Essential Tips

What to Pack

Lightweight long pants for evening - temperatures drop 10°C (18°F) from day to night, and locals dress up for dinner

SPF 50+ sunscreen - UV index reaches 8 even on partly cloudy days due to high elevation and clear air

Reusable water bottle (750ml+) - public fountains available but hydration critical as humidity stays low at 70%

Light cardigan or jacket - essential for air-conditioned restaurants and evening outdoor dining

Comfortable walking shoes with good grip - many sidewalks have steep grades up to 15% in downtown areas

Portable phone charger - using GPS and camera in bright sunlight drains batteries faster

Cash for farmers markets and food trucks - many vendors don't accept cards, ATM fees $3-5

Lightweight day pack - for carrying water and layers during temperature fluctuations of 11°C (20°F) daily

Polarized sunglasses - essential for driving in bright California sun and outdoor activities

Light rain jacket - brief afternoon showers possible 10 days per month, typically lasting 15-20 minutes
