Sun protection is essential when exploring outdoor sites like Angkor Wat, where you may spend hours walking between temples with limited shade. Apply SPF 30 or higher sunscreen every couple of hours, and bring a wide-brimmed hat and lightweight long-sleeved clothing.
Cloud cover offers limited protection; you can still get sunburned on overcast days. The UV index is particularly high between 10:00 AM and 3:00 PM. Many travelers prefer to explore temples during early morning hours, retreat to air-conditioned spaces during midday, and resume activities in the late afternoon when temperatures and sun intensity decrease.
