Climate

Cambodia has a tropical monsoon climate that varies by region and season:

  • Central Cambodia (Phnom Penh, Siem Reap): the tropical climate brings hot, dry winters (25–30°C) and hot, humid, rainy summers (30–35°C). The rainy season from May to October brings heavy showers, which are usually brief and often occur in the afternoon, while the dry season lasts from November to April.
  • Coast (Sihanoukville, Kep): the coastal climate is more humid, with hot summers (28–34°C) and milder winters (24–30°C). Monsoon rainfall is particularly heavy here, turning the region lush and green from May to October. Conditions for beach holidays are best from November to February.
  • North-east (Ratanakiri, Mondulkiri): the highlands have a slightly cooler climate, with pleasant summers (20–28°C) and cooler winters (15–25°C). Rainfall is also concentrated mainly during the monsoon season, but temperatures remain more comfortable throughout the year than in lower-lying areas.

Best time to travel to Cambodia:

  • Cultural trips (Angkor Wat, Phnom Penh): November to March is ideal, as the weather is dry and more pleasant, making it perfect for exploring temples and cities.
  • Beach holidays (Sihanoukville, Koh Rong): December to February offers sunny weather and warm temperatures, ideal for a beach holiday.
  • Nature experiences (Ratanakiri, Mondulkiri): the best time is from November to February, when the weather is cooler and the landscape is particularly lush.
Communications
  • Using a mobile phone in Cambodia may incur roaming charges. Travellers are advised to check the applicable roaming fees before departure and, where necessary, purchase a suitable roaming package to reduce costs.
  • Free Wi-Fi is available in cafés, hotels and public spaces.
  • To avoid roaming charges, it can be worthwhile purchasing a local SIM card. Cambodia’s main providers – Cellcard, Smart Axiata, Metfone and qb – offer affordable tariffs and reliable network coverage for travellers.
Tourist attractions
  • Angkor Wat – The largest religious complex in the world and a UNESCO World Heritage Site, renowned for its impressive architecture.
  • Bayon Temple – Famous for the smiling faces carved into stone at Angkor Thom.
  • Royal Palace – A magnificent palace in Phnom Penh, serving as a cultural landmark and the residence of the royal family.

Food and drink

Cambodian cuisine is a harmonious blend of fresh ingredients, local specialities and influences from Thailand and Vietnam. From street-food stalls to upmarket restaurants, visitors can look forward to a true feast of flavours.

  • Amok: An iconic dish of steamed fish in a creamy coconut curry sauce, served in a banana leaf – mild, aromatic and a must-try for every visitor.
  • Lok Lak: A popular beef dish marinated in a flavourful sauce and often served with fresh vegetables and rice. Traditionally, it is accompanied by an egg and a lime-and-pepper dipping sauce.
  • Nom Banh Chok: Cambodia’s take on rice noodles, usually served for breakfast. A light curry broth and fresh herbs make this dish particularly refreshing.
  • Khmer BBQ: A popular style of grilling in which different types of meat, such as beef, pork and seafood, are cooked directly at the table – perfect for a sociable evening.
  • Street food: From grilled meat skewers and fried noodles to crispy insects, Cambodian street food is a real adventure and offers affordable yet tasty dishes.
  • Desserts: Sweet treats such as sticky rice with mango or Nom Plae Ai (rice balls filled with palm sugar) are typical Cambodian desserts that are sure to delight anyone with a sweet tooth.
  • Fresh fish and seafood: Particularly in coastal regions, fresh seafood such as prawns and squid is prepared in many different ways – grilled, fried or steamed, it is always a treat.
Etiquette tips
  • Greetings: in Cambodia, the traditional greeting is the “Sampeah”, where the hands are placed together in front of the chest and the head is slightly bowed. The higher the hands are held, the more respectful the gesture. A simple smile is also always appreciated.

  • Saying please and thank you: friendliness and politeness are very important. A simple “Akun” (thank you) shows respect and is always appreciated. “Som” is used for “please”.

  • Clothing: shoulders and knees should be covered when visiting temples and religious sites. Modest, non-revealing clothing is also appreciated outside religious places.

  • Dining etiquette: it is polite to wait until the host or eldest person begins eating. Meals are often eaten with a spoon and fork, while knives are less commonly used. Food is frequently shared, and it is considered polite to take a small portion onto your plate.

  • Smoking: smoking is not permitted in enclosed spaces such as restaurants or temples. It is considered impolite to smoke without asking for permission first.

  • Tipping: tipping is not expected, but it is common in tourist areas. In restaurants or hotels, a tip of around 10% is appropriate. For smaller services, a small gesture is always appreciated.

Health situation
  • Tap water: tap water in Cambodia is not safe to drink. Bottled water, which is widely available, is recommended. Travellers should also take care when brushing their teeth or consuming ice in drinks and use safe bottled water whenever possible.
  • Vaccinations: no mandatory vaccinations are required to enter Cambodia. Before travelling, standard vaccinations should be checked and updated if necessary. Vaccination against hepatitis A is recommended. For longer stays or particular exposure, vaccination against dengue fever, hepatitis B, typhoid, rabies and Japanese encephalitis is also recommended.
Medical care
  • Medical care in Cambodia is not comparable to that available in Europe and often falls short in terms of technical equipment, facilities and hygiene standards. Medical options are particularly limited in rural areas. Travellers with chronic illnesses or conditions requiring ongoing treatment may face an increased health risk when travelling to Cambodia. 
  • Travellers are strongly advised to take out comprehensive international health insurance before departure that also covers emergency repatriation.
  • Bring a travel medical kit tailored to your individual needs and protect medicines from high temperatures while travelling.
Current security situation
  • Before and during your trip, keep informed about the current situation through the media and remain in contact with your tour operator.
  • Travellers in Cambodia should remain particularly vigilant, as crime levels are higher in some areas. Theft occurs regularly, especially in cities such as Phnom Penh, Sihanoukville and Siem Reap, as well as in busy tourist areas. In rare cases, armed robberies or other violent offences, including sexual assaults, may also occur. Travellers are therefore advised to remain alert at all times and take appropriate precautions.
  • Further information on the current security situation is available on the website of the Federal Department of Foreign Affairs (FDFA).

Road traffic
  • For car hire, a Swiss driving licence is recognised; however, an International Driving Permit is recommended.
  • For longer stays in Cambodia, a Cambodian driving licence must be obtained.
  • Driving in Cambodia can be dangerous, as traffic regulations are often disregarded and road conditions are poor in many regions.

  • Blood alcohol limit: 0.1 ‰.
Public transport

Public transport in Cambodia is less developed, but it still offers travellers several ways to explore the country.

  • Long-distance trains: Cambodia’s railway network consists of two main lines: the Northern Line and the Southern Line, with a total length of around 650 kilometres. The Southern Line connects Phnom Penh with Sihanoukville, while the Northern Line links Phnom Penh with the Thai border. Train services are slow and irregular, but offer an interesting way to experience the landscape.

  • Regional trains: Regional rail services are limited and generally irregular, as freight traffic takes priority. For shorter journeys, travellers usually rely on buses.

  • Coaches: Coaches are the main form of public transport in Cambodia, particularly for longer journeys between cities such as Phnom Penh, Siem Reap and Sihanoukville. Various private operators offer services in different comfort classes. Long-distance coaches are often cheaper than trains and may offer amenities such as air conditioning and reclining seats.

  • Underground: Cambodia does not have an underground system.

  • Boats: Cambodia has several ferry connections, particularly from Sihanoukville to the islands of Koh Rong and Koh Rong Samloem. These boats are a popular means of transport for tourists visiting the islands. During the rainy season, passenger boats also operate on some waterways, particularly across Tonlé Sap between Siem Reap and Phnom Penh. 
  • Tickets: Coach tickets can be purchased at bus stations, travel agencies or online via platforms such as Camboticket and BookMeBus. Train tickets can be purchased at railway stations, although online booking is often unavailable.
  • Apps: Grab is the most popular app for urban transport, offering both taxi and tuk-tuk services. Google Maps is also useful for route planning and provides reliable information on public transport connections.
Air traffic

There are currently no direct flights from Switzerland to Cambodia. Travellers generally need to connect via major hubs such as Bangkok, Singapore or Hong Kong to reach Phnom Penh or Siem Reap.

The main airports in Cambodia are:

  • Phnom Penh International Airport (PNH), Phnom Penh – The country’s main international airport, handling the majority of international flights.
  • Siem Reap International Airport (REP), Siem Reap – The country’s second-largest airport, mainly serving travellers visiting the world-famous temples of Angkor Wat. It offers both domestic and international connections.
  • Sihanoukville International Airport (KOS), Sihanoukville – A smaller airport in the south of the country that is becoming increasingly important for tourism and offers domestic as well as some international flights.

Cambodia’s main domestic airlines are Cambodia Angkor Air and Lanmei Airlines. International airlines such as Thai Airways, Singapore Airlines, Bangkok Airways and AirAsia connect Cambodia with destinations across Asia and beyond.
