January is the middle of Krabi’s dry season: fewer rainy days than December, every island park open and the province in high season. Below are Thai Meteorological Department (TMD) normals for the province’s two stations, TMD’s outlook for January 2027, what is open, how busy it gets and where Chinese New Year falls. Checked on 11 November 2026.
Krabi weather in January: TMD numbers
The Krabi station (48 563) is inland near Krabi Town, about 18 km from Ao Nang, and its record covers 1994-2020. The Ko Lanta station (48 566) covers 1991-2020. A rainy day means 0.1 mm or more.
| January | Krabi (48 563) | Koh Lanta (48 566) |
|---|---|---|
| Average high | 32.6 °C | 32.6 °C |
| Average low | 21.5 °C | 24.1 °C |
| Rainfall | 96.8 mm | 31.0 mm |
| Rainy days (0.1 mm or more) | 7.7 | 3.9 |
| Days with thunderstorms | 1.4 | 0.1 |
| Wettest single day on record | 125.1 mm | 98.0 mm |
| Humidity | 75% | 76% |
| Prevailing wind | northeast | northeast |
January is the month when the two stations differ most: the mainland station gets three times Koh Lanta’s rain. Days are a degree hotter than in December and the air is drier, 75% humidity against 80%. All twelve months are on Krabi weather by month and Koh Lanta weather by month.
Is January the driest month in Krabi?
No. At the Krabi station the driest month is February. January’s total is slightly above December’s, but it falls on fewer days:
| Month | Krabi rain, mm | Krabi rainy days | Koh Lanta rain, mm | Koh Lanta rainy days |
|---|---|---|---|---|
| December | 90.3 | 11.1 | 64.6 | 9.6 |
| January | 96.8 | 7.7 | 31.0 | 3.9 |
| February | 35.9 | 4.3 | 24.1 | 2.2 |
| March | 108.4 | 8.3 | 69.0 | 5.6 |
So January has more fully dry days than December, and the rain that does come can be heavy: the wettest January day in the 1994-2020 record brought 125.1 mm, more than the monthly average. What this means for planning:
- In Ao Nang and on Railay expect a shower on about one day in four, going by the nearest station
- For the fewest wet days, stay on Koh Lanta or come in February
- TMD counts any day with 0.1 mm as rainy, so a rainy day is rarely a lost day
TMD outlook for January 2027
From TMD’s cool season outlook issued on 9 October 2026 (TMD’s seasonal page showed no update on 11 November):
- Andaman coast in January: minimum temperatures of 24-26 °C and rain over 10-20% of the area
- Andaman Sea waves of 1-2 m through the cool season
- For the south as a whole TMD expects the heavy rain of mid-October to early January, mostly on the Gulf side, to ease after that as the northeast monsoon weakens
- TMD expects El Niño to strengthen in late 2026 and continue into early 2027, which may keep temperatures above normal
It is a long-range outlook. Before a boat day, check the TMD 7-day forecast under Southern (West Coast).
Sea and beaches in January
Both stations record the wind from the northeast in January, at a mean of 3.8 knots, so it blows off the land at Ao Nang, West Railay and the west coast beaches of Koh Lanta. This is our reading of TMD wind data, not a wave measurement, and TMD normals have no sea temperature or wave height.
- Longtails leave from Ao Nang beach and speedboats from Nopparat Thara pier: Ao Nang: piers and boats
- The sun is strong at 32-33 °C, so take boat trips and climbs in the morning
- Where to stay by type of holiday: Ao Nang, Railay and Koh Lanta
What’s open in January
| Place | Status in January 2027 | Foreign adult fee | Source |
|---|---|---|---|
| Railay and Phra Nang beach | open, no annual closure | 200 baht at Phra Nang, which is inside the park | DNP |
| Poda, Chicken and Tub islands | open, snorkelling and diving off the west side of Chicken Island closed since 16 May 2026 | 200 baht | DNP |
| Hong Islands | open, no annual closure | 300 baht | DNP |
| Phi Phi and Maya Bay | open, Maya Bay closes only from 1 August to 30 September | 400 baht | DNP |
| Ko Rok and Ko Haa | in season: 16 November-15 May on the DNP park page | 400 baht | DNP |
| Emerald Pool | open all year, on land | 400 baht, a wildlife sanctuary, not a DNP park | our sight page |
| Tiger Cave Temple | open all year, on land | free | our sight page |
Closure periods are from the DNP closure table for 2026 (data as of 7 January 2026, read on 11 November). The 2027 table is not published yet, so we use the annual periods from the 2026 one. Fees are from the DNP table for individuals (2 June 2023), and children pay half. Ko Yung in the Phi Phi group is listed as closed indefinitely. For Ko Rok the DNP status list still carries an older closure entry, so confirm your date with the operator or the park.
TAT notes that six marine national parks, including Phi Phi and Ko Lanta, have used electronic tickets since October 2025: buy yours in advance and have your passport ready.
Which trips suit January
With fewer wet days, January is the month for the longer days at sea:
- Koh Lanta with Ko Rok. Two or three nights on the driest island of the province and a snorkelling day in the national park: Koh Lanta, boats and minivans on Krabi to Koh Lanta
- Phi Phi. By speedboat from Ao Nang or by ferry from Krabi Town, times and fares on Krabi and Ao Nang to Phi Phi
- Hong Islands. A lagoon, beaches and a viewpoint in a 6-9 hour day: Hong Islands from Ao Nang
- Railay and Phra Nang. About 15 minutes by longtail from Ao Nang, half a day without a tour
- Mainland. The Emerald Pool and the Tiger Cave Temple, with the temple stairs best climbed in the morning
All trips with duration and fees are on Krabi excursions.
How busy Krabi is in January
The Ministry of Tourism and Sports (MOTS) counts hotel occupancy for Krabi province as a whole, which includes Ao Nang, Railay, Koh Lanta and Phi Phi. January 2025, the latest January in the MOTS file, was at 77.07%, up from 65.03% a year earlier. The province had 560,300 visitors, 361,452 of them foreign.
| Month | Krabi hotel occupancy | Phuket hotel occupancy |
|---|---|---|
| December 2025 | 80.91% | 84.10% |
| January 2025 | 77.07% | 86.41% |
| February 2025 | 73.64% | 82.08% |
By this measure January in Krabi is busy, but less full than December and well below Phuket. What to book ahead:
- Ferries and island stays. TAT’s advice for the Andaman coast this season is to book ferries and island accommodation early for December and January
- The first days of the month. New Year’s Day is a bank holiday on Friday 1 January, so the holiday break runs to Sunday 3 January
- Flights from Bangkok. On 31 October the lowest Thai AirAsia fare on the AirAsia MOVE calendar was 1,477 baht for 12 January, against a peak of about 3,500-3,950 baht in late December: Bangkok to Krabi
We do not publish hotel rates until we collect our own dated measurements. From Phuket see Phuket to Krabi, and for the last leg Krabi Airport to Ao Nang and Railay.
New Year and Chinese New Year 2027
| Event | Date | Source |
|---|---|---|
| New Year’s Day | Friday 1 January, bank holiday | Bank of Thailand |
| Chinese New Year | Saturday 6 February, not in January | Hong Kong SAR Government |
The Bank of Thailand’s 2027 list, Notification No. 37/2569, has no other holiday in January. Lunar New Year’s Day 2027 is 6 February, so a January trip misses it, and a trip that runs into the first week of February meets it. As of 11 November TAT had not published January 2027 events for Krabi, and we list no events we could not confirm.
Krabi, Phuket or Koh Samui in January
TMD normals for January, 1991-2020 (Krabi 1994-2020):
| Place and station | Average high | Average low | Rain | Rainy days |
|---|---|---|---|---|
| Krabi (48 563) | 32.6 °C | 21.5 °C | 96.8 mm | 7.7 |
| Koh Lanta (48 566) | 32.6 °C | 24.1 °C | 31.0 mm | 3.9 |
| Phuket Town (48 564) | 33.0 °C | 25.0 °C | 49.9 mm | 5.6 |
| Koh Samui (48 550) | 29.0 °C | 24.2 °C | 126.8 mm | 11.1 |
Phuket Town gets about half of Krabi’s rain in January and Koh Lanta a third. Koh Samui is wetter than the Andaman side with 126.8 mm, though far drier than in December. Beyond the weather, the two Andaman bases are compared on Phuket or Krabi. The same month elsewhere: Phuket in January and Koh Samui weather by month.
Should you go to Krabi in January?
Go if:
- you want hot, mostly dry days: 32.6 °C and rain on about one day in four
- you want every island trip available, including Ko Rok from Koh Lanta
- you can book boats and island stays ahead
Consider another month or base if:
- you want the driest weeks: February brings 35.9 mm in Krabi and 24.1 mm on Koh Lanta
- you want the least rain in January itself: stay on Koh Lanta, not on the mainland
- you want Christmas and New Year by the sea: that is Krabi in December
The province guide is the Krabi travel guide, the whole country is in Thailand in January, and closures for the islands shared with Phuket are on Phuket islands open by month.
