August in Phuket — workable with trade-offs
Days in August average 28°C (83°F) and humidity near 84% — front-load outdoor plans before the heat builds and treat the middle of the day as indoor time.
This is the year's wettest stretch at 324 mm, but with about 20 days with 6+ hours of sunshine it is not a total loss; an indoor fallback covers the risk.
That is 6.2/10 on the same scale — 7th of 12 months, versus 8.4/10 for the best month here.
Pack the lightest breathable clothing you own, a hat, and more water than feels necessary, a proper rain shell rather than an umbrella.
Expect mid-season pricing, and crowds are moderate.
If your dates are flexible, January is materially better in Phuket — 2.2 points higher on the same scale.
