Bangkok and Chiang Mai offer the better balance

Chiang Mai is the strongest choice if you want warmth with fewer interruptions from rain. Its 28°C days suit spending time outdoors, while nights at 19°C offer more relief from the heat than the coastal destinations. With 4 rainy days, it is also the driest option here. Bangkok has 6 rainy days, so it is another sensible base if dry weather matters more than being beside the sea. The trade-off is heat: daytime temperatures reach 31°C, making it the hottest destination listed. Plan less strenuous outings around midday and keep water handy. Bangkok's 23°C nights stay warm, whereas a light layer may feel useful in Chiang Mai after dark.

The coast is warm, but rain is the compromise

For a coastal stay, November suits travellers who can accept wet weather rather than those counting on uninterrupted sunshine. Phuket and Koh Samui each have 21 rainy days; Khao Lak and Krabi each have 23. That makes all these coastal options substantially wetter than Bangkok or Chiang Mai. Daytime temperatures of 28°C to 29°C still make lightweight clothing sensible, but pack rain protection and leave outdoor plans flexible. The country sunshine average is 3.7 hours, so warmth should not be mistaken for reliably sunny skies. Phuket and Koh Samui have slightly fewer rainy days than Khao Lak and Krabi, but the difference is not enough to make either a dependable dry-weather choice.
