Weather in London

Are you planning a trip or simply interested in the weather in the city of London? Here you will find the most up-to-date information on weather conditions and detailed forecasts.

The climate in London, Canada, can be characterized as temperate continental. This means the city experiences four clearly defined seasons, each with its own unique weather conditions. Travellers should expect significant temperature fluctuations throughout the year, ranging from warm summer months to cold winters.

Summer in London is usually warm and pleasant. Average temperatures in June, July, and August hover around +19°C to +22°C, with maximum values reaching +24°C to +26.5°C. This is a wonderful time for outdoor activities. Winters, by contrast, are cold, with average monthly temperatures in January and February around -2.5°C to -3.4°C, while minimum temperatures can drop to -6.4°C. Snowfalls are possible during the winter months.

Spring and autumn are transitional seasons. In spring, from March to May, there is a gradual warming from an average of +2°C to +14.6°C. In autumn, from September to November, the temperature smoothly decreases from a comfortable +18°C to a cooler +4.4°C. As for precipitation, it is distributed quite evenly throughout the year, averaging 2-4 mm per month, with the number of days with precipitation varying from 10 to 16 per month. This indicates that the likelihood of rain or snow (depending on the season) exists almost constantly, but heavy downpours or prolonged rains are not a characteristic feature of the climate.

The annual temperature progression in London (Canada) demonstrates a clear change of seasons with pronounced temperature contrasts. The coldest months are January, with an average temperature of -3.4°C and minimum values dropping to -6.4°C, and February, where the average temperature is -2.5°C, and nightly lows can also reach -6.4°C. Conversely, the peak of warmth occurs in July, when the average temperature reaches 21.9°C and daytime highs rise to 26.5°C, and August with an average temperature of 21.0°C and a maximum of up to 25.3°C. Thus, the annual range of average maximum and minimum temperatures is quite significant.

The summer months in London – June, July, and August – are characterized by pleasantly warm weather. Daily average temperatures during this period vary from 19.6°C in June to 21.9°C in July. During the day, the air warms up to a comfortable +24°C...+26.5°C, creating excellent conditions for outdoor recreation. Nights bring refreshing coolness: minimum temperatures in the summer months range from 14.9°C to 17.4°C. The difference between day and night temperatures in summer is quite palpable, amounting to approximately 8-10 degrees, which is typical for a continental climate.

Winter in London, spanning December, January, and February, brings frosty weather. Average temperatures during these months range from 0.1°C in December to -3.4°C in January. Nighttime temperatures consistently drop below freezing, reaching an average of -6.4°C in January and February. Daytime temperatures also often remain negative, especially in January, when the average maximum is -0.4°C. In December and February, there may be slight thaws during the day with temperatures just above freezing (up to +1.5°C...+2.7°C). Daily temperature fluctuations in winter are less pronounced than in summer but still amount to about 5-8 degrees.

Precipitation in London (Canada) is a fairly regular phenomenon throughout the year, and there is no distinct rainy season or dry period in the usual sense. The amount of precipitation is distributed relatively evenly, although there are some monthly fluctuations in both volume and frequency.

The nature of precipitation changes depending on the season. In the cold months, roughly from December to March, when average temperatures often drop below freezing (January: -3.4°C, February: -2.5°C, December: 0.1°C, March: 2.0°C with minimums down to -2.2°C), precipitation mainly falls as snow. With the arrival of warmth, from April to November, residents and visitors to the city mostly encounter rain. Considering that the monthly average precipitation is only 2-4 mm, it can be said that this is most often light or moderate precipitation, rather than heavy downpours or abundant snowfalls.

Looking at the details, April stands out as the month with the highest number of days with precipitation (16 days) and one of the highest figures in terms of volume (4 mm). Also, 4 mm of precipitation falls in June and August, but the number of "wet" days in these months is slightly lower (12 and 13 respectively). The lowest amount of precipitation (2 mm) and the fewest days with it (10 days) is characteristic of September, making it conditionally the "driest" month. In December, only 2 mm of precipitation falls as well, however, there are 14 days with precipitation (predominantly snow). In general, be prepared for the fact that precipitation in London can catch you in any month, as it occurs on average from 10 to 16 days monthly.

When preparing for a trip to London, Canada, it is important to consider the changeable nature of the local weather and the frequent, albeit not heavy, precipitation. The key principle for your wardrobe is layering. This will allow you to easily adapt to temperature changes throughout the day, which can be quite noticeable. An indispensable item will be a compact umbrella or a light waterproof jacket, as the likelihood of light rain (and in winter – wet snow) exists almost all year round, considering the 10-16 days with precipitation monthly. Do not forget comfortable shoes for walking, as London is conducive to exploration on foot.

If your trip falls during the winter months (from December to March), when average temperatures drop below freezing (down to -3.4°C in January), and minimums can reach -6.4°C, be sure to take a warm winter jacket, hat, scarf, gloves, and waterproof shoes, as precipitation at this time often falls as snow. For a summer visit (from June to August), when the weather delights with warmth with average temperatures from +19.6°C to +21.9°C and highs up to +26.5°C, light clothing, t-shirts, and shorts will be suitable. However, even in summer, a light jacket or sweater for cool evenings, as well as sunscreen and headwear, will not go amiss. And, of course, do not forget an umbrella – summer rains are not uncommon here either, although usually not heavy.

Spring (April-May) and autumn (September-November) in London are transitional seasons with a fairly wide temperature range. In spring, the temperature gradually rises from an average of +2°C in March to +14.6°C in May, and in autumn, conversely, it decreases from a comfortable +18.1°C in September to +4.4°C in November. During these periods, layered clothing is especially relevant: t-shirts, long-sleeve tops, sweaters, a fleece jacket, and a mid-season jacket, preferably with wind and moisture protection. Given that the number of days with precipitation remains significant (for example, 16 days in April), waterproof outerwear or a reliable umbrella will be your faithful companions.
