Halifax’s climate is shaped by its coastal position and the influence of the Gulf Stream. Summers (June–August) are comfortably warm, with average highs of 22–24°C and cool nights around 13–15°C. Humidity can be high, but sea breezes keep conditions pleasant. Fog is common, especially in early summer, and the city enjoys up to 7–8 hours of sunshine per day during this period. Rainfall is moderate, with July and August among the driest months, though brief showers and thunderstorms can occur.
Winters (December–March) are cold, snowy, and often windy, but milder than inland Canada due to the Atlantic’s moderation. Average highs range from 0–3°C, with lows dipping to -8 or -9°C. Snow is frequent, with snow cover on about 85 days per year, but rain and thaw periods are also common. Winter storms can bring heavy snow, freezing rain, and strong winds. Spring and autumn are transitional, with spring starting cool and damp, gradually warming by May, while autumn brings crisp air, vibrant foliage, and increasing rainfall. Halifax receives about 1,400 mm of precipitation annually, distributed fairly evenly, but October and November are typically the wettest months. Winds average 13–18 km/h year-round, and fog can roll in at any time, especially in spring and early summer.
