Hoi An Weather in April

The weather of Hoi An in April is not favorable, as it becomes quite hot. Combined with high humidity, it doesn’t feel comfortable. Furthermore, the UV index is extremely high. Yet it has a key advantage: April remains in the dry season with very low rainfall, so travel plans are rarely disrupted. With proper sun protection and by avoiding the hottest hours of the day, you can still enjoy a good trip.

High Temperatures

In April, Hoi An experiences relatively high temperatures, and the climate can sometimes be scorching hot. Fortunately, early mornings and evenings stay comfortably mild, leaving ample time for outdoor activities.

Daily high temperatures mostly range from 28 to 33 degrees Celsius (82 - 91 degrees Fahrenheit), and with humidity close to 90%, you’ll feel a constant layer of warm, damp moisture clinging to your skin. When visiting indoor attractions without air conditioning, such as the Quang Trieu Assembly Hall, you’ll feel stuffy - the air seems still, as if it has stopped moving entirely. Occasionally, temperatures can soar to 40℃ (104℉). On days like this, it’s barely fit to go out; you’ll be soaked all over in just a few minutes.

Nighttime low temperatures typically hover between 22 and 26℃ (72 - 79℉), turning the area into a natural air-conditioned room. At this time, you can wander the ancient town for two to three hours straight without worrying about breaking a heavy sweat. Best of all, gentle breezes drift through the alleyways now and then, bringing a refreshing touch of coolness.

Infrequent Showers

April falls in the middle of the dry season, with very low rainfall: the average monthly precipitation is only 34 mm, and there are about 10 rainy days in total. The rain usually does not last long and will not keep you indoors for extended periods; nor does it occur frequently, so it will not repeatedly interrupt your itinerary and force you to take shelter from the rain.

Yet you shouldn’t disregard the rain entirely: showers here are often intense. If you plan to visit sites like My Son Sanctuary, a sudden downpour can quickly make paths muddy and hard to traverse. So be sure to check the weather forecast before setting off, and try to avoid visiting these mountains and valleys around rainy periods.

Prolonged Daylight / Sunshine Duration

In Hoi An during April, the sun rises at around 5:32 and sets at around 18:02. Daylight lasts a full 12.5 hours, well over half the day. Even if you want to stay indoors to escape the midday heat, you will still have plenty of time for outdoor activities before 10:00 AM and after 3:00 PM.

In addition, Hoi An enjoys an average of 7 hours of sunshine daily in April, leaving most of the day clear and brightly lit. You can avoid the harsh midday sun overhead to photograph the ancient town’s bright yellow buildings, as well as the sunrises and sunsets along the Thu Bon River. The soft, gentle light at these times produces clear, vivid, and stunning photographs.

However, it’s important to note that in April, Hoi An’s UV Index reaches 11 or higher, extremely intense. Without proper sun protection when going out, you can get sunburned in a short time. Especially in waterfront areas, UV rays reflect and refract from all directions, so full-coverage sun protection is essential.

Packing List for Visiting Hoi An in April

Clothes: Mainly pack lightweight, breathable summer clothing. For instance, men can bring short-sleeved T-shirts, short-sleeved shirts, shorts, and thin pants; women may opt for dresses, skirts, and tank tops. As you may sweat a lot and need to change clothes frequently, bring a few extra changes; anyway, summer garments are light and take up a little space.

Shoes: The climate is hot and humid, so opt for breathable footwear such as sandals or slippers. If you’re worried about tired feet from walking long distances in these shoes, you can also pack a pair of sneakers - preferably thin, lightweight ones.

Others: Sunscreen, sunglasses, sun hats, parasols, and etc.

How to Have a Good Tour in Hoi An in April

1. Plan activities such as exploring the ancient town, trekking through rice fields, and cycling outdoors between 5:30 - 9:30 and 15:30 - 20:00, avoiding extreme heat and strong UV rays from 10:00 to 15:00. Take a midday break to cool off.

2. Most attractions and streetside shops in the Hoi An ancient town have no air conditioning. It’s best to carry a portable fan and cooling patches with you, as they can quickly relieve stuffiness and reduce the risk of heatstroke.

3. To handle April’s high humidity, prioritize accommodations with a balcony, excellent ventilation, and air conditioning featuring a dehumidifying function. This helps dry your laundry faster and keep clothes from developing musty odors.

4. When visiting Hoi An in April, we highly recommend you don’t miss An Bang Beach and the Thu Bon River. With pleasantly warm sea water, gentle waves, and calm, rapid-free currents, this is the perfect time to go snorkeling, wade in the surf, take a scenic boat ride, and unlock an exceptional waterfront experience.
