This period lasts for about seven months, with temperatures gradually rising, mostly clear skies, and minimal rainfall. From February to April, the weather is mild, with average temperatures ranging from 24°C to 28°C. Conditions are generally dry, with light breezes and relatively low humidity, making this one of the coolest and most comfortable times of the year.

From May to August, Central Vietnam begins to experience intense heat waves. Daytime temperatures remain consistently high, often reaching 35°C to 38°C around midday. Solar radiation and UV levels also peak during these months, contributing to hot and humid conditions.

• Average temperature: Ranges from around 24°C at the beginning of the season and can exceed 38°C during the hottest months.
• Rainfall: Heavy rain is rare, with average monthly rainfall generally remaining below 100 mm.
• Humidity and sunshine: Humidity levels drop considerably, while Hoi An receives around 10 to 12 hours of sunshine per day.

The rainy season brings more unpredictable weather and accounts for around 75% of Hoi An’s annual rainfall. From September to November, tropical storms and low-pressure systems are most active. Heavy rain can continue for several days, with monthly rainfall sometimes exceeding 500 mm. Intense rainfall combined with floodwater flowing downstream from upstream areas can frequently cause severe flooding.

In December and January, tropical storms become less frequent, but the region is increasingly affected by the northeast monsoon. Temperatures drop to around 19°C to 22°C, creating noticeably cooler conditions. Skies are often cloudy and overcast for extended periods, with light drizzle and occasional early-morning fog.

• Average temperature: Gradually falls from around 28°C in September and can drop below 19°C during the coldest periods in January.
• Rainfall: Extremely high, often concentrated in heavy downpours and thunderstorms, with a significant risk of storms, flooding, and waterlogging.
• Sea conditions: Strong winds, high waves, and rough seas are common due to the alternating influence of tropical storms and the northeast monsoon.

The cool, dry weather at the beginning of the year is ideal for walking tours and cycling trips around Hoi An. Exploring the Old Town on foot is especially pleasant, as you can spend more time outdoors without feeling exhausted by the heat. Along Tran Phu Street, you can take your time admiring the architectural details of landmarks such as the Japanese Covered Bridge and the Fujian Assembly Hall.

Cycling through the countryside surrounding Hoi An is another experience worth adding to your itinerary. The mild weather makes outdoor activities much more enjoyable, especially when visiting traditional craft villages and interacting with local residents.

• Walk around Hoi An Ancient Town: The gentle sunlight makes sightseeing more comfortable and is also ideal for taking clear architectural photos without harsh glare.
• Try pottery making in Thanh Ha Pottery Village: The open-air setting and dry weather create comfortable conditions for shaping clay and trying a traditional pottery wheel.
• Experience farming in Tra Que Vegetable Village: Spring is a great time to cycle to the village, when the air is fresh and the vegetable gardens are at their greenest and most vibrant.

2.2. April to August: Enjoy the Beaches and Outdoor Activities

The high temperatures and long hours of sunshine in summer make this the best time for beach and island activities. Early mornings and late afternoons are ideal for relaxing by the sea, swimming, or trying water sports. Beaches such as An Bang and Cua Dai also offer a wide range of recreational activities and services.

This is also the time of year when the waters off Central Vietnam are generally calmer, creating favorable conditions for high-speed boat trips. Strong sunlight and clear seawater provide excellent visibility, making it easier to observe marine life beneath the surface.

• Swimming and SUP boarding at An Bang Beach: The cool seawater offers a refreshing escape from the summer heat, while the relatively calm surface makes it suitable for beginners learning to paddleboard.
• Snorkeling at Cu Lao Cham: Calm seas and excellent underwater visibility allow visitors to fully appreciate the colorful coral reefs and rich marine ecosystem.
• Watch the Hoi An Memories Show: Clear and dry summer evenings provide ideal conditions for this large-scale outdoor performance, with a lower chance of disruption from sudden rain.

2.3. September to December: Discover Local Culture and Cuisine

Frequent heavy rain toward the end of the year can make getting around more difficult, but it also creates an ideal opportunity to explore Hoi An’s culture through indoor experiences. On cool, rainy days, the Old Town takes on a slower and quieter atmosphere, offering a very different experience from the lively summer months.

Joining a cooking class is one of the most popular activities during the rainy season. Local chefs guide you step by step through the preparation of well-known regional specialties. It is a great way to stay dry while gaining a deeper understanding of Central Vietnamese cuisine.

• Join a cooking class: Indoor cooking schools provide a comfortable place to escape the rain. Enjoying a hot bowl of mi Quang or cao lau that you have prepared yourself is especially satisfying in the cool weather.
• Enjoy coffee while watching the rain: Rooftop and upper-floor cafés along the Hoai River offer a peaceful setting and beautiful views over the Old Town, often without the crowds found during peak season.
• Make a traditional lantern: At local craft workshops, you can learn the careful process of making a Hoi An lantern. This hands-on activity is a relaxing way to spend a rainy day and gives you a meaningful handmade souvenir to take home.

Packing according to the actual weather conditions in Hoi An can help you travel more comfortably and avoid unnecessary expenses. Choosing the right clothing and accessories also ensures a smoother experience, whether you visit during hot, sunny days or the cooler rainy season.

3.1. Clothing for the Dry Season

With temperatures often exceeding 30°C from February to August, breathable and moisture-wicking fabrics should be your top priority. Light-colored clothing is also recommended, as it absorbs less heat and helps you stay more comfortable during outdoor activities.

• Best fabrics: Linen, 100% cotton, and silk are ideal choices for keeping your skin cool and allowing sweat to dry more quickly.
• Comfortable styles: Lightweight T-shirts, shorts, and maxi dresses provide plenty of comfort for long cycling trips, sightseeing, or spending time at the beach.
• Sun protection accessories: Be sure to pack UV-protection sunglasses, a wide-brimmed hat, and a lightweight outer layer to protect your skin from strong sunlight.

3.2. Essentials for the Rainy Season

From September to January, Hoi An experiences more frequent rain and cooler temperatures. Staying warm and keeping personal electronics protected from moisture should be a priority to help ensure your trip goes smoothly.

• Waterproof essentials: A lightweight raincoat or compact umbrella is a must-have item to keep in your day bag.
• Warm clothing: Pack a water-resistant windbreaker, a light sweater, or a scarf to stay comfortable during cool early mornings and late evenings, especially when the northeast monsoon is stronger.
• Protect electronic devices: Bring waterproof zip bags or protective pouches for your phone, camera, and power bank to prevent moisture from damaging your devices.

3.3. Suitable Footwear for Sightseeing

Motorized vehicles are restricted in much of Hoi An Ancient Town, so visitors often spend several hours walking on paved streets and may cover 5 to 10 km a day. Choosing the right footwear can make a major difference in comfort and help reduce foot fatigue throughout the trip.

• Sneakers: Shoes with soft soles and cushioned insoles provide good support and are ideal for spending several hours walking around the Old Town.
• Sandals with back straps: These offer better ventilation and a secure fit, making them suitable for walking on the sand at An Bang Beach or cycling along riverside routes.
• Non-slip waterproof shoes: A practical choice during the rainy season, especially when streets are wet or flooded. Waterproof rubber materials provide better grip on slippery stone surfaces and are also easy to clean afterward.
