Weather in the Annapurna region varies sharply by altitude, valley position, season, and rain-shadow geography.
Spring and autumn are major trekking seasons. The monsoon can bring rain, clouds, leeches in lower forests, landslide risk, and reduced visibility.
Some areas beyond the main Himalayan barrier, including parts of Manang and Mustang, are drier than lower hill regions.
Weather affects trail safety, mountain visibility, transport, altitude planning, and daily clothing choices.
