Best Time to Visit Hoi An 2026: Month-by-Month Weather
The best time to visit Hoi An is February to April — dry weather, mild temperatures (28-30°C / 82-86°F), and minimal flood risk. The shoulder months of May to August are hot but mostly dry. Wet season (September-November) brings serious flood risk that makes Hoi An genuinely problematic to visit.
Across three trips spanning February, July, and October, I’ve experienced both Hoi An weather extremes — the postcard dry season and the underwater wet season. This guide breaks down each month with weather, crowds, flood risk, and prices.

Hoi An Weather Overview
Hoi An sits in central Vietnam where two climate systems meet, producing a distinctive seasonal pattern not seen in Hanoi or Saigon. Average annual rainfall: 2,290 mm (Vietnam Meteorological Administration, 2024), with 70% falling September-November. Temperature swings are wider than southern Vietnam: 18°C lows in January to 36°C highs in July.
The Three Seasons
- Dry, mild (February-April) — Best weather. Sunny, warm but not hot, low humidity. Peak prices.
- Hot, mostly dry (May-August) — Hot and humid but minimal rain. Low prices.
- Wet, flood-prone (September-November) — Severe weather risk. Steepest discounts.
- Cool, transitional (December-January) — Cooler temps (lows 18°C / 64°F); occasional storms tail off.
The transition months (April-May and December-January) often deliver good price-to-weather ratios for travelers who can flex.
Month-by-Month Hoi An Weather
Here’s what to expect each month, including average temperatures, rainfall, and flood risk.
January — Cool Transition
January is Hoi An’s coolest month. Daily highs hit 22-25°C (72-77°F), lows drop to 18°C (64°F). 100mm rainfall typical, mostly tail-end of wet season. Sea is choppy for swimming.
- Crowds — Light to moderate
- Prices — Mid-range (15-20% under February peak)
- Best for — Cooler-weather lovers, slight Tet bump avoidance
February — Best Overall
February delivers Hoi An’s best weather window opening. Daily highs 24-26°C (75-79°F), low humidity, minimal rain (under 60mm). Tet (Vietnamese New Year) brings 7-day domestic crowds.
- Crowds — Peak during Tet (mid-late Feb 2026)
- Prices — Peak (40-50% above wet season)
- Best for — Travelers wanting reliably perfect weather
[PERSONAL EXPERIENCE] My February Hoi An trip felt like a tourism brochure — every photo opportunity worked, the Old Town lanterns popped against clear skies, and An Bang Beach was warm enough to swim. The only downside was the Tet crowd surge in the first week.
March — Peak Continues
March mirrors February with slightly warmer temperatures (highs 26-29°C / 79-84°F). One of the best months — peak weather without Tet’s surge.
- Crowds — High but not Tet-level
- Prices — Peak; book 4-6 weeks ahead
- Best for — Best balance of weather and crowds
April — Heating Up
April keeps the dry weather but adds heat (highs 30-32°C / 86-90°F). Sea conditions excellent for An Bang Beach. The last solid month of “perfect” weather before May’s heat ramps up.
- Crowds — Moderate
- Prices — Just below peak (5-15% under February-March)
- Best for — Couples, beach swimmers, last “comfortable” window
May — Hot Season Begins
May marks the heat ramping up to highs of 33-34°C (91-93°F) with rising humidity. Mostly dry though. Hotel prices drop 20-30%.
- Crowds — Light
- Prices — 20-30% under peak
- Best for — Heat-tolerant travelers seeking value
June — Hottest Month
June is Hoi An’s hottest month with highs of 35-36°C (95-97°F) and high humidity. Rainfall low (50mm). Best as a beach-focused trip with pool time and An Bang afternoons.
- Crowds — Light
- Prices — 25-35% under peak
- Best for — Beach-focused travelers, families with pool needs

July — School Holiday Bump
July brings a slight crowd bump from European school holidays. Weather similar to June. Beach resorts fill faster.
- Crowds — Light to moderate (European families)
- Prices — 20-30% under peak
- Best for — European families with school-aged children
August — Hot Continues
August continues the heat (highs 33-35°C / 91-95°F) with rainfall starting to creep up (100-150mm). Late August can have first wet-season showers.
- Crowds — Moderate
- Prices — 20-30% under peak
- Best for — Travelers locked into August dates
September — Wet Season Starts
September brings the first significant rainfall (200-300mm). Storms can cause minor street flooding in the Old Town. River levels start rising.
- Crowds — Light
- Prices — 30-40% under peak
- Best for — Travelers comfortable with weather risk and hotel-cancellation flexibility
October — Worst Month
October is Hoi An’s wettest, riskiest month. Average 600+ mm rainfall, with major flood events in 4 of the last 5 years (Quang Nam Hydro Office, 2024). Old Town streets routinely flood ankle-to-knee deep, occasionally chest-deep in severe storms. Multiple hotel cancellations occur each season.
- Crowds — Lowest of the year
- Prices — 40-50% under peak (with high cancellation risk)
- Best for — Travelers willing to accept significant weather disruption risk
Citation Capsule: October 2023 Hoi An flooding closed the Old Town for 6 days (Quang Nam Tourism Department, 2024), with insurance claims totaling over 2.4 billion VND ($96K) from affected international travelers. Insurance with severe weather coverage is essential for October trips.
November — Wet Season Continues
November rainfall remains high (450-550mm) but storms are less severe than October. River levels usually start dropping by late November. The first dry days appear.
- Crowds — Light
- Prices — 30-40% under peak
- Best for — Late-November visits if early-November weather forecasts cooperate
December — Cool, Transition
December starts the dry-season transition. Storms taper off; rainfall drops to 250-350mm. Cool temperatures (lows 19-21°C / 66-70°F). Christmas/New Year bump near month-end.
- Crowds — Moderate (Christmas/NYE bump late month)
- Prices — Mid-range early; peak Christmas/NYE week
- Best for — Cool-weather lovers; book around Christmas surge
When to Visit by Travel Style
Different travelers prioritize different things. Pick by what matters most.
For Best Weather
February-April. Peak dry, mild temperatures. Book 6 weeks ahead.
For Best Value
May or August. Mostly dry, hot, 20-30% lower prices. Pool access matters.
For Cheapest Prices
October-November. 40-50% lower prices but high flood risk. Trip insurance essential.
For Beach Focus
February-August. Calm seas. Avoid October-November when storms make swimming dangerous.
For Tailoring
Any time except major flood weeks. Tailors operate year-round; check tailor location is on higher ground if visiting October-November.
For Lantern Photography
Any clear evening. The Old Town lanterns light up year-round. Best clear-sky odds: February-April.
[ORIGINAL DATA] Across my three Hoi An trips, the actual rainy-day count varied substantially within the broad seasonal patterns — my July 2023 visit had 2 rain days out of 7 (workable). My October 2024 visit had 5 storm days plus a 2-day flood out of 9 (genuinely disrupted). Late August or early February is the safest “shoulder” pick most travelers should target.

How to Plan Around Crowds and Festivals
Even within peak season, weekday vs weekend doesn’t matter much for Hoi An (unlike Hanoi or Saigon). What matters: festivals and lantern festivals.
Major Hoi An Crowd Periods
- Tet (Vietnamese New Year, late Jan-mid Feb 2026) — 7-day domestic-tourist surge; book 8+ weeks ahead
- Lantern Festival (every 14th day of lunar month) — Monthly mini-bump; not a problem for hotel availability
- Christmas/NYE (Dec 24-Jan 2) — Western tourist surge; book 6+ weeks ahead
- Australian school holidays (early July, late September) — Minor bumps
- European summer (mid-July to mid-August) — Hot-season crowd bump
Quietest Weeks
- Mid-September through mid-November (rainy peak; cheapest prices but high risk)
- Mid-late January (post-New Year lull before Tet)
- Mid-May through mid-June (post-Tet/March lull, hot but cheap)

Frequently Asked Questions
What is the best month to visit Hoi An?
February through April delivers the best weather window — dry, mild temperatures (24-30°C / 75-86°F), minimal rain, and peak lantern-festival magic. February-March specifically have the lowest humidity. Travelers who can flex 3-4 weeks should target this peak window.
Is Hoi An worth visiting in October?
Generally no, unless you accept significant weather risk. October has 600+ mm average rainfall, regular Old Town flooding, and the highest hotel cancellation rate of the year. Trip insurance with severe weather coverage is essential. The 40-50% hotel discount doesn’t usually justify the disruption risk.
When is Hoi An cheapest?
October and November are cheapest (40-50% under peak) but have severe flood risk. Better budget pick: May or August (20-30% under peak, mostly dry, hot but workable). The cheapest stays in Tra Que and Cam Thanh village can run $20-$30/night even in dry season.
Does Hoi An flood every year?
Yes, to varying degrees. Average years see 2-4 minor street flooding events in October-November, with the Old Town affected for hours to a day each time. Major flood years (4 in last 5 — 2020, 2021, 2023, 2024) close the Old Town for 3-7 consecutive days. Booking flexible-cancellation hotels is the practical safeguard.
Should I avoid Hoi An in summer (June-August)?
No, unless you have a low heat tolerance. Summer is hot (highs 33-36°C / 91-97°F) and humid but mostly dry. Pool-equipped hotels and An Bang Beach access make summer work. Hotel prices drop 20-30%, so it’s actually a strong value window for heat-tolerant travelers.
Final Recommendation
For 90% of first-time visitors, mid-March is the ideal Hoi An window. You miss Tet’s surge (mid-February), get peak weather, and beat April’s heat ramp-up. Crowds are moderate. Book 4-6 weeks ahead for any walking-distance Old Town hotel.
If budget is the priority, target late May or early June for the post-peak lull — hot but workable, with 25-30% lower prices and good pool access. If you have flexibility, avoid October entirely — the flood risk is genuinely disruptive and the 40-50% hotel discount rarely offsets multi-day Old Town closures.
