Quick answer: the best times to trek to Everest Base Camp are October to November (clear skies and stable weather after the monsoon) and March to May (warmer temperatures, rhododendrons in bloom and the expedition season at Base Camp). Winter (December–February) is quieter but very cold, and the summer monsoon (June–September) brings cloud, rain at lower altitudes and frequent Lukla flight delays.

| Winter | December–February | Very cold, often clear; snow possible on passes | Quiet | For experienced, well-equipped trekkers |
