The number-one reason people retire to St. George is the weather — and unlike most sites, we've built this page from real historical climate data, not marketing copy. Here's exactly what to expect each month, so you can decide if Southern Utah's high-desert climate is right for your retirement.
St. George sits at about 2,800 feet in Utah's Mojave-Desert corner — the warmest, mildest climate in the state. Expect roughly 300+ days of sunshine a year, hot dry summers, and famously mild winters. Annual precipitation is just 7.4 inches, most of it in brief winter and late-summer bursts.
Figures below are averages computed from recent historical daily records (Open-Meteo), rounded to whole degrees Fahrenheit and inches of precipitation.
| Month | Avg High | Avg Low | Precip |
|---|---|---|---|
| Jan | 52° | 35° | 1.72" |
| Feb | 57° | 36° | 1.32" |
| Mar | 64° | 42° | 1.58" |
| Apr | 78° | 51° | 0.21" |
| May | 87° | 62° | 0.02" |
| Jun | 98° | 73° | 0.05" |
| Jul | 106° | 80° | 0.26" |
| Aug | 99° | 76° | 0.50" |
| Sep | 95° | 68° | 0.37" |

| Nov | 60° | 39° | 0.77" |
| Dec | 56° | 36° | 0.43" |
This is why snowbirds come. Daytime highs sit in the low-to-mid 50s (Jan averages a 52° high, 35° low), with abundant sun and only occasional light frost. You can golf, hike and play pickleball outdoors all winter — a rarity anywhere else in Utah.
March–May and September–November are near-perfect: highs in the 70s and 80s, low humidity, cool evenings. Most retirees call these the best months to be outside in Southern Utah.
Summers are genuinely hot — Jul averages a 106° high — but it's a dry heat with cool mornings and low humidity. Retirees adapt by golfing early, enjoying air conditioning midday, and heading to nearby high country (Pine Valley, Cedar City, Brian Head) which is 15–25° cooler.
If you want warm, dry, and sunny with real winter relief and a hot but manageable summer, St. George is one of the best climate matches in the West. If you prefer four distinct seasons with cooler summers, look at Cedar City, 50 minutes north and 2,000 feet higher.
St. George gets roughly 300+ days of sunshine per year, among the sunniest in Utah, thanks to its low-elevation Mojave-Desert location.
Mild. Jan averages a high near 52°F and a low near 35°F, with abundant sun and only occasional light frost — you can golf and hike outdoors all winter.
Hot but dry. Jul averages a high around 106°F with low humidity. Retirees golf early, use AC midday, and escape to cooler high country nearby.
Rarely and lightly. St. George averages only about 7.4 inches of total precipitation a year, and measurable snow is uncommon and short-lived, unlike higher-elevation Cedar City or Brian Head.
