Aviation weather in South Asia

The southwest monsoon dominates half the year, with heavy rain, low ceilings and reduced visibility, while winter brings the dense radiation fog that regularly closes northern Indian airports at dawn.

What these hazards mean

Monsoon rain Months of heavy rain with low ceilings, standing water on the runway and embedded convection inside an otherwise featureless layer.
Low visibility Fog, mist, haze, dust or heavy precipitation cutting visibility below the minimum for the approach in use.
Thunderstorms Cumulonimbus cells carrying severe turbulence, hail, lightning and downdraughts; avoided laterally, never flown through.
Tropical cyclones Typhoons, hurricanes and cyclones close airports for days and reshape the route network for a week either side.
High temperature Density altitude cuts engine and wing performance; above certain temperatures some aircraft simply cannot depart at weight.

Written in house

Every guide is researched and written by our editorial team from the published documentation, not rewritten from another site.

Reviewed on a schedule

Each guide carries the date of its last review, and we publish the date even when nothing changed.

Sources named

Where a threshold comes from ICAO Annex 3, an FAA category or a national service, the guide says which.

Twelve languages

Every guide is translated, not machine-popped — each language has its own URL and its own review date.

Not an operational source

We explain reports; we never issue them. The official service and the commander decide, and every page says so.
