April in Rock Islands — off-season conditions

Days in April average 27°C (81°F) and humidity near 85% — 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 380 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 3.1/10 on the same scale — 5th of 12 months, versus 3.2/10 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.

Budget for mid-season pricing, and crowds are moderate.
