Each month classified as peak (best balance of weather and value), shoulder (a step in either direction), or low season.
Why visit Tucson during Mar–Apr, Oct–Nov?
Excellent — desert wildflower bloom in March if there's been winter rain (poppies, lupine, brittlebush carpeting the foothills), comfortable hiking temperatures, dry sunny days. By late May highs hit 35°C+ and it's into early summer.
Shoulder season (Feb, May, Sep, Dec) trades a small weather concession for noticeably smaller crowds and softer prices — often the sweet spot for travelers who want flexibility.
Low season (Jan, Jun–Aug) is when prices fall hardest. Expect weather extremes (heat, humidity, cold, or rain depending on the destination) and reduced hours at some seasonal businesses, but the trade-off can be worth it if budget or solitude matters more than perfect conditions.
