Thailand weather in November
November is the moment Thailand trades monsoon drizzle for blue-sky “cool season” comfort. Daytime averages slip to 26 – 30 °C / 79 – 86 °F, humidity falls sharply and festival lights glow from Bangkok to Chiang Mai. Below is an at-a-glance climate map, beach advice and practical planning tips—followed by a soft nudge on how Tonkin Voyage Travel can weave November’s best weather into a seamless Indochina itinerary.
1 | Regional Weather Snapshot (°C / mm)
| Region | Day / Night | Rain (mm) | Travel note |
|---|---|---|---|
| Bangkok & Central Plains | 29 / 23 | ≤ 50 | Brief showers; rivers sparkle after Loi Krathong (5 Nov 2025). |
| Northern Highlands (Chiang Mai, Pai) | 28 / 18 | ≤ 30 | Trekking season; dawns at Doi Inthanon dip to 15 °C—pack a light fleece. |
| Isan & Mekong River | 30 / 21 | ≤ 20 | Sun-drenched temple ruins (Phimai) and illuminated boat races in Nakhon Phanom. |
| Andaman Coast (Phuket, Krabi) | 31 / 24 | ≤ 80 | Dry-season kick-off; long-tail boats resume to Phi Phi & Similan dive sites. |
| Eastern Gulf (Koh Chang, Koh Kood) | 30 / 24 | ≤ 90 | Calm seas + flowing waterfalls—ideal quiet-beach alternative to Phuket. |
| Southern Gulf (Koh Samui, Phangan, Tao) | 29 / 25 | 250 – 300 | Northeast monsoon peaks: heavy downpours & choppy ferries—wait until mid-Dec. |
2 | Why November Is a Sweet-Spot Month
- Comfort + Sight-see temple complexes all day without the April sauna.
- Festivals: Twin light spectacles—Loi Krathong river floats country-wide & Yi Peng sky-lantern release in Chiang Mai (4–6 Nov 2025).
- Value window: Airfares and hotels rise after 20 Nov; early-month bookings snag cool weather at shoulder-season rates.
3 | Beach Picks (and Avoids)
Go west & east: Phuket, Khao Lak, Krabi and the quieter duo of Koh Chang / Koh Kood deliver postcard water and almost-dry skies.
Press pause on Samui: The Gulf islands are still in full wet season—save them for Christmas onward.
4 | Packing Cheat-Sheet
- Light cottons + reef-safe sunscreen.
- Thin sweater for 15 °C dawns up north.
- Compact umbrella—for the odd 15-minute burst even in “dry” zones.

Phuket’s Kata Noi and Khao Lak’s White Sand Beach both offer calm seas, 29 °C water and fully-reopened boat trips to the Similan Islands.

Expect 18 °C valley lows; mountaintops like Doi Inthanon can touch 15 °C—pack a light fleece.
