Monthly Weather Highlights

January – February

Winter months bring the lightest temperatures and occasional winter rain. The mornings can feel crisp, but daytime clouds are rare. Ideal for winter golf and low‑humidity workouts.

March – May

Spring sees steadily higher temperatures and the first hints of monsoon activity by late May. This is a prime time for hiking—temperatures are still mild before the heat wave kicks in.

June – August

Summer is the most intense period: high heat, minimal rainfall early in the season, and the monsoon season from June to September. Flash floods are a rare but real risk in the later summer; staying hydrated is critical.

September – October

Cooler days begin to replace the blistering heat. The monsoon season wanes, creating perfect outdoor conditions for golf, desert tours, and sunset photography.

November – December

Winter arrives with cooler temperatures and occasional snow on the higher desert canyons. Daylight hours are longer, and the humidity stays comfortably low.
