Plan this trip
Each site opens on its own search: choose your dates there. A few open on their home page, where you type the place too.

Travel insurance
Check whether your bank card or home insurance already covers this trip.
If the trip needs a visa, the travel agent or visa centre usually sells the cover it asks for.
Mobile data (eSIM)
Your own plan's EU roaming may already cover this.
Renting a pocket Wi-Fi is the other common way to stay connected.
These are sites people in book with. Each opens in a new tab, on the site's own pages.
Month by month
No fare history for this route yet, so this ranking is climate and crowds only — the price column will fill in as the scanner collects.
| Month | Max °C | Rain days | Humidity | Sun h/day | Verdict | Why |
|---|---|---|---|---|---|---|
| Jan | 18° | 6d | 70% | 8.6h | good | 18C max, 6 rainy days |
| Feb | 18° | 5d | 71% | 9.0h | good | 18C max, 5 rainy days |
| Mar | 18° | 6d | 75% | 10.0h | okbusy | busier than usual |
| Apr | 20° | 2d | 74% | 10.9h | sweet spot | 20C max, 2 rainy days |
| May | 20° | 1d | 74% | 10.9h | sweet spot | 20C max, 1 rainy day |
| Jun | 22° | 0d | 76% | 11.5h | sweet spot | 22C max, 0 rainy days |
| Jul | 24° | 0d | 77% | 12.2h | good | 24C max, 0 rainy days |
| Aug | 26° | 0d | 78% | 11.5h | goodbusy | busier than usual |
| Sep | 25° | 1d | 77% | 10.6h | sweet spot | 25C max, 1 rainy day |
| Oct | 24° | 1d | 71% | 9.8h | good | 24C max, 1 rainy day |
| Nov | 21° | 3d | 66% | 9.2h | good | 21C max, 3 rainy days |
| Dec | 18° | 4d | 70% | 8.2h | good | 18C max, 4 rainy days |
Rain days are the days with at least 1 mm of rain, as a weather station counts them.
A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. It is flagged rather than scored down, and crowds alone never make a month “avoid”: that is reserved for weather worth skipping.
How busy it gets
Then and now
San Diego's November days now average 21.0°C, 1.7°C warmer than in 1981–1990. 3 of 12 months are clearly warmer.
