Is December Right for You?
Weigh the advantages and considerations before booking
Advantages
- + December brings Ayutthaya its driest month of the year. Essentially zero measurable rainfall falls. The floodwaters that swallow low-lying temple ruins through September and October have vanished entirely. Laterite and brick foundations of the Historical Park lie fully exposed and walkable. You can cycle an entire day between Wat Mahathat, Wat Ratchaburana, and the outer ruins near Wat Chai Watthanaram. Never once check the sky.
- + Mornings drop to 22°C (72°F). For central Thailand's river plain, this feels almost cool. The hour after sunrise, roughly 6:15 to 7:15 AM, offers the single best window for exploring ruins. Avoid the flattening midday glare. Sandstone and stucco catch low-angle light that reveals surface texture lost by noon. Resident monitor lizards stay sluggish on the cool grass. Walk past without bolting.
- + December sits inside Thailand's high season. Ayutthaya absorbs pressure differently than beach destinations. Most international visitors treat it as a day trip from Bangkok. The Historical Park empties dramatically after the last afternoon minivans depart around 4 PM. Overnight in Ayutthaya. Evening and early morning hours become yours almost alone. Chiang Mai and Phuket stopped offering this a decade ago.
- + The Chao Phraya and Pa Sak rivers settle to post-monsoon levels by December. Longtail boat circuits of the island become reliable and scenic. Water runs clearer than during monsoon months. Riverbank temples photograph cleanly. Wat Phanan Choeng holds a 19-metre (62 ft) seated Buddha visible from the water. No muddy brown churn of wet season clutters the view.
Considerations
- − December marks high season across Thailand. Ayutthaya stays calmer than southern islands. Accommodation in the small stock of guesthouses and boutique properties fills earlier than travelers expect. The town holds fewer than 40 places Western visitors would consider comfortable. Better ones book out two to three weeks ahead for December weekends. Weekday flexibility works easiest.
- − Humidity sits at steady 70% even through dry season. Midday temperatures of 31°C (88°F) feel heavier than numbers suggest. Between 11 AM and 2 PM ruins offer almost no shade. Brick and laterite radiate stored heat underfoot. Day-trippers from Bangkok arrive in this window. You get worst of crowd and worst of sun simultaneously.
- − Ayutthaya's food and nightlife scene runs thin compared to Bangkok, Chiang Mai, or even Kanchanaburi. After dark the old island goes quiet. Dining options outside the night market near Bang Ian Road narrow to a handful of shophouse restaurants and riverside terrace spots along U Thong Road. This town sleeps early. December changes nothing.
Best Activities in December
Top things to do during your visit
December air in Ayutthaya is dry, almost crisp, a blunt break from the swampy blanket that smothers the city most months. Mornings open at 72°F, rain is a rumor, and the ruins invite you to walk or pedal for hours. Light bounces off laterite and brick, shadows stretch like accusations, and dust lifts from the parched earth with every footfall. Vendors know the drill: grills hiss, iced coffee clinks, charcoal smoke curls around temple gates. No festivals clutter the calendar, so the tempo stays steady, a rare window when neither monsoon nor April furnace derails your plans. That reliability makes December the easiest month for the 80-km dash from Bangkok, whether you follow the Chao Phraya or the highway under hard blue skies. When you list things to do in Ayutthaya, December's climate tops the page. Data says it is the coolest, driest month, mirroring January almost exactly. You can plot a full day without packing a poncho. Cyclists drift between Wat Mahathat and Wat Phra Si Sanphet, river breeze on their faces, bells from working monasteries drifting across the scrub. Google "Ayutthaya weather" and you will land on this sweet spot every time.
From Bangkok: Ayutthaya Temples Guided Tour with Lunch
culturalA guided run from Bangkok hands you the keys to the ruined capital. The guide deciphers stone stories, points out the Buddha head locked in bodhi roots at Wat Mahathat, sketches palace floor plans and royal rites. Lunch is included. Expect sharp tom yum or a tangle of pad Thai, fuel before you move on to the stepped pagodas of Wat Yai Chai Mongkhon.
The tour turns quiet rubble into a living chapter of Siamese history.
Insider tip: Beg for the earliest departure the operator allows. You will beat both the midday heat and the coach crowds.
From Bangkok: Ayutthaya & Ayothaya Floating Market Day Trip
day_tripThis outing pairs the park's solemn stones with the theatrical chaos of Ayothaya Floating Market. Boats bob beneath you, vendors ladle boat noodles, mango sticky rice steams, the reek of pla ra slaps your nose, music crackles overhead. One minute you are among ghosts, the next you are haggling over lunch.
It nails the region's split personality: ancient gravity versus canal life that refuses to quit.
Insider tip: Circle the entire market before you buy. Prices and specials shift from stall to stall.
Bangkok: Ayutthaya, Railway & Floating Markets Full-Day Tour
day_tripThis full-day sampler stitches three Thai classics: Ayutthaya ruins, a train-thronged railway market, and a color-splashed floating market. Feel the carriages thunder past your elbow, see chilies and rambutan piled high, snag grilled prawns from a canoe. Logistics are handled. You just turn up the volume on your senses.
It layers spiritual stone, rail-side nostalgia, and waterborne commerce into one easy hit.
Insider tip: Wear closed-toe shoes you do not love. Dust at the ruins, splash at the piers.

December Events & Festivals
What's happening during your visit
December 5
King Bhumibol Memorial Day (Wan Pho)
December 5th is a national holiday. It honours the late King Bhumibol Adulyadej. Ayutthaya marks it with merit-making ceremonies at major temples. Wat Phra Si Sanphet and Wat Mahathat draw particular attention. Locals wear yellow shirts. They gather at temple grounds from early morning. Some government offices close. Banks too. Smaller shops as well. The temples shift character. More Thai families. Fewer tourists. Incense and marigold offerings thicken the air. Scent and colour density exceed ordinary visiting days. Alcohol sales face restriction on this date.
December 10
Constitution Day
December 10th marks Thailand's first constitution as a public holiday. Ayutthaya holds no major events. But government offices, post offices, and some businesses close. The Historical Park stays open. Crowds thin as Thai families travel elsewhere. Plan banking around this.
Late December
New Year Countdown Celebrations
Late December brings modest countdowns along the riverside and at larger temples. Wat Phra Si Sanphet and Bueng Phra Ram host small evening festivals with food stalls and local performances. Nothing rivals Bangkok's Centralworld spectacle. That is the point. Temple bells ring at midnight on December 31st. Local families gather. The cool river air makes midnight pleasant, not oppressive.

Insider knowledge and common pitfalls to avoid
Insider Knowledge
The train from Bangkok's Hua Lamphong or newer Bang Sue Grand Station reaches Ayutthaya in ninety minutes. It drops you across the river from the island. The ferry takes five minutes. It lands steps from guesthouses on Naresuan Road. Most day-trippers arrive by minivan directly to the Historical Park. They miss this side entirely. Here sits the cheapest bicycle rentals and better local lunch spots.
The Historical Park's combination ticket covers six major ruin sites. It saves meaningfully over individual fees. Buy at your first site. The ticket excludes Wat Yai Chai Mongkhon, Wat Phanan Choeng, and Wat Na Phra Men. These charge separately. They sit outside the main boundary. Budget independently if your route includes them.
Boat noodles belong to Ayutthaya. They arrive in tiny bowls meant for stacking. Locals order ten to fifteen bowls. Empty bowl counts are half the fun. The boat noodle strip near the old market on the island's east side draws Thai visitors. English guidebooks ignore it. The broth is dark, rich with dried spices and pork blood. It tastes like nothing served under the same name in Bangkok.
December weekends bring domestic Thai tourists. Weekdays do not. Shift your Historical Park visit to Monday through Thursday if possible. Crowd density at Wat Mahathat changes dramatically. The famous Buddha head entwined in tree roots sits here. On a December Tuesday at 7 AM, you photograph it alone. On Saturday at 10 AM, you queue.
Avoid These Mistakes
Do not treat Ayutthaya as a half-day trip from Bangkok. Do not try seeing everything between 10 AM and 3 PM. The sprawl exceeds most visitors' expectations. Midday heat slows you. Best light and emptiest grounds come at dawn and late afternoon. Overnight stays unlock two golden windows day-trippers miss structurally.
Do not skip Wat Chai Watthanaram. It sits across the river from the main island cluster. This is arguably Ayutthaya's most photogenic ruin complex. Its Khmer-influenced prang silhouetted against sunset graces travel magazine covers. Ten minutes by bicycle from the western bridge. Reachable by longtail boat. December's clear skies make sunset views worth rearranging your afternoon.
Wearing shorts and sleeveless tops to the ruins and being turned away from the active temples. The Historical Park ruins themselves are largely open-air archaeological sites with no dress code, which gives visitors the false impression that the entire city is the same. Wat Phanan Choeng and Wat Yai Chai Mongkhon are functioning monasteries and enforce coverage strictly. Pack a cover-up. This avoids the awkward choice between skipping them and buying an overpriced wrap from a vendor at the gate.
