Tucson, AZ – Arizona’s sunny skies and unusually warm temperatures dominate the first full week of October, with Tucson experiencing near-triple-digit highs through midweek. Despite much of the country cooling off, the desert city will remain hot and dry, offering classic fall weather marked by bright, clear conditions and warm daytime highs.
According to the National Weather Service in Tucson, the mercury will climb steadily from around 91°F on Sunday to nearly 98°F by Wednesday, maintaining unseasonable warmth as the week progresses. Residents and visitors alike should take precautions during peak afternoon heat and strong sun glare, especially along key routes like Interstate 10.
The Unrelenting Desert Heat This October
This week, Tucson is set to experience some of its warmest October days in recent memory, with forecast highs as follows:
- Monday: 94°F with sunny skies and a light southeast breeze
- Tuesday: 97°F, hot and dry with strong afternoon sun causing heavy glare along I-10
- Wednesday: 98°F, very warm with a high UV index
- Thursday: 98°F, mostly sunny with continued high temperatures
- Friday: 99°F, hot with a slim 10% chance of late showers
The heat is accompanied by light, variable winds shifting southeasterly, reinforcing the dry air mass that keeps rain chances nearly zero. Despite the warmth, nights will be relatively mild, dipping near 65°F, allowing for comfortable outdoor evening activities like dining and walks.

Perfect Weather for Fall Activities Despite the Heat

As the week advances, subtle cooling is expected by late Thursday and through the weekend, but temperatures will persist in the upper 90s.
