January is very-high for Pattaya.
January is Pattaya at its best — the heart of the cool, dry season, with sunny days around 32°C/24°C, low humidity for the tropics, and very little rain (about 15mm). The seas are at their calmest, so Koh Larn ferries run reliably and the water is clearest.
This is peak tourist season. It's the ideal month for island days, the Sanctuary of Truth, Nong Nooch Garden, and the beaches, with comfortable evenings for night markets and sunset dining on Pratamnak Hill. Mornings and late afternoons are perfect for outdoor sightseeing; the midday sun is still strong.

Pattaya in January — Full Picture
January is Pattaya at its best — the heart of the cool, dry season, with sunny days around 32°C/24°C, low humidity for the tropics, and very little rain (about 15mm). The seas are at their calmest, so Koh Larn ferries run reliably and the water is clearest.
This is peak tourist season. It's the ideal month for island days, the Sanctuary of Truth, Nong Nooch Garden, and the beaches, with comfortable evenings for night markets and sunset dining on Pratamnak Hill. Mornings and late afternoons are perfect for outdoor sightseeing; the midday sun is still strong.
The trade-off is crowds and price. New Year carryover keeps the first part of the month busy, and the best beachfront resorts run high — book ahead. UV is extreme year-round here, so high-SPF, reef-safe sunscreen, a hat, and water are essentials even on the cooler-feeling days.
What to Wear & What to Pack
Peak cool-dry season — warm and sunny at 32°C/24°C with low rain and pleasant evenings. Light, breathable clothing, swimwear, a hat, and sunglasses. A light layer for air-conditioned malls. UV is extreme — high-SPF sunscreen essential.
