What to Wear in San Francisco in April

April in San Francisco is not the spring city visitors often expect — temperatures from 50°F to 64°F with about 7 rainy days, and the Pacific fog that gives the Golden Gate Bridge its iconic atmosphere keeps the city noticeably cooler and windier than any other major California destination in spring. Genuine mid-weight layers — a quality windproof jacket over a merino sweater and dark jeans — are required throughout the month, especially along the Embarcadero waterfront and at Crissy Field where the bay wind is relentless. The city's eclectic, layer-mandatory aesthetic makes San Francisco April dressing a skill worth mastering.

San Francisco in April defies typical spring expectations. While many regions warm up significantly, the Golden City maintains its characteristic cool embrace. Daytime temperatures generally hover between a mild 55-65°F (13-18°C), but evenings consistently drop into the chilly 45-50°F (7-10°C) range. The city’s famous microclimates mean one neighborhood might be sunny while another is shrouded in fog and wind, sometimes within blocks. While April is significantly drier than winter months, expect a chance of light rain showers, so a water-resistant layer is a smart addition. The key to comfort here is strategic layering. Think light sweaters, cardigans, a versatile medium-weight jacket (denim, leather, or a windbreaker), and long pants or jeans. Even on a sunny afternoon, a sudden gust of wind or fog rolling in can make you reach for that extra layer. Forget flip-flops; comfortable, sturdy walking shoes are non-negotiable for tackling San Francisco’s iconic hills and extensive urban exploration. A light scarf can also provide warmth and style without bulk, perfectly adapting to the city's dynamic conditions.
