Weather in Ipoh in December

A hard month. December is a hard month in Ipoh, and worth planning around. You should expect rain on 26 days of the month, which is more days wet than dry.

Ipoh barely has seasons. December scores 43 out of 100 against a best of 48 in February — a gap small enough that the month you choose matters far less here than the week you choose.

Rain on 26 of the month's 31 days, 12 of them heavy. At that frequency a wet-weather backup is not a contingency, it is the itinerary — book the indoor things first and treat the clear days as the bonus. Natural fibres and a second shirt for the day. At 89% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: 18 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest December day reached 32.6 °C and the coldest night fell to 20.2 °C, and the wettest single day dropped 75 mm — roughly 23% of the month's rain in one day.

December is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest December on record still delivered 553 mm against 192 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 320 mm average is a reasonable planning figure, not a promise.

Wind is light at 2.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity at 89% is the real story though — it is the number that decides how the day feels, not the 30 °C.

How December sits in the year

Temperatures hold steady either side: 30.3 °C in November, 30 here, 30.3 in January. Nothing about the timing within the month matters much. Rain is the thing that moves: January brings 6 days less of it, so pushing the dates later buys drier weather.

Daylight in December

Ipoh sits close enough to the equator that daylight barely moves all year — 11.9 hours in December, against a range of just 0.5 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

An inland climate

Despite being inland, the year stays fairly even: 8.2 °C between the year's warmest afternoons and coldest nights.

How busy it gets

Busy. Popular without being frantic; book the things you care about, improvise the rest.

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

December in Ipoh versus nearby

If Ipoh is one option among several, the nearby comparison is worth making. Kota Kuala Muda is close enough to be a coin toss — within a degree on temperature, 1 day less rain. Kuala Lumpur is close enough to be a coin toss — within a degree on temperature, 1 day less rain.

So: December is effectively as good as it gets here — 5 points behind February, which is inside the margin where the weather stops being the deciding factor and price starts being it.
