Is May Right for You?

Advantages

Perfect shoulder season weather - warm 32°C (90°F) days without brutal summer heat, comfortable for walking downtown areas and waterfront activities
Asparagus festival season - May is prime harvest time when local farms offer tours, U-pick experiences, and farmers markets showcase the region's agricultural heritage
Delta boating conditions are ideal - water levels stabilized, temperatures perfect for kayaking, fishing, and houseboat rentals before summer crowds arrive
Hotel rates are 25-30% lower than summer peak season, with excellent availability before Memorial Day weekend marks the start of tourist season

Considerations

Afternoon winds pick up to 24-32 km/h (15-20 mph) most days, making outdoor dining uncomfortable and affecting water activities after 2pm
Marine layer fog rolls in 40% of mornings, delaying outdoor plans until 10-11am and reducing visibility for photography
Pollen count peaks in May - severe for those with allergies to grasses and tree pollens, particularly valley oak and olive trees

Essential Tips

What to Pack

Light layers essential - temperature swings from 18°C (64°F) morning fog to 32°C (90°F) afternoon heat require adaptable clothing

Windbreaker or light jacket for afternoon winds that reach 24-32 km/h (15-20 mph), especially near waterfront areas

SPF 50+ sunscreen mandatory - UV index hits 8 and Central Valley sun reflects intensely off water and pavement

Closed-toe shoes for farm tours and walking on uneven agricultural terrain, even if weather seems sandal-appropriate

Allergy medication if sensitive to pollen - May peak season for valley oak, olive trees, and grass pollens

Light rain jacket for occasional brief showers - 10 rainy days average, usually light and short-duration

Hat with chin strap for Delta boat activities - afternoon winds make loose hats problematic

Cotton or linen clothing instead of polyester - 70% humidity makes synthetic fabrics uncomfortable and sticky

Insect repellent for Delta waterway activities - mosquitoes active near standing water areas

Comfortable walking shoes with good grip for downtown historic district tours on varied pavement surfaces

Insider Knowledge

Morning marine layer burns off by 10-11am most days - schedule outdoor photography and sightseeing for late morning rather than early morning starts

Locals eat lunch early (11:30am-12:30pm) to avoid the afternoon wind rush at outdoor restaurants - follow their lead for better service and calmer conditions

Gas up before heading to Delta areas - fuel stations sparse in waterway regions and prices can be 20-30 cents higher per gallon than downtown

Download offline maps for Delta exploration - cell service spotty in remote waterway areas, especially on islands and channels away from main routes

Avoid These Mistakes

Planning all activities for early morning thinking it's cooler - marine layer fog often delays outdoor plans until 10-11am, making late morning starts more practical

Booking outdoor dining for 2-4pm timeframe when afternoon winds make patios uncomfortable - lunch by 1pm or dinner after 6pm work better

Underestimating driving distances to Delta attractions - waterway routes wind considerably, adding 30-45 minutes to estimated straight-line GPS times
