Which Month to Visit Hoi An? Month-by-Month Weather for the Old Town, Beaches and Islands

February through April is the most comfortable window for walking Hoi An Ancient Town: rainfall is at its lowest, daytime sun is mild, and evenings feel pleasant. If your priority is swimming at An Bang or Cua Dai Beach or taking a speedboat out to the Cham Islands, aim for March through August when the sea is calmest—keeping in mind that midday hours from June to August are hot. October and November bring the heaviest rain of the year, when riverside streets along the Hoai River can flood and Cham Islands speedboats are frequently suspended.

Because seasonal transitions shift by a few weeks from year to year, treat the monthly notes below as practical planning ranges rather than fixed calendar cutoffs.

Quick Choice by What You Plan to Do

• Walking the Ancient Town and daytime photography: February to April. Temperatures are mild to warm and long-term average rainfall is among the lowest of the year.
• Beach time and Cham Islands speedboats: March to August. From September onward, rougher swells often pause speedboat departures from Cua Dai Port; if travelling then, keep a flexible backup day. For island fee details ( Vietnamese dong per person under Resolution 16/2026/NQ-HDND), read Cham Islands speedboat ticket and private car pricing.
• Cool weather before heavy rain: February and March. December and January are also cool, but still see periodic rain showers.
• Avoiding low-lying street flooding: travel outside late September to early December. Flood risk peaks between mid-October and late November; if your dates fall in that window, read our guide on Central Vietnam storm season and schedule management.
• Fewer crowds: avoid Lunar New Year (Tet), the April 30 – May 1 holiday, and peak domestic summer weeks in June and July. March and early April sit between major holidays with dry weather.
• Full-moon lantern nights: the 14th night of the lunar month happens every month of the year, so pick your season for weather first and then align with the lunar calendar.

Hoi An Weather Month by Month

The table below reflects multi-year climate patterns for the Da Nang – Hoi An coastal zone, with approximate daytime highs and nighttime lows:

Month	Typical conditions	Practical planning notes
January	Cool, among the freshest months of the year: daytime ~25°C, night ~19°C; light monsoon showers possible.	Pack a light jacket for evening walks. Tet occasionally falls in late January.
February	Mild and one of the driest months of the year.	Ideal for walking the old quarter and cycling to craft villages. Book cars early if Tet falls in February.
March	Warming gently with low rainfall.	Great balance for both the Ancient Town and An Bang Beach; sea crossings to the Cham Islands become steadier.
April	Brighter sunshine and still relatively dry.	The late-April national holiday draws heavy domestic travel—reserve transfers early.
May	Hotter days with occasional brief afternoon showers.	Schedule old-town walks for early morning and late afternoon; sea conditions remain calm.
June	Hot and sunny: average daytime highs around 34°C.	Rest indoors or in air-conditioned comfort at midday; peak domestic family holiday season.
July	Alongside June and August, the hottest stretch of the year with scattered showers.	Good sea conditions for the Cham Islands and An Bang Beach; bring sun hats and water.
August	Still hot, with showers gradually increasing toward late month.	Late-summer beach window; keep an indoor backup activity for afternoon rain.
September	Seasonal transition: rainfall rises and tropical depressions can form.	Speedboats to the Cham Islands begin facing weather holds; check port notices daily.
October	One of the two wettest months; storms and monsoon rain can affect Central Vietnam.	Riverside lanes in the Ancient Town may flood during heavy rain; car pickups move to high-ground perimeter lots.
November	Prolonged rain and cooler air.	Allow extra buffer time before flights and train departures in case pickup points shift.
December	Rain eases gradually though overcast days remain; cooler evenings.	Early December can still see high water; late December picks up for Christmas and New Year travel.

Three Monthly Factors That Change How You Schedule a Car

• Midday heat (roughly May to August): split your day into two blocks—walk the Ancient Town or cycle early in the morning and after 16:00, leaving midday for lunch and indoor rest.
• High water on low-lying streets (roughly October to early December): when streets next to the Hoai River flood, private cars meet passengers at higher perimeter lots outside the old quarter. Add extra buffer time when heading to Da Nang Airport or Da Nang Railway Station.
• Cham Islands boat suspensions (roughly September to February): port clearance is decided each morning by maritime authorities. If you booked a private car to Cua Dai Port and boats are cancelled, notify dispatch early to adjust your pickup time or switch to an overland route.

Which months are best for swimming at An Bang Beach and visiting the Cham Islands? +

March through August offers the calmest sea conditions and the most reliable speedboat departures to the Cham Islands, with June through August being the hottest months. Always swim in lifeguarded zones and obey beach warning flags.

Which months should we avoid if we are concerned about street flooding in Hoi An? +

Mid-October through late November sees the highest rainfall and the most frequent waterlogging along streets bordering the Hoai River. Heavy rain can occasionally extend into early December, so check local forecasts close to your trip.

Is Hoi An very crowded during the Lunar New Year (Tet) holiday? +

Weather during Tet (late January or February) is pleasantly cool, but visitor footfall is high and hailing on-demand rides at peak evening hours takes longer. Booking a private car in advance and setting a clear perimeter pickup point keeps transfers smooth.

How should we adjust our day if heavy rain hits during our stay? +

For light rain, focus on neighbouring indoor museums, assembly halls, or craft workshops. If heavy rain or flood warnings occur, postpone island boats and cycling, and message your car dispatch early to move your pickup point to higher ground.
