Weather in Medan in March

A hard month. March asks something of you. Go in knowing what. You should expect rain on 21 days of the month, which is more days wet than dry.

Medan barely has seasons. March scores 46 out of 100 against a best of 54 in February — a gap small enough that the month you choose matters far less here than the week you choose.

Rain on 21 of the month's 31 days, 4 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 85% nothing dries, including you.

What the averages hide

Averages flatten a month, and this one hides a few things: 20 days top 30 °C, making the heat continuous rather than occasional; the day barely swings — 6 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest March day reached 32.6 °C and the coldest night fell to 21 °C, and the wettest single day dropped 69 mm — roughly 49% of the month's rain in one day.

March is moderately variable: 51 mm in the driest year against 369 mm in the wettest, around an average of 142 mm. Roughly two Marchs in three land near that average, and the third does something else entirely.

Wind is light at 4.4 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 30.2 °C.

How March sits in the year

Temperatures hold steady either side: 29.7 °C in February, 30.2 here, 30.5 in April. Nothing about the timing within the month matters much. Rain has already shifted: 5 days more than February had.

Daylight in March

Medan sits close enough to the equator that daylight barely moves all year — 12.1 hours in March, against a range of just 0.4 hours across the whole calendar. Sunrise and sunset land at roughly the same time whenever you come.

Sea temperature

The sea sits at about 29.7 °C in March — warm enough that the water offers no relief from the heat. The sea peaks at 30.4 °C in May and bottoms out at 28.8 °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

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.

March in Medan versus nearby

If Medan is one option among several, the nearby comparison is worth making. Ipoh is close enough to be a coin toss — within a degree on temperature, the same number of rain days. Kota Kuala Muda is close enough to be a coin toss — within a degree on temperature, 3 days less rain.

So: March works, with February the better month by 8 points if the dates can move. If they cannot, nothing here should stop you booking.
