What's the weather and sea temperature like in Nha Trang in summer (June-August)?

Early August weather is ideal: 30-33°C (86-91°F), high humidity on arrival (you adjust after a day or two). Rain is rare - only one evening shower in 10 days, pleasant to sit outside at a cafe during it.

In the local winter, residents wear jackets when it drops below 25°C. Even at night in the cool season, it rarely goes below 20°C (68°F).

Early July was changeable: sunny mornings for the first few days, then overcast but still hot from July 1st, with light rain almost daily in the afternoons. Cloud cover reduces sunburn risk, but sunscreen is still needed.

You can get sunburned at the beach even on cloudy or rainy days - sunscreen is essential regardless of cloud cover.

Sea currents occur and shift, but water temperature stays above 23°C (73°F) year-round.

Air temperature is similar morning and evening, staying stable around 28-29°C (82-84°F); evenings can feel cooler due to sea breeze from the waves.
