Climate and UV Patterns
West Palm Beach's tropical climate delivers extreme summer UV of 10-11 and keeps winter midday values around 5-6 — the kind of 'off-season' sun that outburns a northern June. The dry season (November through April) is also the sunny season, so the months when snowbirds and tourists arrive combine maximum sunshine frequency with UV that their skin isn't conditioned for.
UV Index and Health Impact
Understanding UV radiation levels is crucial for protecting your health. Typical clear-day UV index values in West Palm Beach through the year:
- Summer: Very High to Extreme (9-11)
- Spring/Fall: High to Very High (7-9)
- Winter: Moderate to High (5-6)
- Peak UV hours: 10 AM - 4 PM
- Cloud cover can reduce UV by 20-40%, but does not eliminate it
- Clear skies bring maximum UV exposure
Local Weather Patterns
Wet-season days run hot and bright until afternoon storms build off the Everglades and sweep east, usually after the peak UV window has passed. Winter delivers week after week of dry, breezy, cloud-free weather — flawless golf and boating conditions under a midday sun that quietly maintains burn-capable UV. The lagoon and nearby Atlantic add water reflection to waterfront hours in every season.
