Which months suit which plans
A planning guide, not a promise.
February to April
The driest part of the year, with highs from 27.6 to 31.8 °C (82 to 89 °F) and rainfall under 50 mm a month. A good window for the coast, the cape and the basalt rocks. The sea can still be rough.
Ganh Da Dia →May to August
The hottest months, with highs of 33.9 to 34.5 °C (93 to 94 °F). Rainfall stays low, between 45.5 and 90.8 mm a month. Plan outdoor stops for early morning or late afternoon.
Mui Dien →September
The turn to the wet season. Average rainfall jumps to 227.4 mm (9.0 in), and the storm season is still on.
October and November
The wettest months, with more than 500 mm in each. The UK government lists floods in central Vietnam as most likely in October and November, and road links can be cut. Keep your plans flexible or choose another season.
Beach notes →December and January
Rain eases but remains noticeable: 216.5 mm in December and 66.9 mm in January. Highs fall to 26.4 to 26.6 °C (80 °F).
Storms, floods and what happened in 2025
Seasonal rules and one dated example.
The UK government updated its tropical storm note for Vietnam on 21 September 2026 and gives the storm season as May to November. Tropical storms can cause serious travel disruption, which includes cancelled flights and closed roads. Central Vietnam lists its rainy season as October to December.
Two dated examples show what that means. On 6 November 2025, ahead of Typhoon Kalmaegi, the aviation authority announced a temporary closure of Tuy Hoa Airport from 15:00 to 20:00 local time. On 20 November 2025 floods covered access roads and cut power at the airport, and operations were paused from 10:00 on 20 November to 12:00 on 21 November. A report from February 2026 describes severe floods in the second half of November 2025 and rebuilding in early 2026. These are past events, not today's status.
Before a trip in the wet season, check the forecast, your airline and the road situation. Read the notes on getting there as well.
