Weather in Toronto

Stay up to date with the latest weather conditions in Toronto. Below you will find current data, forecasts, and useful weather charts to make your stay in Canada as comfortable as possible.

The climate in Toronto is characterized as moderate continental, with four distinct seasons. This means travelers can expect significant temperature fluctuations throughout the year, ranging from cold winters to warm summers. The city experiences a noticeable influence from the Great Lakes, which somewhat moderates extreme temperatures, but overall, the weather corresponds to its geographical location.

Winters in Toronto are generally cold, with average temperatures in January and February below zero (around -3.2°C and -2.3°C respectively), often accompanied by snowfall. Spring arrives gradually, with temperatures rising from March to May. Summer, especially in July and August, is warm and pleasant, with average temperatures around 22°C and highs reaching 25-26°C. Autumn brings coolness, preparing the city for the winter season, with a gradual decrease in temperature from September to November.

Regarding precipitation, it is distributed quite evenly throughout the year, averaging 2-3 mm per month. The number of days with precipitation is also relatively constant, ranging from 8 to 14 days per month. This means that, regardless of the season, it is worth being prepared for possible precipitation, whether it be rain or snow in winter. Overall, the weather in Toronto offers a diverse experience depending on the season, allowing you to choose the most comfortable time for your trip based on personal preferences.

Toronto observes a significant annual temperature variation, characteristic of a continental climate. The coldest months are traditionally January and February. In January, the average temperature is -3.2°C, with nighttime lows potentially dropping to -6.2°C, and daytime highs rarely rising above -0.2°C. February is slightly warmer, with an average temperature of -2.3°C, a minimum of -5.9°C, and a maximum of 1.2°C. Conversely, the peak of summer heat falls on July and August. In July, the average temperature reaches 22.1°C, with daytime highs around 25.8°C and nighttime lows around 18.4°C. August is also very warm, with an average temperature of 21.5°C, a maximum of 25.0°C, and a minimum of 18.0°C.

The summer months in Toronto, from June to August, offer pleasantly warm weather, ideal for walking and outdoor activities. Daytime temperatures consistently stay above 20°C, reaching an average of 22-26°C, while nights remain comfortable with temperatures of 15-18°C. The winter period, from December to February, is characterized by frosty weather. Average daytime temperatures often hover around zero or slightly below, and nighttime frosts are a common occurrence, with temperatures dropping to -6°C and lower. Temperature differences between day and night throughout the year are moderate, usually amounting to 5-8°C, which ensures relatively stable conditions during the day, though still noticeable.

The nature of precipitation in Toronto changes depending on the time of year. In winter, from December to February, and often in early March, when average temperatures stay below zero, the main type of precipitation is snow. For example, in January (3 mm) there are about 11 days with precipitation, and in December (3 mm) – 13 such days. With the arrival of spring, in March (2 mm, 11 days with precipitation) it gradually gets warmer, and by April (3 mm, 14 days with precipitation) and May (2 mm, 10 days with precipitation), snow is completely replaced by rain.

Summer months in Toronto, such as June (3 mm, 11 days with precipitation), July (3 mm, 12 days with precipitation), and August (2 mm, 11 days with precipitation), are characterized exclusively by rains. Given the moderate total amount of precipitation, these will most often be periodic, possibly short-lived showers, rather than prolonged downpours. In autumn, in September (2 mm, 8 days with precipitation) and October (3 mm, 12 days with precipitation), rains also predominate.

As winter approaches, in November (2 mm, 12 days with precipitation), when the temperature drops significantly, the first snowfalls are possible alongside rain. Although the monthly amount of precipitation in Toronto is small and fluctuates within 2-3 mm, the frequency of its occurrence varies. The highest number of days with precipitation falls in April (14 days) and December (13 days), while September is the month with the fewest such days — only about 8. This means that the probability of precipitation exists all year round, but its nature and frequency change, which is useful to consider when planning a trip.

When planning a trip to Toronto, it is important to consider its four distinct seasons, each requiring a different approach to wardrobe selection. Since the weather can be changeable, the best strategy is the principle of layering. This will allow you to easily adapt to temperature changes throughout the day, which can be noticeable even within a single season. Regardless of the time of year, comfortable walking shoes are your main ally for exploring the city. Also, considering that precipitation is possible in any month (averaging from 8 to 14 days with precipitation), a compact umbrella or a light waterproof jacket will be a useful addition to your luggage.

For the winter months (from December to February), when average temperatures hold around -3.2°C to 0.4°C and often drop below zero, as well as for early spring (March) and late autumn (November), you will need a warm winter jacket or coat, a hat, gloves, and a scarf. Do not forget warm sweaters, fleece jackets, and perhaps thermal underwear, especially if you are sensitive to the cold or plan long walks. Waterproof and insulated footwear will be very handy, as precipitation at this time often falls as snow or freezing rain.

In the summer months (June-August), the weather in Toronto is warm, with average temperatures around 18-22°C. Pack light clothing: t-shirts, shorts, dresses, sundresses. However, evenings can be cool, so a light sweater, cardigan, or windbreaker will come in handy. Sunscreen, sunglasses, and a hat are mandatory for protection from the summer sun. For the spring months (April-May) and early autumn (September-October), when the temperature is more moderate (from 6°C to 18°C), a combination of t-shirts, long-sleeved shirts, jeans or trousers, as well as a mid-season jacket or raincoat, is ideal. During these periods, do not forget an umbrella, as rains are still likely.
