Daily ERA5 maximum and minimum air temperatures were averaged by calendar month across 2015–2024. Wet days count daily precipitation totals of at least 1 mm; the listed value is the average count for that calendar month across ten years. Open-Meteo serves ERA5 on an approximately 0.25° grid; the returned grid point can differ from the requested coordinates. These are model reanalysis averages, not local station normals or forecasts. Angkor’s exposed temple grounds may feel hotter than this city grid. Tourism Cambodia describes November–February as the cooler, drier travel period; the broad label does not quantify crowds. The city grid has fewer average wet days in December, but sunrise and temple conditions vary.

A few January questions
An early temple start works best with breakfast and transport arranged.
Is January a good month for Angkor Wat?
January is generally within the cooler dry season, which suits outdoor temple visits. Start early and expect popular sites to be busy.
Where should I stay in Siem Reap in January?
The Old Market area has restaurants and services close by. Wat Bo is quieter across the river, while north-side resorts need transfers to the temple gates.
Are Siem Reap hotel pools heated in January?
The checked hotel listings mention pools but do not confirm heating. Ask about temperature and pool hours if swimming matters.
Can I visit Angkor at sunrise in January?
Sunrise visits are common, but confirm ticket requirements, gate timing, transport and breakfast arrangements with your guide and hotel.
