Key takeaways

Month by month

Summer (late June through September) is the most reliable season for hiking and boat tours, with daytime highs typically in the mid-teens to low twenties Celsius. Spring (April–May) and fall (October) are cooler and wetter, with more variable trail conditions. Winter is genuinely cold and snowy, with average highs well below freezing from December through February.

Pack for layers, not a single forecast

Rain gear and warm layers matter even on days that start clear — coastal weather changes quickly, and exposed viewpoints and summits are noticeably colder and windier than town. See our hiking guide for trail-specific advice, and our rainy-day guide for indoor backup options if a stretch of poor weather sets in.

Fog is normal here, not a bad sign

The cold Labrador Current and the warmer Gulf Stream meet off this coast, which contributes to regular fog, especially in spring and early summer. It can obscure coastal viewpoints without meaning the day is a washout elsewhere — inland and forested trails are often unaffected.
