Hoi An is a lantern-lit riverside town on Vietnam's central coast where centuries of international trade left behind a beautifully preserved Ancient Town, now a UNESCO World Heritage site. Chinese, Japanese, and European merchants shaped its architecture from the 15th century onward, and that legacy lives on in timber-framed houses, ornate assembly halls, and the iconic Japanese Covered Bridge. Today, Hoi An is equally famous for its food: cao lau noodles made with water drawn from a specific ancient well, crispy banh xeo pancakes, delicate white rose dumplings, and what many consider Vietnam's finest banh mi. Add custom tailoring shops on every corner, cooking classes in countryside kitchens, bicycle rides through emerald rice paddies, and a monthly full-moon lantern festival that turns the Thu Bon River into a floating gallery of light, and you have a place that rewards slow travel like few others in Southeast Asia.
Your ideal window for Hoi An runs from early December through late February. Temperatures feel perfectly comfortable, with highs of 77.9°F (25.5°C) and lows of 67°F (19.4°C), making it easy to spend full days walking the Ancient Town, cycling to Tra Que vegetable village, and lingering over bowls of mi quang at open-air restaurants. Rain does show up regularly (roughly 3 to 5 days per month with significant showers), but the downpours are typically short-lived. This window also overlaps with Tet, Vietnam's Lunar New Year, which usually falls in late January or February and fills Hoi An's streets with fireworks, lantern displays, and traditional performances. Keep in mind that December is the town's busiest month, so book accommodation well ahead. If you'd rather dodge crowds and don't mind heat, spring (March through May) is a strong secondary option: it's one of the driest stretches of the year with far fewer visitors and lower room rates.
Spring in Hoi An, Vietnam
Spring is when Hoi An dries out and heats up. February is one of the driest months of the year, with only about a 4% chance of significant rain on any given day, and March and April stay similarly dry. That makes this the best stretch for cycling out to An Bang Beach, a peaceful sandy stretch about 7 km from the Ancient Town where beachfront shacks serve grilled seafood and cold beer. Afternoons warm to seasonal highs of 88.1°F (31.2°C), hot enough that you'll appreciate a midday pause at one of Hoi An's excellent coffee shops, where iced coconut coffee goes down as a cold, creamy reward.
Mornings are the time to explore. Lows sit at 74.1°F (23.4°C), which feels pleasant before the sun climbs, so aim to visit the Phuc Kien Assembly Hall, Tan Ky House, and the Japanese Covered Bridge early. The car-free Ancient Town is best covered on foot or by bicycle. If you've been thinking about getting something custom-tailored, Hoi An's reputation as the textile capital of Vietnam is well-earned: the town has a long tailoring tradition, and skilled shops can turn around a suit or dress in a couple of days. Tourism is fairly slow in spring, meaning shorter waits at restaurants and better deals on accommodation.
Late April brings Reunification Day and early May has Labour Day, which can cause a short domestic travel surge. Pack lightweight, breathable clothing, a good sun hat, and reef-safe sunscreen if you plan on snorkeling at the Cham Islands, a group of eight small islands offshore with coral reefs and clear water.
Summer in Hoi An, Vietnam
Summer pushes Hoi An into serious heat. Seasonal highs average 94.3°F (34.6°C), and late June brings peak temperatures topping out at 96.7°F (35.9°C) with overnight lows of 78.8°F (26°C). Humidity drops to its annual low in June, but the sheer temperature makes midday sightseeing exhausting. Plan outdoor activities for early morning or late afternoon instead. Sunrise comes before 5:30 AM, so an early bike ride through the rice paddies toward Cam Thanh and Tra Que vegetable village lets you see Vietnamese countryside life before the heat sets in.
Rain stays relatively modest, with roughly 1 to 3 days of significant showers per month, far less than the fall deluge. That dry heat opens up the beach: An Bang and Cua Dai are at their best for swimming, and boat trips to the Cham Islands for snorkeling run regularly. Evenings cool down enough for a sunset cruise on the Thu Bon River, and the monthly Full Moon Lantern Festival, held on the 14th day of each lunar month, transforms the Ancient Town when electric lights are switched off and hundreds of paper lanterns float on the water. Summer is the second busiest tourism season, with room rates running slightly above average.
Lows still hover at 77.8°F (25.5°C) after dark, so pack the lightest fabrics you own. A reusable water bottle is essential: you'll go through liters of water walking the cobblestone streets. Cooking classes, which typically start at a market visit and end with a meal you've prepared, are a smart way to spend the hottest hours under a covered kitchen rather than in the open sun.
Fall in Hoi An, Vietnam
Fall is Hoi An's wet season, and the rain arrives with purpose. Precipitation is consistently present, with roughly 3 to 5 days of significant showers each month. October is the wettest month of the year, with a 49% chance of rain on any given day, and November stays nearly as wet. The Thu Bon River can rise dramatically, and occasional flooding sends water into the lower streets of the Ancient Town. If you visit in fall, check conditions before booking and bring waterproof bags for electronics.
The upside is that this is the quietest tourism season in Hoi An, with November being the least visited month of the year. Accommodation is priced affordably, and you'll have restaurants, cooking classes, and tailor shops largely to yourself. Seasonal highs of 85.9°F (29.9°C) feel gentler than summer, and lows of 73.7°F (23.2°C) bring some relief in the evenings. The Mid-Autumn Festival, which falls on the 15th day of the 8th lunar month (typically in September or October), turns Hoi An into a street carnival with lantern parades, lion dances, and community feasts, so timing your trip for that event could be rewarding.
Winds pick up across the season, and late October into early November sees the strongest gusts of the year. Cham Island boat tours may be cancelled on rough-weather days, so keep your itinerary flexible. A packable rain jacket and quick-dry shoes will serve you better than an umbrella in heavy downpours. The Hoi An Memories Show, a large-scale outdoor performance at Hoi An Impression Theme Park featuring over 500 performers recreating 400 years of local history, runs regularly and is a good option for rainy evenings.
Winter in Hoi An, Vietnam
Winter is when Hoi An hits its stride for visitors. Temperatures feel perfectly comfortable: highs of 77.9°F (25.5°C) and lows of 67°F (19.4°C) make all-day exploration pleasant without the punishing heat of summer. Mornings can feel genuinely cool by Vietnamese standards, so bring a light layer for early walks through the Ancient Town. Rain does come regularly, with roughly 3 to 5 days of significant precipitation per month. December is wetter than January or February, but showers tend to pass quickly.
Tet, the Vietnamese Lunar New Year, typically falls in late January or mid-February and transforms Hoi An. The town fills with fireworks, traditional performances, and lantern-lit streets, and local markets overflow with kumquat trees, flowers, and festive snacks. Be aware that some family-run restaurants and shops close for the first few days of Tet, and prices at hotels and services may carry a holiday surcharge. Booking well ahead is essential: December is Hoi An's busiest month for tourism, and the weeks around Tet see a domestic travel surge as well.
This is a great season for the My Son Sanctuary, a UNESCO-listed complex of ancient Cham temples about an hour's drive from town, where early-morning visits let you explore misty jungle ruins in cool air. Back in Hoi An, shorter days (the sun sets around 5:15 PM in December) mean the evening lantern atmosphere starts earlier, giving you more time to browse the Night Market along Nguyen Hoang Street, release a floating lantern on the river, or settle into a riverside seat for a bowl of cao lau as the Ancient Town glows around you.

Travel Tips & Safety for Hoi An, Vietnam
Hoi An doesn't have its own airport. Fly into Da Nang International Airport, which receives domestic flights from Hanoi and Ho Chi Minh City as well as regional international routes. The drive from Da Nang to Hoi An takes about 40 to 50 minutes, and you can arrange a hotel pickup or use the Grab ride-hailing app. Within town, the Ancient Town is car-free, so walking and cycling are the way to go. Bicycles are available at most hotels and rental shops for very little.
Traffic in Vietnam can feel chaotic, so stay alert when crossing roads, especially outside the pedestrian-friendly Old Town. Petty theft can occur in crowded areas like markets and festivals; keep valuables in a front bag or money belt. Tap water is not safe to drink, so stick with bottled or filtered water and be cautious with ice from street stalls. The Vietnamese dong is the local currency, and while many restaurants accept cards, smaller vendors and market stalls operate on cash only, so keep small bills handy.
