Weather in Pekanbaru in April

Indonesia · 20-year averages, April

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

Pekanbaru barely has seasons. April scores 43 out of 100 against a best of 47 in January — 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 30 days, 10 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 91% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: 11 days top 30 °C — hot spells arrive, but they break; the day barely swings — 5.3 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest April day reached 32 °C and the coldest night fell to 22 °C, and the wettest single day dropped 95 mm — roughly 33% of the month's rain in one day.

April is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest April on record still delivered 384 mm against 138 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 288 mm average is a reasonable planning figure, not a promise.

Wind is light at 0.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity at 91% is the real story though — it is the number that decides how the day feels, not the 29.6 °C.

How April sits in the year

Temperatures hold steady either side: 29.7 °C in March, 29.6 here, 29.6 in May. Nothing about the timing within the month matters much.

Daylight in April

Pekanbaru sits close enough to the equator that daylight barely moves all year — 12.1 hours in April, against a range of just 0.1 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: 6.4 °C between the year's warmest afternoons and coldest nights.

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 Pekanbaru versus nearby

If Pekanbaru is one option among several, the nearby comparison is worth making. Padang is close enough to be a coin toss — within a degree on temperature, the same number of rain days. Singapore is close enough to be a coin toss — within a degree on temperature, 1 day less rain.

So: April is effectively as good as it gets here — 4 points behind January, which is inside the margin where the weather stops being the deciding factor and price starts being it.
