Palm Springs in September

October through April delivers that perfect 75-85°F weather everyone talks about. January and February see the most crowds and highest prices - expect resort rates to double during peak season. March brings spring training baseball and festival season, including the Palm Springs International Film Festival. But here's what locals know: May and September offer sweet spots with fewer crowds and reasonable temperatures. Summer means serious heat - we're talking 110-120°F daily from June through August. Some restaurants and attractions close or reduce hours. Pool season runs year-round, but you'll appreciate that air conditioning. Winter nights can dip into the 40s, so pack layers. Rain stays rare, but when it comes, it can flood washes and low-lying roads.
