Weather Details
Temperature
Daytime temperatures in March typically reach the low 30s Celsius (around 90°F), especially in central and northern Thailand. Evenings cool down to the mid-20s Celsius, though it rarely feels cold. We find that early March is often slightly cooler than late March, when the heat really begins to build. It’s warm enough to wear light clothing most of the day, but evenings might call for a light layer.
Rainfall & Humidity
Rainfall remains relatively low, with only a few scattered showers across the month. These are usually brief and don’t disrupt plans much. Humidity starts to rise in March, reaching around 60 to 70 percent. While it can feel sticky at times, it’s manageable, especially if we stay hydrated and plan outdoor activities in the cooler hours.
Sunshine & Daylight
Sunshine hours remain high in March, with around 7 to 8 hours of sunlight daily. Days are long, with sunrise around 6 AM and sunset close to 6:30 PM. This gives plenty of daylight to explore temples, markets, and natural parks. Some cloud cover may appear, but it’s often patchy and doesn’t block the sun for too long.
Sea & Wind
Sea temperatures in coastal areas hover around a warm 29°C (84°F), perfect for swimming and water sports. The wind is mild, providing some relief from the heat but rarely strong enough to cause rough seas. If you’re heading to islands like Phuket or Koh Samui, March offers pleasant beach conditions before the rainy season kicks in.
What to Pack
- Lightweight, breathable clothing such as cotton shirts and shorts
- Sun protection: wide-brim hats, sunglasses, and reef-safe sunscreen
- Comfortable walking shoes or sandals for exploring cities and beaches
- A light rain jacket or compact umbrella for occasional showers
- Swimwear and a cover-up for beach days
- A reusable water bottle to stay hydrated in the warm weather
- If visiting temples, modest clothing to cover shoulders and knees
We often forget that evenings can be cooler, so packing a light long-sleeve shirt or a shawl might come in handy, especially for dining outdoors or on boat trips. Also, insect repellent is a good idea for outdoor excursions.
Events & Festivals in March
March hosts some interesting cultural events that add flavor to your trip. One highlight is the Makha Bucha Day, a Buddhist holiday celebrated with ceremonies and candlelit processions, usually falling in early March. It’s a peaceful and spiritual experience if you want to witness local traditions.
In addition, the Bangkok International Fashion Week sometimes takes place in March, showcasing Thailand’s growing fashion scene. While not a traditional festival, it draws crowds and adds a modern twist to the city vibe.
Keep in mind that some events might make popular locations busier and accommodation prices a bit higher. Booking early can help avoid last-minute hassles.
Is March a Good Time to Visit Thailand?
We think March is a solid choice for travelers looking for warm, mostly dry weather without the crowds of the high season’s peak. The balance of sunshine and occasional rain keeps things fresh, and the sea remains inviting for beach lovers.
That said, the rising heat might be uncomfortable for some, especially those not used to tropical climates. It’s not the best month for hiking in the northern mountains, where temperatures can soar midday. However, cities like Bangkok and Chiang Mai are lively and less crowded than during December or January.
March suits travelers who enjoy hot weather but want to avoid the intense rains of later months. Families, solo travelers, and couples can find plenty to enjoy. We’d say it’s a good time for cultural tours, beach holidays, and urban exploration.
Quick Travel Tips for March
- Plan outdoor activities in the early morning or late afternoon to avoid the midday heat.
- Book accommodations and tours in advance if visiting during local holidays or festivals.
- Stay hydrated and carry water, especially when exploring temples or markets.
- Consider indoor or shaded activities during the hottest parts of the day.
- Use sunscreen liberally and reapply as needed.
- If you’re island-hopping, check boat schedules as weather changes can affect crossings.
