Is December Right for You?
Weigh the advantages and considerations before booking
Advantages
- + December swaps the monsoon's hammering rain for flawless mornings that begin at 24°C (75°F) and ease up to 31°C (88°F) by noon, weather so flawless that sea kayakers dawdle in Phang Nga Bay's limestone lagoons instead of sprinting back to shore.
- + Hotel prices along Krabi's shoreline tumble 30-40% from November's peak rates, so the bungalows at Railay East, usually snapped up months ahead, suddenly open up with just 7-10 days notice.
- + The Andaman Sea slips into its calmest mood of the year, giving glass-flat conditions good for speedboat hops to Phi Phi Leh and bamboo long-tail runs through the Hong Islands' tucked-away lagoons that September's swells would make impossible.
- + Local long-tail captains, grounded by weather since August, are eager for work, which means more flexible departure times and a readiness to tailor island routes that high season's fixed timetables would never allow.
Considerations
- − The UV index rockets to 8 by 10 AM, fierce enough to scorch through cloud cover, so beach days demand disciplined reapplication of SPF 50+ and the shade-hunting tactics locals have mastered over decades.
- − December rubs shoulders with Christmas vacationers, so while hotel rates fall, the beaches at Ao Nang and Klong Muang grow noticeably busier from December 20th onward, when European holiday makers arrive en masse.
- − Some of Krabi's most dramatic offshore spots, including the Emerald Pool and Tiger Cave Temple's 1,237-step climb, can feel oppressive at midday when humidity hovers around 70% and there's no breeze at elevation.

December Events & Festivals
What's happening during your visit
Early December
Krabi Boek Fa Andaman Sea Festival
Across three December days, Krabi kicks off tourist season with long-tail boats sprinting past one another, seafood piled high on Ao Nang's main beach, and long-drum rhythms bouncing off limestone walls. Fishermen race boats trimmed with ribbons while vendors sear the morning catch over open flames, lemongrass-marinated squid smoke drifts across the sand as dancers spin through the Nora, a southern Thai ritual born from ancient seafaring life.
Early December
King's Cup Regatta
Asia's flagship yachting event turns the stretch between Krabi and Phuket into a salt-spray theatre: 200+ hulls tear past the Phi Phi Islands while spectators watch from long-tails parked along the course. Each night the regatta village at Nopparat Thara Beach throws parties where sailors swap stories over Chang beer and the metallic clatter of rigging against masts becomes December's signature soundtrack.

Insider knowledge and common pitfalls to avoid
Insider Knowledge
At local seafood spots like 40-year-old Wang Sai in Ao Nang, English menus are absent, point to the ice display and ask for 'pla samli rot' (deep fried snapper), a dish that never shows on tourist menus.
The 7-Eleven at Nopparat Thara Beach hides Krabi's widest range of local craft beer from microbreweries, look past the Chang towers in the back cooler.
Songthaew drivers quote 150 baht for Ao Nang to Krabi town. Walk 100 meters toward the main road and flag a shared ride for 20 baht, locals pull this move every day.
The Emerald Pool's quiet entrance sits 500 meters beyond the official ticket booth; a dirt track leads to a smaller, equally dazzling pool tour groups never reach.
Avoid These Mistakes
Avoid booking island tours through hotel desks, they tack on 30%. Walk to Ao Nang's pier and haggle directly with boat captains for sharper rates.
Don't wear flip-flops on the Tiger Cave Temple climb, 1,237 granite steps slick with morning dew demand proper trainers, as every local already knows.
Don't assume December is rain-free, afternoon showers strike 60% of days between 2-4 PM, drenching beach bags left on long-tail decks.
