Cambodia is warm year-round. Dry season, running November through May, encompasses two seasons: cool (November-February) and hot (March-May). Cool season is when most travellers visit Cambodia. Wet season runs May through September and is a good time to visit Angkor.

Dress modestly, covering your shoulders and knees, when visiting religious places, the countryside, and the Ho Chi Minh Mausoleum. Before visiting a temple or pagoda, don't forget to take off your hat and shoes. Don't wear shorts, miniskirts, or bare shoulders. You should never turn your back on a Buddha statue or image.

Ask the aid of a Khmer speaker because there might not be an English-speaking operator on the line:
Ambulance: 119
Fire department: 118
Police: 117 or 118

In Cambodia, there hasn't been much of a concern with physical safety, according to reports. Be on the lookout for pickpockets and always keep any expensive electronics and documents in a safe location because pickpockets may operate in well-known tourist spots.

- Avoid raw meat and fish
- Prefer boiled or cooked vegetables instead of raw vegetables.
- Wash your hands frequently
- Drink a lot of water to keep your body hydrated, and avoid strong physical exercise before you get used to the heat.
- Use insect repellent several times a day if you are in a humid region of Cambodia, and at night time in the whole country. Wear long sleeved/legged clothes to avoid mosquito bites, mostly at night time also.

Always respect local traditions out of consideration for the people who gladly welcome visitors. There are a few things to keep in mind while you explore this stunning nation:
Do
- Always get someone's permission before taking their picture, especially in remote areas.
- To combat mosquitoes, have insect repellent on hand. No vaccines are required, however it is advisable for anyone considering a trip to Cambodia to think about getting some and packing some medication because it may not be available everywhere.
- Remove your shoes before visiting temples, pagodas, and other places of worship.
- In such places, bare skin is discouraged; stay away from shorts, cover your shoulders, and take off your cap.
- When entering someone's home, take off your shoes. If you are asked to come to a meal, bring a small present; flowers or fruit are acceptable.
- If you're going to a wedding in Cambodia, provide a monetary gift.
- As you offer and receive, use both hands.
- If you are being introduced to someone, bow slightly forward while clasping your hands together (as if in prayer). Use common sense; it is generally formal and not always anticipated.
Don’t
- Use your feet to indicate, as they are thought to be the dirtiest part of the body.
- Don't touch anyone's head; it's the most significant and private area of the body.
- Under no circumstances should you begin eating before your host.
- If you're a woman, touch monks or give them something.
- Show excessive affection in front of others.
