Hoi An climate at a glance

First, let’s understand the general climate of Hoi An.

General climate profile

• Climate type: We have a tropical monsoon climate with two very clear seasons.
• Average annual temperature: Hoi An is generally warm all year, with an average temperature of around 26°C to 28°C.
• Humidity: The humidity is quite high year-round, usually above 80%, which can make it feel warmer than the actual temperature.

How the seasons change your plans

Hoi An does not need one “best weather” label on this page. Vietnam Tourism describes September to January as the wetter, cooler and cloudier period, while February to August is generally warmer, sunnier and clearer. Use the seasonal pattern below to understand conditions; use the separate best-time guide to decide which trade-off suits your trip.Here is a simple breakdown of the seasons to help you choose:

Season	Months	Key Weather Characteristics	Traveler Benefits
Early dry season	February – April	Cool, pleasant temperatures (Avg. 20°C–28°C), minimal rain, and lower humidity.	Often comfortable for walking, cycling, photography and other outdoor sightseeing.
Hot Dry Season	May – August	Hot and very sunny (Avg. 30°C–35°C+). You can expect clear blue skies and the highest UV index of the year.	This hotter period can suit beach time, but midday heat and sun exposure become a bigger part of the plan.
Rainy Season	September – January	Cooler temperatures (Avg. 22°C–27°C), frequent and sometimes very heavy rain, and high humidity.	The benefits are fewer crowds and lower prices. It’s a great time for indoor cultural experiences, cozying up in a cafe, or getting clothes made by a tailor.

Detailed seasonal breakdown

Let’s dive a little deeper into what you can expect month by month.

The dry season (February to August)

This season is all about sunshine and warmth.

Month	Temp High (Avg. °C)	Rain Days (Avg.)	Key Weather & Activity Tips
February – April	26°C – 31°C	4−6	This period is generally sunnier and easier for outdoor sightseeing than the later wet season. Conditions still vary by day, so check the live forecast before fixed outdoor plans.
May – August	33°C – 35°C	7−11	These are the hottest months. The sun can be very intense, and the UV index is high. This is fantastic beach weather, but it requires you to take precautions like using lots of sun protection and staying hydrated.

The rainy/wet season (September to January)

This season is cooler, wetter, and brings with it the risk of tropical storms.

Month	Temp High (Avg. °C)	Rain Days (Avg.)	Key Weather & Risk Factors
September	30°C – 32°C	15	This is the transition month. The amount of rainfall increases sharply, and you can expect more frequent showers.
October – November	27°C – 29°C	15−21	These are the peak rainy months. This is when there is the highest risk of heavy rain, tropical storms (typhoons), and flooding. Be prepared for potential travel disruptions.
December – January	25°C – 26°C	10−18	This is the coolest period, what we call the Hoi An “winter.” It can feel damp, overcast, and a bit chilly, especially in the evenings, though it’s not cold by Indian winter standards.

Important traveler warnings: Typhoon, flood and UV risk

It’s very important to be aware of a few key weather risks when planning your trip.

Typhoon and Flood risk (Peak: October – November)

Does Hoi An experience typhoons? Yes, it can.

• Typhoon season: The peak season for tropical storms to affect our coast is from October to November. These storms can bring very strong winds and heavy rain, which may lead to travel delays, such as flight cancellations at the Da Nang airport.
• Flooding in Ancient Town: The beautiful, low-lying Ancient Town is located right next to the Thu Bon River and is prone to flooding during periods of heavy rain, especially in October and November.
• What to expect: Sometimes, the floods can be quite severe, and the ancient streets become waterways where locals travel by small boats (ghe). If you travel during this time, you must have a flexible itinerary and it may be wise to choose accommodation on higher ground. It is an interesting and unique sight, but it requires preparation.

Daily patterns and UV safety

• Daily patterns: Even in the rainy season, it usually doesn’t rain all day, every day. Often, the mornings can be clear, with heavy showers arriving in the afternoon or evening.
• UV safety: The UV index in Central Vietnam is consistently high, even on cloudy days. It is especially intense from May to August. Sun protection is not optional; it is necessary year-round. Always use high-SPF sunscreen, wear a hat, and seek shade during the peak sun hours of 10:00 AM to 3:00 PM.

Practical tips for visitors

So, what should you pack and how should you plan for each season?

Season	Clothing & Packing Tips	Activity & Planning Tips
Dry Season (Feb – Aug)	Pack lightweight, breathable fabrics like cotton and linen. Bring high-SPF sunscreen, sunglasses, and a wide-brimmed hat. A light rain jacket is a good idea for the occasional brief shower.	This is the time for all outdoor activities: relaxing on the beach, cycling through the countryside, and exploring the My Son Sanctuary. Many of Hoi An’s vibrant cultural festivals also take place during this period.
Rainy Season (Sep – Jan)	Pack clothes made from quick-dry fabrics (avoid heavy denim, which takes a long time to dry). A good waterproof jacket, an umbrella, and waterproof footwear are essential. For the coolest months (Dec/Jan), packing a light sweater or jacket for the evenings is a good idea.	This is the perfect season for indoor activities like visiting a tailor shop, taking a cooking class, or exploring Hoi An’s wonderful cafes. Always monitor the real-time weather forecasts for any typhoon warnings, and be prepared to use your travel insurance if needed.
General Tips	Stay hydrated! The high humidity can be draining, so drink plenty of water. It’s also always a good idea to carry cash, especially small bills, for local vendors.	If you are traveling during the typhoon season, it is very wise to book accommodation and transport with flexible or refundable policies. The cultural life of Hoi An continues, but event schedules may change due to the rain.
