Page, Arizona Weather in May 2026

May turns Page into full boat weather: highs climb to 26.9C/80.4F, nights soften to 13.3C/55.9F, precipitation stays low at 7mm across 2.4 rainy days, and 12.9 hours of daily sunshine push Lake Powell surface temperatures past 18C for the first time since October. The sandstone walls of Glen Canyon go copper at 5pm, cliff swallows nest in the Wahweap alcoves, and the pinyon-juniper woodland along Highway 89 turns almost too fragrant after rare late-spring showers.

Lake Powell boat rental season officially peaks May through September and Antelope Point Marina books its houseboat fleet solid through Memorial Day weekend. Alstrom Point 4WD road opens in full dry condition, Navajo guide operators run Upper and Lower Antelope tours from 8am to 5pm, and the Colorado River at Lees Ferry hits comfortable raft temperatures for full-day flatwater floats. Locals move dinners to sunset picnics at Waterholes Canyon overlook, and Big John's Texas BBQ opens its patio for the season.

Historical May data at Page show a 1.9C increase in average highs over the last decade and a 15 percent drop in precipitation, and 2026 arrives with Lake Powell elevation still recovering but ten meters higher than the 2022 May low. The National Park Service opened a second boat launch ramp at Bullfrog Marina up-lake for the 2026 season and expanded ranger patrols for the busier Memorial Day weekend, which falls on May 25 in 2026.

Travelers planning Page in May 2026 should book houseboats before March or plan mid-May weekdays for last-minute availability, reserve Antelope Canyon tours four weeks out, and start hikes before 9am to beat mid-day heat on exposed slickrock. Rainbow Bridge boat tour access remains year-round from Wahweap Marina, and 2026 Memorial Day weekend campground reservations at Lone Rock Beach must go through the recreation dot gov portal by early May.
