The absolute best months for climbing are January, February, and September, though one could easily climb throughout the year. July/August can be colder.

The main rainy season begins at the end of March and lasts through the end of May. After that the temperatures will still be relatively warm, but massive clouds will block visibility, while dropping snow on the summit and heavy rain on the lower slopes.
The long dry season follows, and by early July and into August it can be quite cold with clear skies. It grows steadily warmer throughout September and into October, when daytimes are clear, frequently a dripping belt of mist girdles the mountain at the moorland zone (11,000 ft – 13,000 ft), leaving the summit and other peaks peaking through the clouds. Short rains return in November and last into December, when afternoon thunderstorms are common. However, by evening the clouds usually disappear, allowing for great visibility in the evenings, mornings, and nights revealing stunning views of the stars.
We recommend that you consider timing your climb with the full moon, so that you can summit under the light of the full moon.
