Weather in Kota Bharu in April

Shoulder season. April 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.

April ranks 5 of 12 in Kota Bharu: past the worst of the year but short of February, which is the month to book if the dates are open.

This is persistent light rain rather than storms: 17 wet days but only 2 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. Pack for 30.5 °C days and 26.5 °C nights; the spread matters more here than any single number.

What the averages hide

Averages flatten a month, and this one hides a few things: 19 days top 30 °C — hot spells arrive, but they break; the day barely swings — 4.1 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest April day reached 34.3 °C and the coldest night fell to 24.6 °C, and the wettest single day dropped 57 mm — roughly 59% of the month's rain in one day.

April is moderately variable: 9 mm in the driest year against 246 mm in the wettest, around an average of 97 mm. Roughly two Aprils in three land near that average, and the third does something else entirely.

Wind is light at 7.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 81%, high enough to notice on the warm days without dominating them.

How April sits in the year

Temperatures hold steady either side: 29.3 °C in March, 30.5 here, 31 in May. Nothing about the timing within the month matters much. Rain is the thing that moves: May brings 9 days more of it, so the earlier half of a flexible trip is the safer half.

Daylight in April

Kota Bharu sits close enough to the equator that daylight barely moves all year — 12.3 hours in April, 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 29.9 °C in April — warm enough that the water offers no relief from the heat. This is the warmest the water gets all year.

How busy it gets

Off season. The genuine off season: cheapest by a distance, with the caveat that some tours and restaurants close entirely.

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

April 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 April — within a degree on temperature, 6 days more rain. Kota Kuala Muda is the weaker option in April — within a degree on temperature, 7 days more rain.

So: April is a compromise. February is 23 points better and is what Kota Bharu is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
