March in Ha'apai — the hardest end of the year

Days in March average 27°C (80°F) and humidity near 80% — 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 308 mm, but with about 24 days with 6+ hours of sunshine it is not a total loss; an indoor fallback covers the risk.

That is 4.2/10 on the same scale — 11th of 12 months, versus 8.1/10 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.

Expect low-season pricing, and crowds are light for this destination.
