Locked into a busy day? Here's the play.

–9am

Own the morning.The day-trip wave lands mid-morning; the headline sights before nine are effectively yours.

10–5

Go where the day-trippers don't.Away from the headline sights it stays manageable all day. Save the marquee ones.

5pm+

Take the city back.Day-trippers leave by early evening — the same squares empty out and the light is better.

On the busy days, the walk-up queues for the big sights are the biggest time-sink — a timed-entry ticket skips them, which is where a busy month is won or lost.

So is it worth it? →

Is June worth it in San Diego?

Peak weather and peak crowds — the classic trade-off; you pay for the season in queues, not in the weather. For better value, come in November or October.

Book beds and the big-ticket sights well ahead, and start your days by eight — in a month this full, the early hours are the only uncrowded ones.
