San Jose Packing List — What to Pack for Every Season
San Jose packs very differently from coastal Bay Area cities. Summers hit 89–95°F with zero fog relief — plan for real heat. Winters bring 8 rainy days per month with cold foggy mornings that warm into mild afternoons. Year-round layering and waterproof footwear (Nov–Mar) cover most of what this city needs.
By Season
41–62°F
Winter (December–February)
San Jose winters are rainy and foggy with cold mornings (41°F) that warm to mild afternoons (57–62°F). December and January each see 8 rainy days. Layering is essential as the marine layer often burns off by noon.
- Waterproof ankle boots
- Light rain jacket
- Cashmere or merino layers
- Compact travel umbrella
47–76°F
Spring (March–May)
Spring transitions from rainy and cool (66°F highs in March) to dry and warm (76°F in May). Rain tapers off sharply — March has 7 rainy days but May only 2. Santana Row's outdoor dining becomes fully comfortable by late April.
- Light cardigan or zip fleece
- Versatile sneakers
- Sunglasses
- Crossbody bag for Santana Row
59–89°F
Summer (June–August)
San Jose's inland position means summers reach 83–89°F — noticeably hotter than San Francisco and without coastal fog relief. July and August have zero precipitation. The Los Gatos Creek Trail and outdoor venues like SAP Center require real sun protection.
- Lightweight breathable tops
- SPF 50+ sunscreen
- Wide-brim hat
- Reusable insulated water bottle
46–84°F
Fall (September–November)
September stays hot at 84°F before cooling steadily toward November's 66°F highs. October is pleasant but the rainy season returns in November (6 rainy days). Downtown San Jose's flat blocks are comfortable for walking in this transitional weather.
- Light jacket or denim jacket
- Versatile ankle boots
- Layers for cool evenings
- Compact umbrella (November)

General Packing Tips for San Jose
- 1.San Jose runs 10–15°F hotter than San Francisco in summer — if you're traveling between the two cities in July or August, pack for both a 89°F inland city and a 65°F coastal one.
- 2.Winter fog creates cold mornings (41°F) that often warm into 58–62°F afternoons — plan every December through February outfit around a peel-off mid-layer.
- 3.San Jose is car-oriented downtown; even short walks involve significant sun exposure on hot pavement in summer, so sunscreen and a hat are functional gear, not just accessories.
