Overview of Ayutthaya’s Climate
Ayutthaya sits in a tropical savanna climate zone. The weather stays warm to hot year-round.
Rainfall changes a lot by season, shaping when you’ll find drier air or heavy showers.
Tropical Savanna Climate Characteristics
Ayutthaya follows a tropical savanna pattern. You’ll notice a distinct dry period and a wet season.
Temperatures run high all year, with average daytime highs from 32°C to 38°C. Nights are usually warm too, rarely dipping below 20°C.
Humidity often climbs above 70%, especially during the rainy months. The dry season, though, brings comfortable conditions and clearer skies.
Rainfall doesn’t spread out evenly. For example:

Snow never falls here, and frost just isn’t a thing. You can count on sunshine, even when it’s cloudier, so outdoor activities are possible almost all the time.
Seasonal Patterns in Ayutthaya

The cool season, from November to February, brings mild temperatures and almost no rain. Walking tours and temple visits feel easiest now.

Travel Tips and Prices in Ayutthaya’s Winter
Winter in Ayutthaya means cooler air, lighter humidity, and just better conditions for wandering the city’s temples and markets.
Costs, crowds, and what you can do will change depending on when you visit, so a little planning goes a long way toward balancing comfort, budget, and experience.
Best Time to Visit
Ayutthaya’s winter stretches from November to February. Daytime temperatures usually hit between 18°C and 32°C (64°F–89°F). It barely rains, so this is easily the driest time of year.
If you’re after the best weather, go in December or January. Skies stay mostly clear, and the evenings cool off a little, which doesn’t happen often in central Thailand. Walking or biking around the ruins suddenly feels a lot more doable.
You’ll also catch a few festivals during winter. Loy Krathong in November stands out, with floating lanterns and riverside ceremonies lighting up the city. If you want to be part of it, book your hotel early—rooms get snatched up fast.
Tourist Crowds and Activities
The great weather draws in a lot of visitors, so winter is definitely peak tourist season in Ayutthaya. You’ll notice bigger crowds at famous spots like Wat Mahathat and Wat Chaiwatthanaram, especially in the mornings or late afternoons.
Even with more people around, winter is still the top time for outdoor activities. You can grab a bicycle to explore the historical park, hop on a boat along the Chao Phraya River, or wander through night markets without worrying about sudden downpours.
If you want a bit more peace, try visiting temples early or head out to less popular sites beyond the main island. You’ll dodge the crowds and still get that comfortable winter weather.
Seasonal Prices and Accommodation
Winter brings a spike in demand, so hotels and guesthouses bump up their prices compared to the rainy season. You might find a budget room for about 500–800 THB per night. Mid-range hotels usually sit somewhere between 1,200–2,500 THB.
If you’re eyeing those riverside resorts, expect to pay over 3,500 THB.
Food prices and local transport? They pretty much stay the same all year. Street meals typically run 40–70 THB.
Tuk-tuk rides around town cost anywhere from 60–150 THB, depending on how far you’re going.
If you want to save a bit, try booking your room ahead of time or look just outside the main tourist zones. Odds are, you’ll get better rates and still be close enough to all the historic spots.
