The best time to visit Angk Ta Saom is during the dry season, which typically runs from November to April.
During these months, the weather is generally sunny and pleasant, with lower humidity and less chance of rain. This makes it ideal for exploring the local area, visiting the nearby temples, and enjoying outdoor activities like boat trips on the Tonlé Bati lake without interruption. The cooler temperatures, especially from November to February, make for a more comfortable experience when walking around.
For travellers who prefer slightly fewer crowds and are comfortable with a bit more heat, late April can also be a good option, just before the monsoon season fully begins.
