Northern Vietnam climate

Travel tips for August in North Vietnam
August remains a hot and humid month in North Vietnam, with frequent rainfall, especially in the afternoons. While some regions experience heavy downpours, there are still opportunities for exploration if you plan accordingly. Here’s how to prepare for traveling in August.
- What to bring – Light, breathable clothing is essential due to the heat and humidity. Pack a rain jacket or a compact umbrella for sudden showers. High-SPF sunscreen, a hat, and sunglasses are necessary for sun protection. Mosquito repellent is also recommended, especially in rural and forested areas.
- Accommodation – August is still part of the peak domestic travel season, particularly in Ha Long Bay and Ninh Binh, where Vietnamese families continue their summer vacations. Expect higher prices and busier tourist spots, especially in the first half of the month. If you prefer quieter travel, book accommodations in less crowded areas or visit toward the end of the month.
- Homestays – The heat and humidity make homestays in the mountains less comfortable, as most do not have air conditioning. Nights in Sapa and Ha Giang may be cooler than in Hanoi, but it can still feel warm indoors. Choose a homestay with good ventilation or a fan if available.
- Outdoor activities – Trekking in Sapa and Ha Giang is more challenging due to heat and occasional heavy rain, which can make trails slippery. The rice terraces remain green and are approaching their most stunning phase. Ha Long Bay and Ninh Binh boat trips are possible but expect cloudy skies and some rain. Check weather forecasts before booking, as storms occasionally disrupt cruises.
- Getting around – Due to the combination of heat and rain, walking long distances in Hanoi can be uncomfortable. Taxis and ride-hailing apps are better options for getting around the city. For long-distance travel, opt for air-conditioned buses, trains, or private cars instead of motorbikes, as roads can be wet and slippery.
- Heat-related tips – Avoid outdoor activities during midday when temperatures peak. Drink plenty of water, wear lightweight clothing, and take breaks in shaded or air-conditioned areas.
- Mosquito precautions – August’s humid conditions increase mosquito activity. Use repellent, especially in rural areas, and opt for accommodations with mosquito nets or air conditioning.
