Best time to visit Tucson

Tucson is a city of two halves. March scores 97 and July scores 25 — a 72-point swing, which is the difference between a holiday and an endurance test. The month you pick matters more here than almost anywhere. 6 of the twelve months sit within ten points of the best, so there is more than one right answer.

June is the warmest month at 39.4 °C and December the coolest at 18.9 °C — a 20.5 °C spread across the year. 182 days a year top 30 °C, more than a third of the calendar, so heat is the baseline here rather than a season. 8 nights a year dip below freezing.

There is a real wet season here. July to August carry the rain — up to 17 wet days in a month — while March, April, May, June, October and November drop as low as 1. That 16-day gap is the biggest single difference between a good month and a bad one in Tucson, and it moves further than the temperature does.

Daylight runs from 10.1 hours in winter to 14.2 in summer, enough to notice on a sightseeing itinerary.

The three strongest months are March, November, February. The one to think twice about is July. Each month below has its own page with rainfall reliability, extremes, daylight and crowd levels.
