Best Time to Fly to California

When to fly to California depends on where in California you’re going. The state’s climate varies dramatically, so if you're looking for cheap flights to California, it's best to choose a city first and search flights during the off-season.
Peak Season:
The peak season for flights to California is the summer. Los Angeles, San Francisco, and Napa Valley greet summertime travelers with warm weather and dry days.

Off Season:
Winter is the low season for LA, Anaheim, San Francisco, and wine country. However, winter in San Francisco is when the ballet and opera seasons are in full swing. Wine country is also fun to visit in fall, when the wineries are in production, and spring, when the flowers are in bloom.
Find cheap flights to California

Purchasing tickets in advance is obviously the best way to get the cheapest rate. You can always try to wait until the day of the flight, but then you run the risk of it being booked. Do it as much as advance as possible if you want the cheapest rate.

Actually, research shows that the cheapest flights can often be found 6-8 weeks ahead of departure.

Finally, next time you post, you should definitely include your home airport :)
