One page for Kathmandu climate: monthly averages, sourced from public APIs and refreshed automatically. Expect 11.1 C at the coldest (Jan) and 24.8 C at the warmest (Jun) — a 13.7 C spread. Expect a wet season rather than rain year-round: Jul brings 9.04 mm/day against 0.11 mm/day in Nov. Taken together that is roughly 1,077 mm of rain a year for the grid cell. Every run re-reads the source and only rewrites this page when a figure actually changed. Exact monthly values are in the table; links below cover adjacent locations and years.

What the Kathmandu climate table shows
Values are multi-decadal climatological averages for the 27.7017, 85.3206 grid cell, not a single year. Rain is the daily mean, so a value of 2.00 mm/day is about 60 mm across a 30-day month. Averages smooth over extremes, so use them for planning rather than for what to pack for next Tuesday.
Frequently asked questions
Does Kathmandu get the same every year?
Close to it. Averaging decades smooths variation, so treat these as typical rather than guaranteed.
