Plan this trip
Each site opens on its own search: choose your dates there. A few open on their home page, where you type the place too.

Travel insurance
Check whether your bank card or home insurance already covers this trip.
If the trip needs a visa, the travel agent or visa centre usually sells the cover it asks for.
Mobile data (eSIM)
Your own plan's EU roaming may already cover this.
Renting a pocket Wi-Fi is the other common way to stay connected.
These are sites people in book with. Each opens in a new tab, on the site's own pages.
The numbers
| Daily high | 32°C |
|---|---|
| Nightly low | 23°C |
| Feels like, afternoon | 37°C |
| Rainy days, 1 mm or more | 11 · 183 mm |
| Humidity | 75% |
| Sunshine | 10.5 h/day |
| Daylight | 13.1 h/day |
| Days over 35°C | 6 |
| Crowds | 80 / 100, higher is quieter |
Ten-year averages for this calendar month. A rainy day is one with at least 1 mm of rain, as a weather station counts it. The model these figures come from drizzles more than a rain gauge, the more so the warmer the month, so its days count from 2 mm, rising to 5 mm in the hottest.
Weather read at the centre (the clock tower), 8 km from the airport (CEI): ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.
How busy it gets

What to pack
- Light, loose clothes: daily highs average 32°C.
- A packable rain jacket for the 11 or so rainy days.
- Plan the middle of the day indoors: 6 days a month pass 35°C.
- Sun protection: about 10 hours of sunshine a day.
Each line is a threshold over the ten-year figures above, not advice from anywhere else.
Before you go
Type A and B and C and F plugs at 220 V. Drives on the left. The currency is the Baht. UK Foreign Office: avoid all but essential travel to parts. Global Affairs Canada: Exercise a high degree of caution (with regional advisories). US State Department: Level 1: Exercise Normal Precautions. Everything for Thailand: cost of living, languages, emergency numbers and health.
On arrival in Chiang Rai: the apps, paying, getting around, tipping and the emergency numbers.
