Most golfers arriving in St. George in May expect mild spring weather with comfortable temperatures all day — and that part is mostly true. What catches people off guard is how quickly the thermometer moves. Mornings can sit in the low 60s, which is nearly ideal, but by mid-afternoon the high reaches 85F, and the 24-degree daily swing means the vest you needed at 7 AM is a liability by noon.
The other surprise is the wind. May is actually the second-windiest month of the year here, averaging 12 mph at peak, which is firmly in the "moderate" range for club selection. Golfers expecting dead-calm desert air will find themselves rethinking distances on exposed holes. Tee off early, dress in layers you can shed, and don't underestimate what a consistent 12 mph crosswind does on St. George's canyon-framed layouts.
Book the earliest available tee time — 6 or 7 AM — to play the back nine before temperatures clear 80F, since the high hits 85F and the 24-degree daily swing means conditions deteriorate meaningfully as the morning progresses. Weekday morning slots in May fill faster than many visitors expect given the peak-season badge, so lock in tee times at least a week out.

April and May share the same precipitation profile — both sit at just 3 rainy days — so the shift into May is really about heat, not moisture: highs jump 8F from April's 77F to May's 85F, and lows rise a full 9 degrees, meaning cooler morning rounds are still pleasant but noticeably warmer than the month before. June then accelerates hard, adding another 14F to the high (reaching 99F) while dropping to just 1 precipitation day, making May the last month where afternoon play remains genuinely comfortable. Wind stays nearly constant across all three months, hovering between 11.4 and 12 mph peak.

May's average high of 85F is warm but manageable if you start early — early morning temperatures will be closer to the low of 61F, giving you a more comfortable window before the high of 85F is reached. The real concern is the tail end of afternoon rounds, when temperatures are fully at their daily peak and shade on desert-style courses is limited.
May is the second-windiest month of the year in St. George, with peak winds averaging 12 mph — enough to consistently affect club selection and ball flight. The wind tends to pick up through the afternoon, which is another reason morning tee times give you the most predictable conditions.
