This guide will take you through every season, its impact on activities, and practical tips to make your journey smooth and memorable.

Understanding Hai Phong Weather

Overview of Hai Phong’s Climate

Situated along Vietnam’s northern coast, Hai Phong enjoys a humid subtropical climate that is strongly influenced by both the monsoon winds and its proximity to the Gulf of Tonkin. Unlike tropical southern Vietnam, which tends to have only a wet and dry season, Hai Phong has four well-defined seasons: spring, summer, autumn, and winter.

Average temperatures range from a chilly 15°C in the winter to a hot and humid 33°C during the peak of summer. Rainfall is unevenly distributed, with the majority of it falling between May and September, which is considered the rainy season. This period coincides with Vietnam’s summer, marked by heavy showers, high humidity, and occasional tropical storms.

The remaining months are generally cooler, drier, and more comfortable for sightseeing. This variation makes Hai Phong a destination that offers different experiences depending on the time of year, which is why it is essential to plan according to Hai Phong weather.

Seasonal Breakdown

Spring (February–April): Mild Weather and Festive Spirit

Spring in Hai Phong is more than just a mild season—it is also the heart of cultural celebrations. February often coincides with Tet, the Lunar New Year, when families gather, streets are decorated with kumquat trees and peach blossoms, and temples overflow with worshippers. Travelers visiting during March and April can witness vibrant flower festivals, enjoy blooming flamboyant trees (Hai Phong is nicknamed the “City of Flame Trees”), and stroll along the Tam Bac River under fresh breezes. While drizzle might occasionally appear, it rarely interrupts outdoor plans. Instead, the misty air gives the city a poetic charm, perfect for photographers and romantic travelers.

Summer (May–August): Beaches and Bustling Energy

Though summer in Hai Phong is hot and humid, it is also the liveliest season for local tourism. Families flock to Do Son Beach, where seafood restaurants serve freshly caught crabs, prawns, and clams. Boats shuttle visitors to Cat Ba Island, where kayaking, snorkeling, and hiking in Cat Ba National Park attract adventurers. However, the sun can be relentless, so packing light cotton clothes, sunscreen, and hydration supplies is non-negotiable. Afternoon showers, while frequent, often cool the air and provide a refreshing break from the heat. For those who can embrace the warmth, summer delivers the most energetic version of Hai Phong.

Autumn (September–November): Golden Season for Exploration

Autumn is widely celebrated as the best time to visit Hai Phong. The crisp air makes cycling through rural villages and rice fields more enjoyable. The sea is calmer, ensuring safer and smoother ferry rides to Cat Ba and Lan Ha Bay. During October, travelers can explore Cat Ba National Park’s trails to witness foliage turning golden and red. With clear skies, it is also the perfect time for photography—sunsets over Do Son or the harbor skyline are simply breathtaking. Moreover, autumn evenings are cool enough for leisurely walks through the Old Quarter, where French-colonial buildings glow warmly under streetlights.

Winter (December–January): Culture and Cuisine Over Coastlines

While winter is not beach season, it holds its own unique appeal. Temperatures can dip to 12–15°C, making it one of the coldest coastal cities in Vietnam. Yet this is when Hai Phong’s culinary culture shines. Steaming bowls of crab noodle soup (bánh đa cua) or hot grilled bread with chili sauce become comforting staples. Foggy mornings create an almost European atmosphere, adding mystery to colonial-era villas and historic sites. Visitors can explore temples like Du Hang Pagoda or shop in bustling markets without sweating through their clothes. For culture-oriented travelers, winter is one of the most rewarding times to visit. 

How Hai Phong Weather Affects Travel Plans

Because of its varied climate, Hai Phong weather can directly influence your itinerary:

Rainy season (May–September): Heavy rainfall can disrupt beach outings, island excursions, or boat tours around Cat Ba and Lan Ha Bay. Outdoor sightseeing may also be cut short by sudden downpours.

Winter (December–January): Cold temperatures make swimming unappealing, but cultural exploration thrives in these months. You can comfortably visit temples, colonial architecture, and local markets without the discomfort of heat.

Summer (June–August): The intense heat demands precautions like sunscreen, hats, and hydration. It is also the season when insect activity increases, making repellents essential.

In short, tailoring your plans to the climate can turn potential obstacles into opportunities for unique experiences.

Best Time to Visit Hai Phong

Ideal Months for Sightseeing and Outdoor Activities

Two periods stand out as the best time to visit Hai Phong:

• September to November (Autumn): The weather is cool, skies are clear, and humidity is low. This makes it perfect for activities such as trekking in Cat Ba National Park, cycling along coastal roads, or enjoying lantern-lit evenings by the port.
• March to April (Spring): Temperatures are pleasant, and the city buzzes with festivals. This is also the flower season, when parks and boulevards are lined with colorful blossoms.

Both these windows offer the most reliable conditions for sightseeing, outdoor adventures, and photography.

When to Avoid (Weather-wise)

While Hai Phong can be visited year-round, there are two periods less favorable for travelers:

• July and August: Peak summer months bring intense heat and heavy rainfall. These are also the months with the highest risk of typhoons, which can temporarily halt ferry services to Cat Ba Island.

• December and January: Although not extreme, the cold, dry air can feel damp and chilly, particularly if you are expecting a tropical beach vacation. Coastal scenery appears less vibrant compared to warmer months.

Matching Travel Goals with Seasons

Your ideal best time to visit Hai Phong will depend largely on your interests:

• Beach lovers: Aim for late spring (April–May) or early autumn (September), when the sea is warm but rainfall is limited.
• Culture seekers: Winter and early spring are perfect for exploring pagodas, temples, and attending local festivals without worrying about heat.
• Nature enthusiasts: Spring bloom (March–April) and autumn foliage (October–November) create stunning landscapes, ideal for hiking and photography.

By aligning your goals with the climate, you can maximize enjoyment while avoiding common travel pitfalls.

What to Pack for Hai Phong

Essentials for Each Season

Packing correctly is just as important as picking the right travel dates. Depending on Hai Phong weather, here’s what you’ll need:

• Summer: Lightweight, breathable clothing; sunscreen; sunglasses; wide-brimmed hat; and an umbrella for sudden showers.
• Winter: Warm layers, including sweaters, jackets, scarves, and closed shoes. While snow is unheard of, the damp cold can feel penetrating.
• Rainy season: A waterproof jacket, quick-dry clothing, and insect repellent are essential. Carrying a compact umbrella can also be handy.

Travel Gear for Coastal and Island Trips

Many travelers head to Hai Phong as a gateway to Cat Ba Island or Do Son Beach. For such trips, consider bringing:

• Swimwear and beach sandals
• Dry bags to protect electronics from water splashes
• Snorkeling gear, if you plan to explore Cat Ba’s waters
• A reusable water bottle to stay hydrated
• A power bank for long day trips without charging stations
• A reliable camera to capture the natural beauty of Lan Ha Bay
