British Columbia is ideally visited from May to October for Vancouver and Vancouver Island, or from December to April for Whistler skiing. Summer (June-September) offers the best conditions in Vancouver: surprisingly dry oceanic climate (40 mm/month in July), 18-22 °C by day, low humidity, often clear sky. All parks open (Stanley Park, Pacific Rim, Whistler in hiking and MTB mode), orca watching at peak (May-October), festivals galore (Vancouver International Jazz Festival in June, Celebration of Light in July, Pride in August).
May and September are the best compromises: reduced crowds, rates down 20-30%, still pleasant climate. May is particularly recommended for Butchart Gardens in Victoria (peak bloom). September offers a dry and stable climate, ideal for hiking and wildlife viewing.
Winter (December-April) is exceptional for skiing at Whistler-Blackcomb (2nd largest North American area, 3,307 hectares, 200 runs, snowfall 9-12 metres/year), but Vancouver is very rainy: 200 mm/month in December, 170 mm/month in January, near-constant grey sky. Preserved urban activities (museums, gastronomy, city life), snowshoeing on Mount Cypress/Grouse 30 min from downtown. Tofino becomes storm watching capital (winter storm viewing from oceanfront lodges, mid-November to February, unique experience).
Shoulder season (October-November, March-April) is less favourable: frequent rains, Whistler in transition (end MTB season in October, start ski season late November), orca watching at end of season. Prefer summer or winter for an optimal trip.
