會安市逐月天氣

Hoi An-forum threads on January beach weather are candid that the whole mid-October-to-early-January stretch is best avoided for poor conditions, sometimes typhoons, and January itself still sits inside that damp tail end - overcast more often than clear, the sea rough, light showers a regular feature rather than an exception, genuinely not beach weather. The flooding threads that dominate the forum are mostly about November events, and posters there note floods typically vanish within about a week, leaving little trace once they've passed. By January proper, regulars call conditions fine for a town visit even if the beach isn't the draw. The record: 25.2C days feeling like 27C, 20C nights, 181mm across a notably high 20 days, 86 percent humidity, a 23.1C sea and just 6.8 hours of sun - one of the cloudiest, dampest entries on this destination's whole calendar.

February in Hoi An is the month people mis-pack for. Regulars put it at roughly 15 to 25C with light drizzle most days, overcast stretches and showers overnight or in the morning that dry up quickly - our row says 26.1C days and 20.3C nights with 103.3mm across 13.9 precipitation days at 86 percent humidity. Their summary is that it is cool and pleasant for cycling and walking the old town, and that it is jeans-and-jumpers rather than bikinis, with a jacket worth carrying. Warmer years happen - one recent February ran 27 to 30C by day - but the drizzle is the constant. There is less rain than the autumn, which is the main thing February has going for it. The record: feels-like 29C, 7.9 hours of sun and a 23.4C sea.

Hoi An-forum threads on March weather call it sunny and warm without the punishing heat that arrives later - low humidity for the region, a nice breeze most days, and temperatures regulars describe as comfortable for walking the old town all afternoon. February through April is singled out as the driest, mildest stretch of the year, and posters consistently rank March and April among the best months to visit specifically because the tourist season is quieter than the winter peak. Beach conditions by the end of March get a specific mention as genuinely pleasant, warm enough for swimming without summer's more oppressive humidity. The record shows a touch more rain and cloud than the sunniest framing implies, but nothing that regulars consider a problem for a week-long visit. The record: 28.8C days feeling like 33C, 22.5C nights, 82mm across 9.4 days, 86 percent humidity, a 24.2C sea and 9.8 hours of sun.

March is dry, warm and pre-crowd. Avoid October and November here whatever the score says — the Thu Bon floods the old town most years and shops board up. The beach at An Bang is best before 10am.

Hoi An-forum threads on April weather call it usually beach weather unless a visitor gets genuinely unlucky, still comfortably inside the dry, mild stretch that runs February through April before the real heat of May and June sets in. One thread notes sun didn't fully return until after the 20th in a particular year, the earlier part of the month running greyer and more overcast than the reputation suggests, so April isn't a lock for wall-to-wall sun. The sea has calmed by this point, the rougher swell of the northeast monsoon having faded away by late March. Rain when it shows up is typically a short afternoon burst rather than a washout. Posters call late April specifically a strong bet for the best combination of sunshine and manageable heat before summer's harsher temperatures arrive. The record: 31.6C days feeling like a punishing 38C, 24.4C nights, 79mm across 7.7 days, 83 percent humidity, an unhealthy 93 AQI and a 26C sea.

Hoi An-forum threads on May weather call it hot rather than wet - blue skies most days, low chance of rain, with any showers arriving as a short afternoon burst rather than settling in. Posters flag the old town's open-air shopfronts specifically: an Australian visitor used to heat still found the mid-30s genuinely hard to escape indoors, since the historic buildings have no glass windows to seal in air conditioning. The standard advice is to front-load sightseeing for early morning or dusk and treat midday as beach or pool time at nearby An Bang. Regulars call May a good-not-great month overall, solidly ahead of the wetter months later in the year but past the cooler, more comfortable spring window. The record: 34C days feeling like a sticky 40C, 26C nights, 109mm across 16.1 days, 80 percent humidity, an 88 AQI and a 28.2C sea - hot and humid exactly as the forum describes, with more rain days than the "blue skies" framing implies.

Hoi An-forum threads on July weather are clear that this isn't the region's rainy season - that arrives later, October through January, when the real flooding and typhoon risk lives. July itself is simply hot: light winds, clear air, and days regulars describe as balmy even after dark. Posters note it does still rain a fair amount by volume, but almost always as a short, sharp afternoon burst of thirty to sixty minutes that rarely derails a day's plans. The Cham Islands boat trip stays reliably on the table this month, An Bang Beach is warm enough to swim for hours, and hotel rates run well below the December-February high season. The standing advice is simply to plan around the hottest hours - late morning through mid-afternoon - the way locals do. The record: 34.9C days feeling like a punishing 42C, 26.6C nights, 127mm across 18.2 days, 74 percent humidity, a 99 AQI and a 29.8C sea - hot exactly as billed, with a heavier rain tally than the "not the wet season" framing suggests.

Forum posters describe September as the start of Central Vietnam's rainy season, with hard downpours becoming more likely from around mid-month, though posters are consistent that early September stays comparatively better with mostly sunny mornings and a real but manageable chance of afternoon showers. Posters cite average highs around 88F (31C) with roughly 19 days a month seeing some rain, describing a typical day as short, sharp showers rather than sustained rain. Posters consistently recommend visiting earlier in September rather than later, since the risk of torrential rain and typhoon activity increases noticeably as the month progresses toward October. Posters flag real crowd relief as a genuine upside of this off-season stretch, with both An Bang beach and the Old Town noticeably quieter than peak months.

Travel-forum threads are unusually consistent about Hoi An's weather: destination experts describe Hoi An and Hue as breaking from the usual Southeast Asian pattern, with a rainy season running October to December rather than July to October like most of the region. Visitors are warned plainly that November is a bad time for Hoi An and that flooding is a real risk, with February to mid-April the recommended window and April often called the best month of all. November's record backs the warning: 28.1C days, 23.1C nights, 23 precipitation days and close to 500mm across the month, with the sea at 27.7C - warm, but this is the wettest stretch of the year.
