อากาศดานัง เดือนธันวาคม

Regulars call this the coldest and wettest month of the year here, with rain nearly every day, though they're careful to add it doesn't rain constantly and sunny breaks do happen. Our row backs the intensity directly, a striking 435mm of rain across 24 days, alongside a real cold-for-the-tropics feel, 23.8C reading as a real 26C, over 19C nights, and just 4.5 hours of sun a day - among the lowest sunshine figures in this project. Regulars describe the Perfume River as visibly swollen this time of year, generally not dangerous for an average visitor, though flooding along riverside tourist roads has occurred in past Decembers, more often in the first half of the month than the third week onward. A proper raincoat is far more useful than a winter coat. The sea sits at 25.3C. The record: humidity 86 percent, a 15.8 kph wind and AQI 64.

Regulars are direct that this counts as genuinely hot, humid summer weather, with early morning and late afternoon named as the real windows for being outdoors and midday better spent resting or indoors. Our row backs that brutally hot, humid read, 36C reading as a scorching 44C, over 26.4C nights, with 102.5mm of rain across 15 days and humidity at 78 percent. Regulars are consistent that humidity specifically tends to peak overnight rather than during the day, a real factor for anyone choosing accommodation without reliable air conditioning. Slowing the pace, staying hydrated and expecting an afternoon shower most days are the standard local advice for this month. The sea sits at a bath-warm 31.1C. The record: 11 hours of sun, an 11.6 kph wind and AQI 102.

Da Nang-forum threads asking whether to avoid November over heavy rain get a genuinely mixed answer - this does sit at the peak of the wet season locally, and posters are direct that a typhoon tracking through the central coast is a real possibility this time of year, sometimes serious enough to disrupt a whole trip. That said, several regulars report entire November stretches with little to no rain, sunshine holding for days at a time, purely down to which specific week a visit lands on. The standing advice across threads is flexibility - build slack into any itinerary, watch the tropical outlook in the week before travel, and treat a clear day as a bonus rather than an expectation. Beach time on My Khe is a genuine gamble this month either way. The record: an extraordinarily high 495mm across over 23 days, 28.7C days feeling like a punishing 32C, 22.9C nights, a 27.8C sea and 87 percent humidity.

Da Nang-forum threads on January weather describe it as the start of the low-rain season, but posters are candid the transition isn't instant - real rainy days are still common, and one visitor reported needing long trousers, long sleeves and a jacket on several days rather than beach clothes. The sea itself is called too cold for a comfortable swim this early in the year, a genuine surprise for anyone picturing tropical Vietnam. Temperatures overall stay mild and pleasant rather than either hot or cold, comfortable for sightseeing even if the beach isn't fully in play. Posters recommend heading further south along the coast for anyone who specifically wants guaranteed warm beach weather this month, treating Da Nang itself as more of a sightseeing base in January. The record: 25.6C days feeling like 28C, 19.8C nights, a notably high 181mm across 20 days, 86 percent humidity, a 23.1C sea and 6.8 hours of sun.

May in Da Nang is hot and getting hotter - regulars give a 25 to 31C band and note it is a clear step up from April, with the reassurance that it is still not June or August. Our row runs warmer than their band at 34.1C, and once the 83 percent humidity is counted it reads as 41C, which is the figure to plan the middle of the day around. What May buys you is the water: the sea reaches about 28C, its warmest of the first half of the year, our row saying 28.7C, and My Khe and Non Nuoc are the beaches they name, the latter out towards the Marble Mountains halfway to Hoi An. The month is not dry, at 109mm across 16.1 days. The record: 25.6C nights, 10.8 hours of sun and AQI 88.
