Campobello Island’s weather is shaped by the Bay of Fundy, producing cool summers, mild winters, and frequent fog. The live forecast above shows current conditions; expect sea breezes and rapid shifts, especially in spring and autumn.
What makes Campobello Island’s weather unique?
Campobello sits at the mouth of the Bay of Fundy, where cold ocean currents and tidal mixing create a microclimate. Summer highs rarely exceed 22°C, while winter lows hover near -8°C. Fog is common from May to August, often rolling in within minutes. This maritime influence keeps temperatures moderate compared to inland New Brunswick—check the Canada weather hub for regional comparisons.
How does fog affect travel and activities?
Fog reduces visibility to under 400 metres on roughly 40 days per year, mainly in July and August. It can delay ferry crossings to Deer Island or the mainland. If you’re driving, slow down and use low beams. For hiking or kayaking, morning hours are usually clearer than afternoon. The weather network campobello island page provides hourly fog forecasts, while weather warnings cover dense fog advisories.
Is Campobello Island windier than the mainland?
Yes. Exposed coastal areas see average wind speeds of 20–30 km/h, with gusts over 60 km/h during autumn storms. The bay funnels wind, so sheltered inland spots are calmer.
Does Campobello get snow?
Yes, but less than inland New Brunswick. Average snowfall is about 180 cm per year, with most accumulation from December to March. Sea-effect snow can add sudden bursts.
How does the weather affect wildlife viewing?
Fog and light drizzle often bring whales closer to shore, especially in August. Clear, calm days are best for birding at Roosevelt Campobello International Park.
