Compare all twelve months at a sampled 6.42 m island point

Sibu Island monthly climate across tropical reef, vegetation, and rainforest settings

Sibu Island’s sampled mean temperature is 26.56 °C in January and 28.60 °C in May. Daily precipitation averages 3.99 mm in February and 11.63 mm in December, while wind speed measures 2.79 m/s in April and 5.97 m/s in January. NASA POWER’s 1991–2020 record represents one 6.42 m island coordinate, while squalls, sea exposure, and weather across the wider protected waters may differ.
