Hi Craig,

The weather in Da Nang in Dec is not suitable for swimming. Somethimes there are storms but it's not predictable.

Hi Craig, the weather in Da Nang in December is cold for local people but for foreigners- it's cool and little warm. It's about 18-22 degree, some my friends they still could swim on resort pool, but for the beach, they did not. Cause the weather is little raining in that weather. 

Hi Craig, the weather from December to February is the most cold months of the year in Da Nang, about 18-22 oC. And there's pretty much rain during this period so it might not pecfectly suitable for swimming.
