Afternoon humidity peaks at 85% between 2-4pm despite lower rainfall, making midday outdoor activities uncomfortable and requiring strategic timing

Essential Tips

What to Pack

Lightweight merino wool layers - morning temperatures start at 23°C (73°F) but afternoons reach 34°C (93°F), requiring easy layering system

SPF 50+ broad-spectrum sunscreen - UV index reaches 8 even in winter, with reflection from concrete increasing exposure in urban areas

Comfortable walking shoes with good arch support - expect 8-12 km (5-7.5 miles) of walking daily on varied terrain from city sidewalks to hiking trails

Light rain jacket or windbreaker - brief showers occur 10 days in January, typically lasting 20-30 minutes in late afternoon

Breathable cotton or linen clothing - avoid polyester in 70% humidity as it traps moisture and becomes uncomfortable during active sightseeing

Reusable water bottle (1 liter minimum) - dry air and walking requires consistent hydration, with public fountains available in most parks and attractions

Portable phone charger - GPS navigation essential for wine country drives and hiking trails, cold morning air drains batteries 20% faster

Light evening sweater - temperatures drop to 23°C (73°F) after sunset, comfortable for outdoor dining but requiring light cover

Wide-brim hat or cap - essential for afternoon outdoor activities with high UV exposure and minimal natural shade on many trails

Insider Knowledge

Most locals start outdoor activities by 7am in January to capitalize on cool morning temperatures before afternoon heat and humidity build after 2pm

Farmers markets on weekends offer seasonal citrus varieties unavailable in supermarkets - blood oranges, Meyer lemons, and Asian pears peak in January at 40-60% below grocery store prices

January is the only month many tech company campuses offer public tours due to holiday schedules - Apple, Google, and Facebook typically allow visitors with advance registration

Local wine harvest celebrations continue through January with many smaller vineyards offering tastings of just-bottled wines exclusively to visitors, not available for retail purchase

Avoid These Mistakes

Underestimating afternoon humidity - many tourists plan strenuous activities for 2-4pm when humidity peaks at 85%, leading to discomfort and dehydration

Not booking wine country activities in advance - January is peak tourist season and weekend tours sell out 2-3 weeks ahead, leaving visitors with limited options

Assuming all outdoor attractions open early - many parks and trailheads don't open until 8am, wasting optimal cool morning hours for hiking and photography
