May Weather in United States
Is May Right for You?
Advantages
- Peak spring weather with comfortable 26°C (79°F) highs and mild 14°C (57°F) lows - perfect for outdoor activities without summer's oppressive heat
- Cherry blossom season continues in northern regions through early May, with fewer crowds than April peak season
- Pre-summer tourism shoulder season means 20-30% lower accommodation rates before Memorial Day weekend pricing kicks in
- Optimal hiking and national park conditions - trails are clear of snow but summer crowds haven't arrived yet
Considerations
- Weather unpredictability - can swing from 14°C (57°F) to 26°C (79°F) within days, making packing challenging
- Spring rain averages 10 days with sudden afternoon showers lasting 30-45 minutes that can disrupt outdoor plans
- Memorial Day weekend (late May) triggers peak season pricing and crowds at popular destinations
Best Activities in May
National Park Hiking and Nature Tours
May offers perfect hiking conditions with mild temperatures averaging 20°C (68°F) during peak activity hours and clear mountain views. Snow has melted from most trails but summer heat hasn't arrived. Wildflower season is at its peak, and wildlife is active after winter. Perfect visibility for photography with crisp spring air.
Urban Food and Brewery Tours
May's mild weather makes walking food tours comfortable, while spring seasonal menus feature fresh ingredients. Outdoor dining patios reopen after winter, and craft breweries launch spring seasonal beers. Perfect temperature for 3-4 hour walking tours without overheating.
Coastal Whale Watching Expeditions
May is prime migration season for multiple whale species along both coasts. Gray whales, humpbacks, and blue whales are actively feeding and traveling. Calmer spring seas with 1-2 meter (3-6 foot) swells make for comfortable viewing. Water temperature warming brings increased marine activity.
Scenic Drive and Photography Tours
May offers exceptional visibility with clear spring air and dramatic cloud formations. Perfect lighting conditions with longer daylight hours but softer sun than summer. Mountain roads are accessible but not yet crowded. Spring foliage and wildflowers provide stunning photography opportunities.
River Rafting and Water Sports
Spring snowmelt creates optimal water levels for rafting - exciting rapids but not dangerous flood conditions. Water temperatures are refreshing rather than shock-cold, around 12-16°C (54-61°F). Perfect air temperatures for getting wet without hypothermia risk.
Historic City Walking Tours
Comfortable walking weather with 20°C (68°F) afternoons perfect for 2-3 hour exploration. Spring light enhances historic architecture photography. Tourist crowds are manageable before summer peak season. Many historic sites have extended spring hours but summer pricing hasn't started.
