Local context
What to expect in September
Autumn in Phuket is often underrated: 29°F, golden light and declining crowds. An interesting window. With 82% of rainy days, always have indoor alternatives planned. Not the best window, but acceptable if dates are constrained. January (7.8/10) is significantly better if possible.
