What this does not tell you
The station is 2 km from the map pin, and we have no data for the islands in the bay. The table has no sea temperature, wave or visibility data, and it does not say how much a single week can differ from the month's average. The regulation does not state the observation period of its tables. The nearest airport with scheduled service is Cam Ranh (CXR), 27 km from the pin in a straight line, listed with every other airport in our airports guide. The Nha Trang page has the same climate table next to the airport and photo details.
