Sikkim, India
May is the last reliable trekking window. Days are warm, visibility remains good in the mornings, but afternoon clouds build with increasing frequency.
The May story
If you missed the March-April window, early May still works. By late May, pre-monsoon moisture pushes in and cloud cover becomes persistent.
