Adams Peak in May

I should know the answer to this but for some reason I am drawing a blank.
When is the " season " finished there ?
I mean, when do the monks pack up their bowls, little radios and rain gear and head down switching off the lights as they go ?
I am planning an accent in May and enjoy the chit chat at the tea stalls and the trip up and back would not be the same without it.

Please let me know from first hand experience.

Last weekend is Wesak, which is May 8th and 9th this year.
