Météo à Half Moon Bay en mars

Forum posters describe March as one of the most changeable months in San Francisco - it could be warm, cold or rainy, with morning lows typically in the mid-to-upper 40sF and afternoon highs in the low-to-mid 60sF. Posters are consistent that any lingering rain is generally the tail end of the rainy season, with the major winter storms usually done by late March, though posters note it doesn't necessarily turn warm either - even in a typical year, only 2-3 days in the back half of the month might bring genuinely warm weather. Posters consistently emphasize real block-to-block variability, with temperatures feeling 5-10 degrees different between a sunny and shady side of the same street, and a 70F day cooling down to 50F by night. Posters generally recommend serious layers plus a lightweight raincoat regardless of the specific forecast.
