The short answer
The mountain flight needs clear air, and clarity is highest in the dry months. October to November is the favourite, with December to February also very clear but colder on the ground. March to May is good in the early morning before haze builds. In monsoon, cloud often hides the peaks and flights may be rescheduled.
Morning is nearly always the better time because cloud builds later. If a flight is cancelled for weather, operators usually offer another slot, so leave a spare day if you can.

Why mornings matter
Haze and cloud build later in the day, so most mountain flights depart at first light. Clear mornings after a night of rain can be spectacular. If your flight is cancelled, ask about rebooking for the next day rather than refunds only.
Book a flexible window if you can, since one cancelled day is common in poor-weather months.
Managing expectations
Even in the best months, individual days vary. Treat the flight as a chance and plan other things for the rest of the day. If you are not happy with a cloudy flight, ask the operator what their policy is before booking.

Avoid this
