The climate in Jasper, located in Canada, can be described as subarctic, with distinct seasons. It is characterized by significant annual temperature fluctuations: very cold, snowy winters and short, cool or moderately warm summers. A distinctive feature is the low total precipitation throughout the year, while the number of days with precipitation remains relatively high, indicating frequent but light precipitation.

There are four clearly defined seasons in Jasper. Winter (from November to March-April) is long and frosty, with average temperatures significantly below freezing, often dropping to -10°C and lower, especially in December, January, and February. Summer (June-August) is short and relatively cool, with average temperatures around +7°C to +12°C, although daytime highs can reach +18°C. Spring (May) and autumn (September-October) are short transitional periods with rapid temperature changes. The highest amount of precipitation, although small (about 4 mm), falls in the summer months, while in winter it is predominantly snow.

The climate in Jasper is distinguished by a marked change of seasons and a significant annual temperature range. The coldest months are traditionally December, January, and February. During this period, average temperatures drop to between -12.3°C and -13.5°C, and night frosts can be even more severe, reaching, for example, -15.4°C in January, -17.4°C in February, and -16.1°C in December. The warmest period is considered to be July, with an average temperature of about +12.1°C. At this time, daytime highs can rise on average to +18.2°C, creating comfortable conditions for outdoor activities.

Winter in Jasper is characterized as frosty. From December to February, air temperature consistently stays below freezing. Daytime highs in these months fluctuate on average from -9.2°C to -10.8°C, and nightly lows, as mentioned earlier, can be significantly lower. The summer months, especially July and August, bring pleasant warmth, but without sweltering heat. During the day, the thermometer in July and August reads on average from +17.6°C to +18.2°C. However, nights even in summer remain quite cool: average minimum temperatures in June are +1.7°C, and in July and August about +5.5°C to +5.9°C. It is worth noting that Jasper is characterized by noticeable daily temperature fluctuations, especially in the warm season (from May to September), when the difference between daytime maximum and nighttime minimum readings often exceeds 10-12 degrees.

Precipitation is observed in Jasper throughout the year, but its total volume is quite low. The winter period, covering the months from November to April, is characterized by frequent but usually light snowfalls, which is due to low average temperatures. The average monthly precipitation in these months, as well as in May, is only about 2 mm. Despite this, the number of days with precipitation (mainly snow) remains significant, ranging from 14 days in January, March, and December to 16 days in April and May.

The summer months, particularly June, July, and August, bring a slight increase in total precipitation volume, reaching 4 mm per month. June stands out as the month with the highest number of days with precipitation – an average of 21 days, while in July there are about 19, and in August – 16. During this warm period, precipitation falls mainly as rain. In autumn, in September and October, precipitation volume is about 3 mm per month, with the number of days with precipitation holding at a level of 16. With the drop in temperature in October, both rain and early snowfalls are possible.

Thus, Jasper does not have a clearly defined dry or rainy season in the usual sense due to the low total amount of precipitation. However, in terms of volume, the summer months (June, July, August) can be considered the "wettest", receiving 4 mm of precipitation each. The least amount of precipitation (2 mm) falls from January to May and from November to December. It is important to note that precipitation, whether snow or rain, happens quite often in almost any month, so tourists should be prepared for changeable weather and have appropriate clothing with them.

When planning a trip to Jasper, it is important to be prepared for changeable weather and significant temperature fluctuations throughout the year. The key principle when packing your suitcase is layering. This will allow you to easily adapt to weather changes by adding or removing layers of clothing. Regardless of the season, be sure to bring comfortable, sturdy walking shoes, as the region lends itself to outdoor activities. Sunscreen and sunglasses will also come in handy, especially considering the potential high-altitude location and sun reflection off the snow even in cooler months.

The winter months (from November to March, as well as cold periods in October and April) in Jasper are characterized by low, often freezing temperatures, with averages significantly below zero. During this period, you will need: very warm, windproof, and waterproof outerwear (jacket and trousers), thermal underwear, fleece tops, warm sweaters, a hat, a scarf, and gloves or mittens. Pay special attention to footwear – it should be warm, waterproof, and have a good non-slip sole. Given the large number of days with precipitation (most likely snow), even if the volume is small, protection from moisture and wind will be very useful.

The summer months (June-August) and early autumn (September) bring milder weather, with average temperatures around +7°C to +12°C, however, evenings and nights can be cool, and the temperature can drop close to freezing, especially in June and September. It is recommended to bring a light but warm jacket (windbreaker or fleece), several sweaters or tops, long-sleeved t-shirts and shirts, as well as trousers. Even in summer, it is worth having a waterproof and windproof jacket with you, as rain, although not abundant in volume, happens frequently (up to 21 days a month). Shorts may come in handy during the warmest daytime hours of July and August, but long trousers will be a more versatile option.
