What is spring like in Thailand?

Thailand, like many Southeast Asian countries, does not have spring in the traditional four-season sense, but the March to May period is often considered the transition from the cooler dry season into warmer months.

You can generally expect;

  • Warm to hot temperatures

  • Mostly dry conditions, especially earlier in the season. Rain will pick up towards late spring.

  • Clear skies and beautiful days.

  • The cities will be very lively, as will the beach and popular tourist spots.

Across spring, April is typically the hottest month, particularly in central and northern Thailand.

Best places to visit in Thailand during spring

Bangkok

Spring is a great time for a city-focused trip to Bangkok, especially if you enjoy food, culture, and markets.

Bangkok highlights include;

  • Temples and historic sites

  • Street food and dining scenes

  • River cruises and neighbourhood exploring

Mobile data is extremely useful here for transport apps, navigation, and finding places to eat.

Phuket and Krabi

Thailand’s southern beaches are popular in spring, especially before the wetter conditions arrive shortly after.

Down here, you will find clear water and calm seas across the many popular tourist attractions. If you are seeking a coastal holiday, in beach resorts or in coastal towns, with island hopping and boat tours, then this is where you want to go. Spring offers great weather, but be prepared for crowds.

Chiang Mai

In northern Thailand, spring brings warm days and cultural experiences.

Chiang Mai is best known for its ancient temples, mountain scenery, markets and local foods. If you are looking for slower-paced travel than Bangkok, Chiang Mai is for you.

It is also a great base for further exploring Northern Thailand’s mountains and national parks. You can easily get to Doi Inthanon, Thailand’s tallest mountain and national park.

Songkran: Thailand’s biggest spring festival

One of the biggest reasons travellers visit Thailand in spring is Songkran, the Thai New Year, held in mid-April. If you are looking to go this year (2026), it is on April 13-15. It’s pretty much like a several-day water fight in the streets. People splash water on each other to wash away the old year’s misfortunes. Additionally, there are many parades and celebrations, street events, and lots of great food.

Be prepared for large crowds, busy transport and fully booked accommodation in popular areas. If you intend to visit this year, I suggest you start planning now.

Spring travel tips for Thailand

If you are familiar with travelling through Southeast Asia, you’ll already know what to expect. But for those first-timers, these few tips will make spring travel much more comfortable.

  • Pack lightweight clothing and sun protection

  • Plan sightseeing early in the day to avoid peak heat (and crowds)

  • Stay hydrated, especially in April. Get bottled water whenever you have the opportunity to.

  • Book accommodation early if you plan on visiting Songrak, or even the southern areas like Phuket and Krabi.

  • Have mobile data ready for transport, bookings, and navigation.

Staying connected while travelling in Thailand

Thailand is highly connected, and many services rely on mobile apps. You can expect to need mobile data for;

  • Ride-hailing and taxis

  • Food delivery

  • Hotel bookings

  • Navigation and maps

  • Translation and communication apps

While Wi-Fi is widely available, especially in the cities, it is not always reliable when you are moving around, visiting islands, or attending festivals.

Using an eSIM in Thailand

I recommend getting an eSIM for your travels through Thailand. It offers a simple way to stay connected without swapping physical SIM cards or relying on expensive international roaming.

With data providers like Pocket Roam, travellers can:

  • Install a Thailand eSIM before departure

  • Connect to local networks as soon as they land

  • Choose between fixed data or unlimited data plans to suit your needs

Using an eSIM will save you a lot of stress when travelling in spring, where the days are long and busy, and plans often change on the go.

Fixed data or unlimited data for Thailand?

Both options work well, depending on how you travel.

Fixed data plans are suitable if you:

  • Use maps and occasional messaging

  • Spend time on hotel or cafe Wi-Fi

  • Want a predictable, lower-cost option

Unlimited data plans are better if you:

  • Are out exploring all day

  • Rely heavily on navigation and apps

  • Want to frequently upload and share photos and videos

  • Want one less thing to worry about (tracking how much data you have left)

Many travellers to Thailand in spring choose unlimited data plans for the convenience during hot, busy days.

Final thoughts

Spring is an ideal time to visit Thailand, combining warm weather, cultural festivals, and excellent beach conditions. Despite the higher temperatures, good planning and flexibility make spring a very rewarding season to explore the country.

Having reliable mobile data ready before you arrive helps remove stress, especially during busy periods like Songkran. With the right preparation, spring in Thailand can be both vibrant and unforgettable.
