| Station | Cam Ranh station, via the weather box in the English Wikipedia 'Cam Ranh' article, sourced there to the Vietnam Institute for Building Science and Technology (with nchmf.gov.vn for the July record high). No record period (year range) is stated. |

| Sea Temp Station | Sea temperatures are NOT from the Cam Ranh station (its climate box has no sea data). They are Nha Trang figures (about 50 km north) from climatestotravel.com. |
| Koppen | Aw (tropical savanna) |
| Note | The English Wikipedia 'Nha Trang' article no longer carries a climate box - it was rewritten as an administrative-ward stub during the 2025 provincial reform. climate-data. org and seatemperature. |
| Dry Season Months | January to August at the Cam Ranh station (every month under 90 mm). climatestotravel describes the Nha Trang dry season more narrowly as January to April. Alma Resort states January to August dry. |
| Rainy Season Months | September to December, peaking October and November (October 248.8 mm, November 319.6 mm) |
| Typhoon Risk Months | Main risk early September to 10 December; a weaker secondary window late April to late June. Direct hits are rare because of the sheltering mountains and islands, but storm fringes bring wind and rain in late October and November. |
| Best Months To Visit | Mid-January to March is the sweet spot - dry, sunny and the coolest part of the dry season. January to April is best overall; May to August is peak for water sports (hot, calm, clear); September to December is the quietest and cheapest but wettest. |
| Kitesurf Wind Season | November to March is the dependable wind season at Bai Dai / the Cam Ranh coastline; April to September is the calm, flat period. No wind-speed climatology figures were found on any fetched page. Surf-forecast lists Bai Dai's best surf as ENE swell with WSW offshore wind, October being the prime month, though clean waves occur only about 16% of the time and it is blown out about 67% of the time. |
| Jellyfish Notes | Peak jellyfish season is April to August. Fire jellyfish cause most tourist stings around Nha Trang; box jellyfish are present in central Vietnamese waters May to August but are rarer. The Nha Trang Bay Management Board posts beach staff during the summer months. |
| Rough Sea Notes | The rough-sea season runs roughly from the 9th lunar month to Lunar New Year, bringing big waves and strong winds. The September to December rainy season brings strong waves and occasional flooding. A red flag means a strong undercurrent and swimming is prohibited. Summer (May to August) is calm, with snorkelling visibility often over 20 m. |
