Surrey’s 30-day outlook points to a typical late-autumn pattern for the Lower Mainland: alternating bands of Pacific rain and brief dry spells, with daytime highs near 10–12°C and overnight lows around 4–6°C. Check the live forecast above for daily shifts.
What drives Surrey’s 30-day forecast?
The long-range picture for Surrey relies on ensemble models tracking the jet stream over the North Pacific. When a strong ridge builds near the coast, the city sees drier, milder stretches; a trough often funnels series of wet systems inland from the Strait of Georgia. Neighbouring communities from Delta to Langley experience similar patterns, though the Fraser Valley can trap cooler air on calm nights.

How reliable are 30-day outlooks for Surrey?
Confidence in the 28 day weather forecast surrey remains moderate. Beyond ten days, model agreement often drops, so treat the 30-day outlook as a general tendency rather than a day-by-day guarantee. For hourly details on the near term, refer to weather surrey 14 days hourly; for the full month, surrey weather 30 days hourly offers more granular timing. The 21-day and 28-day forecasts at surrey weather 21 day forecast and 28 day weather forecast surrey hourly provide useful middle-range guidance.
Should I expect snow in Surrey this month?
Snow is rare in Surrey during a typical November. The city’s low elevation and marine influence usually keep precipitation as rain. Only if a cold Arctic airmass pushes into the Fraser Valley might flurries reach ground, but that’s unlikely in a 30-day window.
Does the Fraser Valley fog affect Surrey’s 30-day forecast?
Yes, dense fog can develop on clear, calm nights, especially near the river. The 30-day outlook may not capture these short-lived events, but the daily forecast in the live forecast above will highlight fog advisories when they arise.
