Best time to visit Thailand in 2024: when to go?

Thailand is a popular travel destination that offers something for everyone – from breathtaking beaches and tropical islands to stunning temples and vibrant cities. With its warm climate and variety of attractions, deciding when to visit this amazing country can be tricky. Here’s a guide on the best time to visit Thailand in 2024.

When is the Best Month to Fly to Thailand?

The best time to visit Thailand is generally considered to be between November and March. This is Thailand’s dry season when rains are less frequent, temperatures are a bit cooler, and humidity is lower.

Some of the best months to visit are:

  • November – One of the most popular months. The rainy season is ending so the weather is improving. Temperatures are still high at around 86°F. Deeply significant holidays like Loy Krathong festival.
  • December – Cooler and comfortable temperatures averaging 82°F. Great beach weather on both coasts. Busy around Christmas and New Year’s.
  • January – Similar to December. Cool and dry season. Great for beach destinations like Phuket. Chinese New Year celebrations toward the end of the month.
  • February – Hot and dry. Temperatures begin rising to 86°F. High season remains in full swing. Fun festivals like Makha Bucha Day.
  • March – Hottest month of the dry season with temps up to 95°F. Songkran water festival takes place bringing big crowds.

The peak tourism season runs November through March when the weather is ideal, and you’ll find busy crowds and higher prices. For cheaper deals and fewer people, visit during the hotter months of April and May.

Cheapest Months in Thailand

If you’re looking for the cheapest time to visit Thailand, aim for the hot summer months of April, May, or September.

  • April – Marks the beginning of the hot season with temperatures around 90°F. Humidity rises too. Songkran celebrations extend into April. Smaller crowds and lower rates.
  • May – One of the hottest months with highs around 95°F. Lower costs compared to the high season months. Great for nature lovers.
  • September – Still hot and humid but the rains have subsided. Good deals on hotels and flights. Ideal for a budget-friendly trip.

Keep in mind the weather will be sweltering during these cheap months. Temperatures can reach 100°F and humidity is high. If you can stand the heat, you’ll be rewarded with smaller crowds and big travel savings.

When is the Rainy Season in Thailand?

Thailand’s rainy season generally runs from June through October. The southwest monsoon brings heavy rainfall especially along the south’s east coast and islands like Samui and Phuket.

The worst of the rains typically happen in September and October. However “rainy season” doesn’t mean non-stop downpours. You’ll still get nice beach days mixed with storms. Having some wet weather gear and travel insurance can allow you to take advantage of low season deals.

Here’s an overview of rainy season by area:

  • Phuket – Wettest from September to October.
  • Bangkok – Heaviest rainfall from August to October.
  • Chiang Mai – Rain picks up in May and continues through October.
  • Koh Samui – Most rain late September through early December.

If planning a trip during rainy season, build flexibility into your itinerary in case storms disrupt travel plans. Focus on indoor activities or plan excursions for mornings before the rains typically start. With the right precautions, you can still enjoy Thailand even during wet season.

If your schedule is flexible, visit during shoulder seasons like May or September to save. However, for ideal weather and experiencing festive events, late fall to early spring is worth the higher rates for many travelers.

FAQs: Worst Month to Visit Thailand 

When is the worst time of year to visit Thailand?

  • The worst time is typically September and October which are the peak months of rainy season. This brings very heavy rainfall, potential flooding, strong winds for islands, and more mosquitoes.

When is the worst time to visit Chiang Mai?

  • March to May is challenging in Chiang Mai as it’s extremely hot before the rainy season starts. September-October also brings very heavy rainfall.

Should I avoid Thailand in October?

  • October still sees heavy rain, especially in southern Thailand and islands like Phuket or Koh Samui. However, the rains often lessen in the afternoons so you can still enjoy outdoor time. With an umbrella and flexible plans, you can manage October travel.

What month is typhoon season in Thailand?

How bad is monsoon season in Phuket?

  • Phuket gets pounded with rain from September to early December during monsoon season. Over 12 inches of rain falls per month making flooding likely. Resorts often close and boat travel is limited so Phuket struggles during the rainy months.

Is it worth going to Thailand in September?

  • September is one of the wettest months in Thailand. However, with weather precautions and flexibility, you can still have a great trip as crowds are light and prices drop between high seasons. Monitor forecasts and the weather shouldn’t deter you from visiting in September.

Final Thoughts: Worst Time to Travel to Thailand

While Thailand offers warm temps and sights year-round, September and October are often considered the worst time to visit due to very heavy rainfall. The summer months can also be unpleasantly hot. For ideal weather, low humidity, and celebrations like Songkran, aim for November through February.

However, the low season has benefits too like smaller crowds and lower prices. By packing for heat or rain, the weather doesn’t have to ruin a summer or monsoon trip to Thailand. With the right mindset, you can find the “best” time to visit this magical country.
