Month by month from San Francisco
No fare history on SFO–SGU yet, so this ranking is climate and crowds only. The price column fills in as the scanner collects.
| Month | Max °C | Rain days | Crowds | Verdict | Why |
|---|---|---|---|---|---|
| Jan | 8° | 5d | 80 | ok | 8C max, 5 rainy days |
| Feb | 10° | 6d | 100 | ok | 10C max, 6 rainy days |
| Mar | 15° | 7d | 65 | goodbusy | busier than usual |
| Apr | 21° | 3d | 96 | sweet spot | 21C max, 3 rainy days |
| May | 26° | 2d | 65 | sweet spot busy | busier than usual |

| Dec | 10° | 5d | 80 | ok | 10C max, 5 rainy days |
Rain days are the days with at least 1 mm of rain, as a weather station counts them.
Crowds is a score out of 100 where higher is quieter. It counts public-holiday clusters in US as well as at Zion, which is why this table differs from the same one read from another country. A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. Crowds alone never make a month “avoid”: that is reserved for weather worth skipping.

|---|---|
| Quieter, still good |
early Oct to late Oct — Cooler temperatures and fall colors make it a pleasant time to visit.
early Nov to late Nov — Fewer crowds and mild weather offer good value for visitors.
