Weather in Kathmandu in March

Prime time. March is about as good as Kathmandu gets. Highs average 24.8 °C, lows 12.4 °C, and rain falls on 4 days — nothing in the month is working against you.

March ranks 3 of 12 in Kathmandu. Only November scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain falls on only 4 days, so an itinerary with no wet-weather fallback is a reasonable risk. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest March day reached 31.6 °C and the coldest night fell to 3.5 °C.

March is moderately variable: 0 mm in the driest year against 65 mm in the wettest, around an average of 21 mm. Roughly two Marchs in three land near that average, and the third does something else entirely.

Wind is light at 6.4 km/h, so the temperature on the page is close to the temperature on your skin, and the air is dry at 37% humidity, which makes the heat far more bearable than the same figure somewhere humid — and dehydrates you faster than you expect.

How March sits in the year

The month is on the way up: 4.4 °C warmer than February, and April adds another 4 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in March

12 hours of daylight, gaining 0.8 hours across the month. That is between Kathmandu's extremes of 13.9 and 10.4 hours, so days are long enough not to constrain the plan.

An inland climate

Despite being inland, the year stays fairly even: 23.1 °C between the year's warmest afternoons and coldest nights. At 1317 m the air is thin enough to matter — sun that burns faster than the temperature suggests, and nights that cool off quickly.

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.

March in Kathmandu versus nearby

If Kathmandu is one option among several, the nearby comparison is worth making. Bharatpur is the weaker option in March — 8.5 °C warmer, the same number of rain days. Pokhara is close enough to be a coin toss — within a degree on temperature, 1 day more rain.

So: March is effectively as good as it gets here — 6 points behind November, which is inside the margin where the weather stops being the deciding factor and price starts being it.
