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 | 31°C |
|---|---|
| Nightly low | 24°C |
| Feels like, afternoon | 37°C |
| Rainy days, 1 mm or more | 22 · 364 mm |
| Humidity | 86% |
| Sunshine | 7.4 h/day |
| Daylight | 12.2 h/day |
| 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 Siem Reap, 39 km from the airport (SAI): ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.
