What June is like in San Diego
June brings June Gloom, the same marine layer as May, often a little thicker. Coastal mornings are gray and cool, and highs reach about 71F (22C) when the sun finally shows. Summer crowds start once school lets out, prices climb, and the San Diego County Fair opens at the Del Mar Fairgrounds. The ocean is starting to warm but is still brisk.
This month suits families with school-year limits, fair lovers, and travelers who do not mind cloudy mornings. It is not the month to count on bright beach days, especially early in the month. If sunny beaches matter most, wait for late July through September.
Make the most of June
What is especially good about San Diego this month.
San Diego County Fair
The big county fair runs at the Del Mar Fairgrounds from June into early July, with rides, fair food, livestock barns, and concerts.
Legoland and SeaWorld before peak
Early June, before most schools are out, is a good window for the theme parks with shorter lines than July.
Afternoon beach breaks
When the gray lifts in the afternoon, calm beaches like La Jolla Shores and Mission Bay are good for kids to play in the sand.
What to pack for June
- A warm layer for gray mornings on the coast
- Sunscreen and a hat for when the sun breaks through
- Comfortable shoes for a long fair day
- A light wetsuit or rash guard if kids want to swim
Our timing tip
Go to the county fair on a weekday afternoon and plan inland sightseeing for the mornings, when the coast is most likely to be gray.
