Moab

Here's the thing about Moab that surprises most people: it's a high-desert town where 10.9 hours of daily sunshine is the norm, yet the real trick isn't finding sun—it's finding the sweet spot between scorching heat and bone-chilling cold. The annual average high sits around 21.6°C (71°F), but that number masks wild swings. You'll want March, April, May, and October if you're actually planning to enjoy being outside without melting or shivering.

Spring (March through May) is when Moab wakes up. March can still bite—nights drop near freezing—but days warm to around 15–18°C (59–64°F), perfect for hiking without overheating on the red rock trails. April is the sweet spot: highs settle around 20–23°C (68–73°F), the desert wildflowers start popping, and the crowds haven't yet hit the wall-to-wall summer levels. May nudges toward 25°C (77°F), which is still manageable, though you'll notice more tourists and higher accommodation prices. October mirrors April's magic—clear skies, highs around 22–24°C (72–75°F)—but with fewer people and that golden-hour light that makes photography addictive. The difference? Spring feels like the town's coming alive; fall feels like everyone's secretly in on the best-kept secret.

Summer and winter are the painful months. June through September sees temperatures soar past 35°C (95°F) regularly, with July and August hitting 38–40°C (100–104°F). The heat isn't just uncomfortable; it shortens your active hours to dawn and dusk, and many outdoor operators run limited schedules. Winter (November through February) brings cold nights—sometimes dropping below freezing—and occasional snow that can close canyon access. December and January see highs around 10°C (50°F), which sounds manageable until you're standing in a slot canyon with no sun.

Moab's desert climate is trending drier and hotter, like much of the American Southwest. 2026 will likely follow the pattern of recent years: earlier springs, later autumns, and more intense summer peaks. If you're flexible, treat October as your primary window—it has spring's comfort without spring's unpredictability. March is the contrarian's choice: fewer crowds, lower prices, and you'll have the trails mostly to yourself if you don't mind layering up.
