🌱 Seed Starting CalculatorBurnaby's Growing Conditions — Maritime Climate and Elevation Effects
Burnaby Mountain — elevation matters
Burnaby Mountain rises to about 370 m above sea level — significantly higher than surrounding Metro Vancouver. This elevation means temperatures on and near the mountain run 2–3°C cooler than lower Burnaby or Vancouver. Gardeners at SFU or on the mountain slopes should treat their microclimate as roughly one zone cooler (Zone 7b) and add 1–2 weeks to all transplant dates compared to sea-level Burnaby.
Optimizing for the cloudy Pacific summer
Burnaby's summers are warm but frequently cloudy, with persistent marine influence. This is excellent for cool-season crops but limits heat accumulation for tomatoes, peppers, and corn. To maximize warm-season success: choose the sunniest spot in your garden (ideally south-facing), use raised beds (they warm faster), grow against a warm south-facing wall, and choose varieties rated for cool conditions. Black plastic mulch boosts soil temperature for heat-lovers.
What Burnaby grows superbly
Burnaby's maritime climate is ideal for leafy greens, brassicas, root vegetables, alliums, and berries. Kale, chard, broccoli, cauliflower, Brussels sprouts, leeks, carrots, beets, and garlic all excel. Strawberries, raspberries, and blueberries are among the most reliable crops in the lower mainland. The long mild fall allows for extended harvests well into November — brassicas and root vegetables sweeten after light frosts.

Frequently Asked Questions
What is the last frost date in Burnaby BC ?
Burnaby BC's last frost date is March 15 (Zone 8a) for low-lying areas. Gardeners on Burnaby Mountain should add 1–2 weeks. Transplant frost-sensitive crops outdoors from May 1–15, when nights are reliably warm and soil temperatures have risen sufficiently for good root establishment.
What tomatoes grow best in Burnaby BC?
Choose varieties that set fruit in cool, cloudy conditions: Siletz (55 days), Early Girl (62 days), Stupice (60 days), Legend (68 days, blight-resistant), and Glacier (55 days). Cherry tomatoes (Sungold, Sweet 100, Juliet) ripen reliably. Plant against a south-facing wall or fence, or in a greenhouse for significantly better results. Avoid large beefsteak varieties.
Can I garden year-round in Burnaby BC?
Yes — low-lying Burnaby's Zone 8a climate allows year-round vegetable gardening. Kale, chard, leeks, carrots, parsley, and spinach grow through most winters. Plant fall brassica crops in August, peas in February, and spring broccoli transplants in March. Gardeners on Burnaby Mountain should use cold frames for winter production.
Does Burnaby Mountain change my planting dates?
Yes — Burnaby Mountain's elevation (up to 370 m) creates noticeably cooler conditions than lower Burnaby. Add 1–2 weeks to all frost-sensitive transplant dates, treat tomatoes and peppers as you would in Zone 7b, and use row covers more liberally in spring and fall. The view is spectacular, but the growing conditions are a grade cooler.
