May in St. George

Last call before summer heat arrives

May Weather

88°F / 57°F

Getting hot. Early mornings and evenings are pleasant, but midday sun is intense. Water activities become the main event by late May.

May is the ticking clock. Locals know that the window for comfortable all-day desert hiking is closing, and they squeeze every last trail out of this month. Temps push into the 90s by month's end, but mornings are still gorgeous, water season is fully open, and the IRONMAN brings electric energy to town.

Best Hikes (Go Early)

May hiking means early starts. Hit the trail by 7 AM and you'll have comfortable temps and soft morning light. By noon, the exposed trails are uncomfortably hot.

Lower Pine Creek Falls

Moderate — 4 miles, elevation gain through forestPine Valley Recreation Area, north of St. George

This hidden waterfall near Pine Valley is fed by late-season snowmelt and peaks in May. The trail follows a forested creek through ponderosa pines — a dramatic contrast to the desert below. The falls aren't massive, but the setting is lush and cool, making it an ideal escape from the warming valley floor.

The hike is about 4 miles round trip with moderate elevation gain through the pine forest. May is the sweet spot when water flow is strong and the trail isn't muddy. The higher elevation (6,500+ feet) keeps temperatures 15-20 degrees cooler than St. George.

Insider Tip

Combine this with a stop at the Pine Valley Heritage Center and a drive through the Pine Valley Mountains scenic route. The whole loop makes an excellent half-day escape from the heat.

Gunlock Waterfalls & Reservoir

Gunlock, about 20 minutes northwest of St. George

When the Santa Clara River runs high in May, the Gunlock waterfalls come alive. These cascades drop over basalt rock into swimming holes that locals have cherished for generations. The main falls are accessible via a short walk from the road — no real hiking required.

Gunlock Reservoir above the falls offers excellent kayaking and fishing in a quieter setting than Sand Hollow. The volcanic landscape here is unique — black basalt instead of red sandstone — and the drive through the Santa Clara River valley is beautiful.

Insider Tip

The best swimming hole is below the second cascade. Follow the social trail downstream from the main viewing area. Water levels vary dramatically — call Gunlock State Park to check before driving out.

Veyo Pool & Crawdad Canyon

Veyo, about 25 minutes north of St. George

Veyo Pool is a natural spring-fed swimming hole that's been a local institution for decades. The water stays a refreshing 65°F year-round, which feels perfect in May's heat. Beyond the pool, Crawdad Canyon offers a short adventure hike through a narrow volcanic canyon.

The pool area includes a rope swing, diving platforms, and a small snack bar. It's very much a locals' hangout rather than a polished resort — and that's its charm. May weekdays are the best time to visit before school gets out and summer crowds arrive.

Insider Tip

Crawdad Canyon is free to explore even if you don't pay for pool access. The short canyon hike is fun for kids and leads to interesting volcanic formations. Ask at the desk about conditions.

Events

May brings one of the biggest events of the year to St. George, along with the last of the comfortable outdoor festivals.

IRONMAN 70.3 St. George

Various locations — starts at Sand Hollow, finishes downtown

The IRONMAN brings thousands of athletes and spectators to town, and the energy is incredible even if you're not competing. The swim takes place at Sand Hollow Reservoir, the bike course winds through Snow Canyon and along the scenic Highway 18 corridor, and the run finishes in downtown St. George.

Spectating is free and there are viewing spots all along the course. The downtown finish line on Main Street is the most exciting — watching athletes cross the line is genuinely moving. Local businesses often run specials and the whole town has a festival atmosphere.

Insider Tip

The best spectating spot is at the Snow Canyon turnaround on the bike course. You get to see athletes twice (going and coming), the scenery is spectacular, and it's far less crowded than the finish line.

Water Activities

By May, water is the dominant theme. Every reservoir and swimming hole in the area is open and inviting.

Quail Creek — All Water Sports

Quail Creek State Park, Hurricane

May brings Quail Creek to ideal conditions — water temp in the high 60s to low 70s, reliable afternoon winds for sailing and windsurfing, and warm enough for swimming without a wetsuit. The reservoir supports powerboating, jet skiing, fishing, SUP, and kayaking.

The beach area at the south end is the most accessible for families. For a quieter experience, launch a kayak from the northern boat ramp and paddle into the sandstone coves. Fishing for largemouth bass is excellent in May as the fish move to shallows for spawning.

Tubing the Virgin River

Virgin River Corridor, through St. George

When May flows are right, tubing the Virgin River through town is a quintessential St. George experience. The put-in near the confluence park and the take-out at the southern bridge create a lazy 2-hour float through cottonwood-lined banks with red cliffs rising on either side.

This is strictly a flow-dependent activity — check the USGS gauge before inflating your tube. May flows of 150-300 CFS are ideal. Higher means too fast and technical, lower means you'll be dragging. Cheap tubes from Walmart work fine; bring shoes you can get wet.

Insider Tip

The Virgin River flow gauge is online at USGS. Bookmark it. Ideal tubing flow is 150-300 CFS. Above 400 CFS is too fast for casual tubing.
