1. Best Time: February to April

The months between February and April offer the most pleasant weather for a visit to Hoi An. During this period, you can expect mild temperatures ranging from 22°C to 30°C (72°F to 86°F) with low humidity and minimal rainfall. The dry season is in full swing, making it an ideal time for outdoor activities like exploring the UNESCO-listed Old Town, cycling through the countryside, or taking a boat ride along the Thu Bon River.

This period is also when Hoi An is at its liveliest, with a range of cultural festivals and events happening throughout the town. The weather is perfect for enjoying Hoi An’s beautiful beaches, like An Bang or Cua Dai, and strolling along the riverfront to see the colorful lanterns that light up the town at night.

2. Shoulder Season: May to August

While May to August brings warmer weather, it’s still a good time to visit Hoi An, especially for beach lovers. The temperatures rise to 28°C to 35°C (82°F to 95°F), and humidity levels increase. Although there can be some occasional rain showers, they are usually brief and don't last long, so you can still enjoy your activities.

During this time, the town’s beaches are less crowded, and you can take full advantage of the sunny days for swimming, sunbathing, or water sports. If you don’t mind the heat and prefer a quieter experience without the peak-season crowds, this period offers a great balance between good weather and fewer tourists.

3. Rainy Season: September to January

September to January marks the rainy season in Hoi An, with October being the wettest month. During this time, expect heavy showers and high humidity. Temperatures range from 22°C to 28°C (72°F to 82°F), which can still feel warm despite the rain. Flooding is a risk in October and November, as the town is located along the river, and downpours can cause disruptions to some outdoor activities.

However, visiting during the rainy season does have its perks. The town is less crowded, which means you can explore the ancient streets without the typical tourist crowds. If you don’t mind the rain, the quieter atmosphere allows for a more peaceful experience. Plus, the lush greenery around Hoi An looks even more stunning after a rainfall. And don’t forget — Hoi An's cozy cafes and restaurants are perfect for relaxing with a hot drink or enjoying some local delicacies when the rain falls.

4. Special Events: Hoi An Lantern Festival

One of the highlights of Hoi An is its Lantern Festival, which takes place on the 14th day of each lunar month. During this time, the ancient town transforms into a magical sea of colorful lanterns. The streets are filled with live music, traditional performances, and cultural activities. If you’re in Hoi An during a full moon, be sure to join in the celebration, as the town is beautifully illuminated, creating an unforgettable experience.
