Ha Long Weather in October

October weather on the bay

October feels warm and damp, with highs around 28°C and evenings near 22°C. Humidity stays high, and rain falls on about 12 days, though showers don't usually take up the whole day. It's a welcome change from September's heavier rain, but the sky can still look cloudy.

A boat trip through Ha Long Bay is still a good fit, and the milder heat makes time around Bai Chay more comfortable than in summer. Keep flexible plans for kayaking or swimming: rain and cloud can make time on the water less appealing. For clearer, drier weather, December to February is a better bet.

Crowds, costs and October dates

October is generally quieter than the busy summer holiday months, when Vietnamese families visit the coast. You're likely to find a calmer feel around Bai Chay and less pressure on popular boat trips. Prices can ease after summer, though weekends and school breaks may still bring local visitors.

October 20 is Vietnamese Women's Day, a national occasion when people often give gifts or flowers. It isn't a major Ha Long festival, but you may notice special displays in shops and restaurants. The Mid-Autumn Festival sometimes falls in October, depending on the lunar calendar; when it does, look for lanterns and mooncakes.

A useful Ha Long tip

For the classic bay scenery, choose a cruise that visits Sung Sot Cave, one of the area's best-known stops. Rain can leave the cave approach and steps slippery, so take your time there. If the weather turns, the cave is still a worthwhile stop, while an exposed kayak trip may be less pleasant.

Families who prefer gentler heat may find October easier than the summer school-holiday rush, but keep a rainy-day plan for time ashore. A meal of cha muc, Ha Long's minced squid cake, is a local treat to seek out around Bai Chay.
