Summer peak — busy. Highs in the high 70s, but the busiest and most expensive time, with long lines at attractions and hotels that sell out. Book at least a month ahead.

Comic-Con — avoid. Late July. Downtown hotels sell out fast once Comic-Con's booking opens, and rooms near the Gaslamp get very expensive that week.
