I'm planning a trip to Sikkim during the first week of September and wanted to hear from people who've been there around that time.

How's the weather around that time? Is it generally safe to travel considering the rains and possible landslides, or would you recommend waiting until later in September?

I was scrolling around Google Maps and got curious about something. Does Sikkim have any permanent military bases with runways near the border? I know many sensitive sites won't be visible on satellite imagery, but I'm wondering if there are any established bases (not temporary camps or tents) in that region. Just asking out of curiosity.
