Swipe the table sideways to see every column.
The nearest station is on the coast at Dong Hoi. The national park is inland, so conditions there can differ.
These are our own thresholds, not part of the source data. A month is Drier when it has under 100 mm of rain, no more than 12 rainy days and fewer than 10 foggy days. Otherwise it is Wet (over 250 mm), Foggy (10 or more foggy days), Showery (15 or more rainy days) or Mixed. A month close to a threshold is close to the next label, so read the numbers.
The source does not define a “rain day”. Crowds, prices and storms are not part of this table.
Observation period: not stated by the source. The regulation does not state the observation period of these tables.
