Pokhara in May

October through April gives you clear skies and visible mountains — crucial when the peaks are the main attraction. October and November are peak season, meaning crowds and higher prices, but also perfect weather for trekking. December through February brings crisp mornings and warm afternoons. You'll need layers for early morning mountain views, but by noon you're back in t-shirts. This is shoulder season, so better deals on accommodation. March and April warm up nicely, with rhododendrons blooming in the hills. The air gets hazier as summer approaches, but mountains stay visible most days. Avoid May through September unless you love monsoon rain and cloud-covered peaks. The mountains disappear behind clouds for weeks at a time, and trekking becomes muddy misery.
