The climate in Duncan is characterized by its mildness and the absence of extreme fluctuations, making the city a pleasant place to visit almost year-round. The warmest period is traditionally July and August, when the average temperature stays around 19–20°C, with daytime highs reaching a comfortable 24–25°C. The coolest months are February and December, yet even then, there are no harsh frosts: average temperatures remains above freezing, around 3–4°C.

Summer in this region of Canada is moderately warm and very favorable for outdoor activities. At the height of the season, especially in August, the weather is pleasantly warm without sweltering heat, with daytime maximums around 24.8°C. Winter is quite mild, especially compared to the continental part of the country. Nighttime temperatures in the winter months drop only slightly below or stay near freezing (0.4–1.7°C), so instead of biting frost, you'll find a refreshing chill.

Travelers should be mindful of the significant daily temperature fluctuations, which are especially noticeable during the summer. Even on the warmest days, the air cools down quickly after sunset: the difference between the daytime high and the nighttime low is often around 10 degrees (for example, dropping from 24°C during the day to 14°C at night). Spring and autumn serve as gradual transition seasons, with temperatures slowly shifting from a cool 5°C to a more pleasant 13–16°C.

Precipitation in Duncan follows a distinct seasonal pattern, typical for this part of Canada. The wettest and most overcast period is winter. December and January see the highest number of precipitation days—averaging about 20 days per month. Given that the average temperature during this time stays just above freezing (+3...+4°C), this usually means steady rain, though sleet is possible, especially when nighttime temperatures dip to +1°C.

In contrast, summer is the dry season, the most favorable time for tourism. July and August are the driest months of the year, when the number of rainy days drops to a minimum (about 5 days), and the amount of precipitation becomes negligible (about 1 mm). This time is ideal for those who prefer sunny weather without sudden downpours.

The shoulder seasons—spring and autumn—show a gradual shift in weather. While rain is less frequent in May and June (11–13 days), humidity rises again with the arrival of autumn. By November, the number of rainy days jumps to 18, preparing the city for a damp winter. Travelers planning a trip during the off-season or winter should definitely bring a reliable umbrella and waterproof shoes.

When heading to Duncan, it’s important to account for the changeable nature of the local weather and be prepared for rain, especially if your trip falls between October and March. The best solution for a traveler is the layering principle. Pack T-shirts, light jumpers, and a fleece jacket that can be easily layered. This will keep you comfortable during both cool mornings and warmer afternoon hours.

Since winters are mild but wet, and the number of rainy days can reach 20 per month, a waterproof windbreaker, a quality raincoat, and a sturdy umbrella will be your best allies. Pay special attention to footwear: it should be comfortable for long walks and preferably waterproof. In summer, Duncan's climate becomes significantly drier and warmer, with temperatures reaching 24-25°C, so don’t forget light clothing made of natural fabrics, sunglasses, and sunscreen, though a light jacket for the evenings is still a good idea.
