Climate & Weather

Our landscapes might offer extremes but our weather is decidedly moderate. Cape Breton Island enjoys a temperate coastal climate that rarely dips too cold or gets too hot with the weather and temperature fluctuating throughout the day. Around here there’s a saying that often rings true: “If you don’t like the weather, wait five minutes.” You’ll often experience sun, wind, and clouds in the same day, so pack smart and dress in layers.
