Punta Arenas has a subpolar oceanic climate, marked by cool, stable temperatures, high humidity, and persistent winds. Summers (December to February) are short and cool, with average highs of 14–16°C and lows of 5–8°C. Even at the warmest, daytime temperatures rarely exceed 18°C, though record highs can reach up to 28°C. Sunshine is most abundant in summer, with up to 7–8 hours per day and daylight lasting over 16 hours at the solstice. Despite the long days, strong winds – often exceeding 20 km/h and sometimes reaching 130 km/h – are a defining feature, especially downtown, where ropes assist pedestrians during gusty periods. The sea remains cold year-round, with summer temperatures of 9–11°C, making swimming suitable only for the hardy.
Winters (June to August) are cold and cloudy, with average highs of 4–6°C and lows around -1 to 1°C. Snow is common but rarely heavy, and frost is frequent, though temperatures seldom drop far below freezing due to the ocean’s moderating effect. Rain and snow are possible throughout the year, with annual precipitation around 380–400 mm, evenly distributed but peaking slightly in April and May. Cloud cover is frequent, and winter days are short, with as little as 2–3 hours of sunshine and under 8 hours of daylight in June. Relative humidity is high (around 80–85%), and the Patagonian climate is famously unpredictable, so visitors should always be prepared for sudden changes. Punta Arenas is also notable for its exposure to high UV radiation due to the thinning ozone layer, especially in spring and early summer.
