September in Sandakan: expect compromises
Days in September average 28°C (82°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 247 mm, but with about 23 days with 6+ hours of sunshine it is not a total loss; an indoor fallback covers the risk.
That is 4.1/10 on the same scale — 9th of 12 months, versus 5.1/10 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, footwear you can get muddy.
