Business Class Flights from Washington to Mumbai

Arriving into Mumbai (BOM) from Washington (WAS), expect a tropical pattern: June–September brings very heavy rain (about 350–780 mm/month) and slightly cooler 80–83°F days; leave extra time for airport transfers and local weather delays.

Dry season from November–February is comfortable and nearly rain‑free (1–20 mm/month) with typical highs around 76–78°F; this pairs well with February’s favorable price level (98) for a smooth trip.

Heat peaks in April–May at roughly 86–87°F; plan indoor activities midday and consider evening arrivals to reduce heat fatigue after a long-haul flight.

October transitions out of the monsoon with about 100 mm of rain and 83°F; it’s a steady compromise if you want fewer crowds than December but more predictable weather than September.

If traveling in the wet months, pack quick‑dry clothing and waterproof footwear, and keep 24–48 hours of flexibility in plans in case of heavy downpours.
