Rain season
Kathmandu's monsoon runs June–September, delivering roughly 80% of the valley's annual rainfall. The Himalayas trap moisture from the Bay of Bengal, producing heavy afternoon downpours that clear by evening. Pre-monsoon thunderstorms in April–May are common. Winters are dry and often hazy; spring and autumn are the clearest and most pleasant seasons.
