What May is like in San Diego
May is when the marine layer moves in. Locals call it May Gray: mornings on the coast are often cloudy and cool, and the sun may not break through until afternoon, if at all. Highs reach about 69F (21C), and it rarely rains. Inland spots like the Safari Park are sunnier and warmer. Crowds and prices are moderate until Memorial Day weekend.
This month suits sightseers, zoo and museum fans, and anyone happy with mild, soft weather at fair prices. It can disappoint people who picture sunny beach days, since the coast can stay gray for a week at a time. For reliable sun and warm water, pick August through October.
Make the most of May
What is especially good about San Diego this month.
Sunny inland days
When the coast is gray, head inland. The Safari Park in Escondido often sits in full sun while the beaches stay cloudy.
Shoulder season rates
Hotels by the water are cheaper than in summer, and the zoo and Midway are calm on weekdays before school lets out.
Cool hiking weather
Overcast mornings make Torrey Pines and the Cabrillo trails comfortable to hike, with no harsh midday sun.
What to pack for May
- A light hoodie or fleece for gray coastal mornings
- Sunscreen, since UV gets through the clouds
- Walking shoes for the zoo and Balboa Park
- A light scarf or layer for breezy evenings by the water
Our timing tip
Plan beach time for the afternoon, when the marine layer is most likely to burn off, and spend gray mornings at the zoo or inland.

Things to do in San Diego
San Diego Zoo
Go at opening; the animals are most active in the morning. Plan a full day.
Balboa Park
Seventeen museums, gardens, and Spanish Colonial buildings. Many museums close one day a week, so check.
La Jolla Cove
Sea lions, seals, and snorkeling. Best in early fall when the water is warmest.
Cabrillo National Monument
Point Loma views, tide pools at low tide in winter, and gray whale watching from December through March.
USS Midway Museum
A walk-through aircraft carrier on the bay. A hit with kids.
San Diego Zoo Safari Park
Open-range animal habitats in Escondido, about 45 minutes north.
Beat the crowds
- Avoid Comic-Con week downtown unless you are going. Stay in La Jolla or Coronado if dates overlap.
- Hit La Jolla Cove and Torrey Pines early in the morning. Parking fills fast by late morning in summer.
- Visit the zoo on a weekday outside school holidays.
- Choose September and October for summer weather without summer prices.
Know before you go
- The city runs fully year-round. Some Balboa Park museums close one weekday each week.
- Beach water quality advisories can close stretches of shoreline after rain, especially near the Tijuana River in the South Bay. Check before swimming.
- Santa Ana wind events in fall can bring heat and fire danger to the region.
