Same data, same method, different place.

Your own numbers, worked out on the page.

Across the 2001-2020 normals, the warmest month in Tarakan is May at 28.3 degrees and the coldest is January at 27.1, a swing of 1.2 degrees over the year. Those are monthly averages for the model cell the city sits in, not readings from a weather station in it.

Rain is heaviest in December, about 295 mm, and lightest in February at roughly 182 mm. Over a full year the cell above Tarakan collects around 2,897 mm.

No month in Tarakan averages between 15 and 24 degrees, so the year does not pass through what this page calls mild at all.

Humidity peaks in January at 82 percent, and the windiest month is February at 2.5 metres per second. Both are monthly means from the same twenty year series as the temperatures.

Rainfall is not spread evenly: 52 per cent of the year total falls in December, January, February, March, April and May.

2 months average 28 degrees or more: April and May.

Every figure here comes from one NASA POWER grid cell, at 3.31, 117.59, covering Tarakan on the 2001-2020 climatology. One cell, one period and one provider for every month, which is what makes the twelve rows comparable with each other.

The source publishes a monthly mean and, separately, the highest and lowest values it recorded in twenty years. Those extremes are not a typical afternoon or a typical night, so nothing here is quoted as one. This page does not say what the daytime high usually is, because this source cannot say it.

Normals are not a forecast. They describe what twenty years averaged to, and any single year can sit well outside them. They also describe a model grid cell of roughly fifty kilometres rather than a weather station, so a coastal city and the sea beside it share one figure.
