The West Coast Trail and Pacific Rim National Park enjoy a maritime climate of mild winters and cool summers. Most precipitation occurs during the winter however storms can occur very often during the relatively drier summer months. The average temperature varies from about 6 C in the winter to 14 C in the summer. Be prepared for quick moving storms, fog banks, clear weather, rain, and cool temperatures. The logistical problem with the WCT is the shuttle between trailheads.
Some hikers do it before their hike, others do it after.
One can use the Quu'as West Coast Trail Group shuttle bus, the Juan de Fuca Express water taxi, or other operators listed in the Hiker's Preparation Guide. Hikers should be aware of cooler, cloudy, and wetter conditions during the summer than Victoria or Vancouver. Fog often develops overnight and comes onshore during the morning. However with the warming of the landmass, the fog often dissipates in the early afternoon. Clear, sunny weather can rapidly give way to approaching frontal systems with rain, low cloud, and cooler temperatures.
