The climate of Castlegar can be described as humid continental with four distinct seasons. The weather here is quite comfortable for travellers: the city is sheltered by mountains, which softens sharp temperature fluctuations and strong winds. Overall, the region is characterised by warm, sunny summers and snowy, moderately frosty winters.

The summer months, especially July and August, delight tourists with warmth: average daytime temperatures reach +25°C, and the number of rainy days is kept to a minimum. This is the ideal time for outdoor activities. In winter, from December to February, the thermometer drops on average to -6°C...-9°C. This period sees the highest number of days with precipitation, creating excellent conditions for winter sports and enjoying snowy landscapes.

Spring and autumn in Castlegar are transitional periods with cool and changeable weather. During these seasons, the number of wet days increases, so travellers should ensure they have waterproof clothing. Nevertheless, even in the off-season, the city retains its charm, offering tourists the chance to see nature awakening in spring or colourful leaf falls in autumn.

The climate in Castlegar is distinguished by distinct seasonality, offering travellers contrasting weather conditions depending on the time of year. The coldest period is traditionally the winter months, especially February and January, when average night-time temperatures drop to -9.5°C. Conversely, the peak of warmth occurs in mid-summer: July and August delight with stable and pleasant weather, making this season the most popular for tourism.

Winter here is genuine and frosty: from December to February, thermometer readings rarely rise above -2°C even during the day, while at night they steadily hold in the range of -8°C to -9°C. Spring arrives gradually, starting with a cool March, but by May the air warms up to a comfortable +15°C during the day, marking the beginning of the warm season.

Summer in Castlegar can be described as moderately warm, without extreme heat. In July and August, daytime temperatures reach an average of +25...+26°C, which is ideal for active outdoor recreation. However, significant daily temperature fluctuations should be taken into account: warm days are followed by rather fresh nights when the air cools down to +12°C, so even in summer, tourists are advised to carry a light jacket for evening walks.

The climate of Castlegar is characterised by a noticeable difference between the wet winter period and the dry summer. The highest frequency of precipitation is observed during the cold season. The record holder is January, when an average of about 19 days with precipitation is recorded. Given the freezing temperatures in the winter months (averaging from -2°C to -9°C), precipitation here most often falls as snow, creating a stable snow cover.

The spring months, especially April and May, remain quite humid: tourists should be prepared for rain on more than half the days of the month (about 16–17 days). However, the intensity of this precipitation is usually low, often taking the form of short-term rains or drizzle, alternating with clear spells.

Summer is a distinct dry season, which is perfect for travel. July and August are the driest months of the year: the number of days with precipitation drops to a minimum (about 7 days), and the volume of falling moisture is only 1 mm. This is the most comfortable time for walks and active recreation in the fresh air.

With the arrival of autumn, the weather gradually changes. September and October still retain relatively comfortable conditions, but by November precipitation increases sharply again (up to 17 wet days), and its volume reaches winter levels (4 mm). At this time, rain begins to give way to snow, preparing the city for winter.

When packing for Castlegar, it is important to consider the distinct seasonality of this Canadian region. Winters here are frosty and snowy, with an average temperature of about -6°C, so between November and March, you will definitely need high-quality thermal underwear, a warm down jacket, a hat, a scarf, and gloves. Given the large number of days with precipitation in the winter months (up to 19 days in January), you should ensure you have waterproof and insulated shoes with non-slip soles to feel comfortable during walks.

Summer in Castlegar, on the other hand, delights with pleasant warmth: in July and August, the air warms up to +26°C, which is ideal for outdoor activities. For this time of year, pack light, breathable clothing, sunglasses, and sunscreen, as the sun can be quite strong. However, even in summer, nights can be fresh (temperatures drop to +12°C), so a cosy hoodie or fleece jacket in your suitcase will certainly not go amiss.

Spring and autumn are distinguished by changeable weather and frequent precipitation, so the best solution is the layering principle, allowing you to remove or put on items depending on the situation. Be sure to take a reliable raincoat, a windproof jacket, and possibly an umbrella. Regardless of the season, for a trip to Canada, you will need comfortable, broken-in trekking shoes or sturdy trainers, as exploring the city and its picturesque surroundings involves a lot of walking.
