Weather extremes
How extreme does Kathmandu's weather get?
The hottest, coldest, wettest and snowiest days Kathmandu has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.
The four kinds of extreme
The hottest, coldest, wettest and snowiest single days Kathmandu has recorded — each shown against what a normal day that time of year looks like.
That is about 14°F hotter than a normal May afternoon in Kathmandu (typical high near 84°F).
The three most extreme on record
About 10°F colder than a normal January night in Kathmandu (typical low near 36°F).
The three most extreme on record
About 89% of a typical September's rain in a single day (Kathmandu averages roughly 8.6 in across the month).

How hot and cold it gets, month by month
The shaded band is the normal range of daily temperatures for each month. The dots show the most extreme it has ever been — so you can see how far beyond a normal day the records really sit.
Kathmandu's record heat sits well above even a hot day for the season — May's 98°F is about 14°F beyond a normal hot afternoon. Its record cold is just as far below a normal winter night — the dots mark how rare each extreme really is.
