autumn (September to November)
Autumn is a beautiful season in Ottawa, offering excellent conditions for outdoor activities. As the temperatures gradually cool and the air becomes crisp, the foliage turns to vibrant shades of red, orange, and gold. September remains mild and pleasant, while temperatures steadily decrease through October and November. The first snowfalls typically arrive in late November, marking the transition into winter.
Quick Tip: Choose comfortable walking shoes and layered clothing to stay snug as temperatures drop, especially if you’re out leaf-peeping or hiking. And don’t forget your camera — Ottawa’s autumn scenes are absolutely stunning!

Thinking of Moving to Ottawa?
If you’re planning to move to Ottawa, the city’s four-season climate is something you’ll want to prepare for. While Ottawa is beautiful year-round, living here means adjusting to real seasonal changes that shape daily life.
For newcomers, the winter season can feel intense at first, but the city is well-prepared. Snow clearing is efficient, public transit runs year-round, and homes are built with effective heating systems. Most residents invest in winter tires, water-resistant down-filled jackets, and insulated boots. Over time, many residents embrace winter through activities like skating on the Rideau Canal, skiing, or attending the Winterlude festival. Even after work or school, people often enjoy evening walks in snow-covered parks, ice skating, or relaxing together at a cozy local café.
Spring and autumn are relatively short but stunning transition seasons. Spring can mean muddy commutes and unpredictable weather, while fall brings crisp air and spectacular foliage. These seasons add variety to the year and showcase Ottawa’s natural beauty. On weekends, many residents take advantage of the pleasant weather to stroll along tree-lined streets, explore local parks, or enjoy outdoor markets and seasonal events with friends and family.
Summers are warm, lively, and full of outdoor activities. Expect average highs in the mid-20s °C (70s–80s °F) with occasional humid heatwaves above 30°C (86°F). Air conditioning is common in homes and apartments, and there are plenty of opportunities to enjoy bike paths, riverfront parks, and outdoor festivals after work. During the long and balmy summer evenings, Ottawans enjoy walks, playing in local sports leagues, or having picnics along the Ottawa River.

Living in Ottawa means preparing for both cold winters and hot summers, but most newcomers find the adjustment manageable with the right clothing, housing setup, and seasonal habits.
