Weather in Kota Bharu in January

Shoulder season. January sits in between. You will get good days and you will lose some. You should expect rain on 17 days of the month, which is more days wet than dry.

January ranks 3 of 12 in Kota Bharu. Only February scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 17 days, 5 of them heavy. Enough to need a plan B, not enough to need a plan around it. Natural fibres and a second shirt for the day. At 85% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average January reaches 30 °C; the day barely swings — 3.1 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest January day reached 30.3 °C and the coldest night fell to 22.1 °C, and the wettest single day dropped 153 mm — roughly 79% of the month's rain in one day.

January is moderately variable: 34 mm in the driest year against 689 mm in the wettest, around an average of 193 mm. Roughly two Januarys in three land near that average, and the third does something else entirely.

Wind is light at 10.5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity at 85% is the real story though — it is the number that decides how the day feels, not the 27.6 °C.

How January sits in the year

Temperatures hold steady either side: 27.9 °C in December, 27.6 here, 28.2 in February. Nothing about the timing within the month matters much. Rain is the thing that moves: February brings 8 days less of it, so pushing the dates later buys drier weather.

Daylight in January

Kota Bharu sits close enough to the equator that daylight barely moves all year — 11.8 hours in January, against a range of just 0.7 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

Sea temperature

The sea sits at about 27.7 °C in January — warm enough that the water offers no relief from the heat. The sea peaks at 30.5 °C in May and bottoms out at 27.7 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

How busy it gets

Quiet. Few other visitors, cheaper rooms, and a real chance some seasonal operators are shut.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

January in Kota Bharu versus nearby

If Kota Bharu is one option among several, the nearby comparison is worth making. Ipoh is the weaker option in January — 2.7 °C warmer, 3 days more rain. Kota Kuala Muda is close enough to be a coin toss — 2.8 °C warmer, 1 day less rain.

So: January works, with February the better month by 17 points if the dates can move. If they cannot, nothing here should stop you booking.
