For Batam, Indonesia, the climate data cover 2013–2023.

Climate overview
Temperature
January has the lowest monthly mean temperature, at 26.2 °C, while the highest monthly mean is 27.6 °C in May. These monthly averages give a sense of the year’s temperature range, but they are not daytime maximums and cannot show how temperatures vary from day to day. Across the calendar months, the unweighted mean of monthly means is 27.0 °C.
Rain
Mean daily rainfall is lowest in February, at 4.16 mm/day, and reaches its highest monthly mean in November, at 10.40 mm/day. These are daily averages, not monthly rainfall totals; neither figure establishes how often rain falls or guarantees that a particular day will be dry or wet. The unweighted mean across the monthly daily-rainfall averages is 6.84 mm/day.
Sunshine
Mean daily sunshine duration peaks at 10.51 hours/day in March and is lowest at 8.04 hours/day in November. The unweighted mean of monthly sunshine averages is 9.41 hours/day per day. These figures can help with broad outdoor-planning expectations, but average sunshine duration is not the same as day length and does not promise clear skies on a particular date.
Best Travel Time Guide for Batam, Indonesia: Ideal Seasons and Weather Insights
For visitors prioritising lower average rainfall, February is the conditional option to consider, with mean daily rainfall of 4.16 mm/day; it is not a guarantee of dry days or a measure of rain frequency.

Those who prefer cooler monthly averages can use January as a reference, when the mean temperature is 26.2 °C.

For outdoor plans where average sunshine duration matters, March has the highest monthly mean at 10.51 hours/day per day, while November has the lowest at 8.04 hours/day per day.
