0 CommentsTraveling to Cambodia is a venture back in time among towering stone temples, meandering jungle rivers, and peaceful seaboard havens. But because the country is shaped by a tropical climate influenced by changing monsoons, when you come is the most significant choice you can make.
The weather in Cambodia is fairly consistent throughout the country, unlike the nearby gigantic multi-climate neighbors. Yet it divides neatly into two separate worlds: an arid-winter-dry and a rainy-winter-wet. If you choose the wrong time, you can end up trekking temple ruins in sweltering 40℃ heat or wading across flooded country roads. Here's a guide that cuts through the textbook banalities to give you a realistic boots-on-the-ground perspective on when to visit Cambodia by weather, crowds, and travel styles.
The Two National Clocks: Dry Season vs. Green Season
Cambodia does not have spring, summer, autumn, and winter. Instead, the entire country operates on a binary weather system driven by tropical monsoon winds.
The Dry Season (November to April)
Then the northeast monsoon prevails in November which brings clear sky and very low humidity. During these first few months (November to February), the weather is as close to ideal as you can get in a tropical country. The warm days, now in the 26-30 degrees range, are accompanied by cool evenings and a refreshing breeze. Planning to visit during these golden months?

However, by the end of March the dry season is about to break. The cool breezes are gone, and the sun is cooking the earth. The two hottest months of the year are March and April, when the temperature often exceeds 38℃(100℉). The humidity is on the rise, making cities such as Phnom Penh and the labyrinthine streets of Siem Reap into hot and sweaty.
The Green Season (May to October)
In May, the southwest monsoon arrives from the sea, carrying moisture, high humidity, and frequent rains. This is the rainy season in Cambodia, but it is rarely raining all day long. The only difference is that the weather runs more or less like clockwork off: mornings are sunny, clear and excruciatingly humid, and come late afternoon you get a sudden, violent rainstorm.
August and September are the most torrential months of this cycle. Pathways in the countryside can disappear under mud during this peak, and rivers flow at their fullest capacity. But, this season does live up to the moniker of the “Green Season” — the parched, beige, countryside turns into an electric green rice farming landscape and waterfalls come roaring to life.
The Overall Best Travel Windows
If predictability and comfort are what you seek in a classic program involving temple visits, city strolls, and beach time, December and January are the best months. The air is crisp, the sky unfailingly blue during this winter high, and you can saunter through outdoor ruins for hours without tiring.
But Asada's peak season for international tourists is coincidentally the best weather. You'll be sharing sunrise over Angkor Wat with thousands of others, and accommodation prices reach their annual peaks.
Travelers looking for a reasonable balance of good weather, reasonable prices and not too busy a scene will find the best compromise would be the 'shoulder' seasons of November and March. November is especially stunning because the monsoons have just passed, so everything is still super green and your reservoirs are full, but the rain is no longer (not so) heavy. March is scorching, but if you get up early, you can avoid both the heat of the day and most of the tourist masses. In short, whether you prefer the sunny days of the dry season or the lush, green landscapes and fewer crowds of the rainy season, Cambodia never fails to mesmerize.

A Realistic Month-by-Month Breakdown
November to February: The Peak Comfort Zone
This is theequally indisputable sweet spot for weather all over Cambodia. January is the month with the lowest rainfall during the whole year. This is definitely the best time for trekking in the Cardamom Mountains, cycling along the Mekong, or hopping in a boat to the southern islands. The problem is all with logistics: the temples are crowded, the boutique hotels sell out months in advance, and the best spots for photographing require a pre-dawn arrival to claim a shooting station.
March & April: The Intense Heat
If you visit in that months you just have to adjust your daily schedule. At noon the heat is thick and inescapable. Touring is a morning and late afternoon activity, with the middle of the day taken up by naps, dips in the pool or visits to air-conditioned buildings. April is also the month of Chol Chnam Thmey (Khmer New Year). As the locals retreat to their home provinces and the cities become a bit quieter, these cultural celebrations, drunken water fights, and general festive atmosphere, provide a fantastic insight into local life—just be prepared for all your business to come to a screeching halt.
May & June: The Transition and Early Rains
May brings the first major relief from the dust and heat in the form of scattered afternoon storms. As June begins, the tourist crowds thin out dramatically. The dust settles, prices begin to drop, and the landscapes start their rapid transformation back to green. It is a highly underrated time for travelers who don't mind carrying a rain jacket in exchange for quiet temple trails.
July to September: The Depth of the Monsoon
It's the middle of the rainy season and September is the wettest month of all. Travelling in this block of time need a relaxed mentality and the feet must be flexible. Certain dirt roads in outlying provinces such as Mondulkiri or Ratanakiri may be washed away. But the architectural payoff is immense: the stones of Angkor Wat blacken in the rain, the surrounding moats run over, and moss shrouds the ruins, giving an atmospheric, mystical effect that the hordes of the high-season never lay eyes on.
October: The Clearing Month
October is a fantastic month of transition. The monsoons start receding, and the air is fresher, and the whole land is drenched in shades of green. The crowds have not yet descended and hotels are still offering off-season rates. It is also Tonle Sap Lake time, when the lake expands to its maximum size, so this is also the best month to go to the floating villages by boat.
Choosing Your Timing Based on Travel Styles
For the Archeology Buff and Temple Explorer
If your primary goal is to marvel at the scale of the Angkor Empire, you need to choose between physical comfort and visual solitude. To explore comfortably without dripping sweat, stick to November through February.
However, if you want to experience ancient temples like Ta Prohm or the remote outer ruins of Beng Mealea without a sea of selfie sticks, brave the green season months of June to August. The short afternoon rain bursts are an easy trade-off for having ancient, jungle-entwined monuments virtually to yourself.
For Island Hoppers and Beach Goers
The south of Cambodia, including the laid-back towns of Kep and Kampot and the tropical islands of Koh Rong and Koh Rong Sanloem, is very seasonal.
- The Best Time Window: Enjoy perfectly calm seas, bright blue skies and high visibility underwater for snorkeling and diving from December through February.
- When Not To Go: July to September. The southwest monsoon batters the coast, posing the risk of traumatic waves, cancelling ferries in droves and dousing island life with horizontal rain.
For Wildlife and River Cruising
To travel on the waters of Cambodia, this varies according to water depth. If your aim is a Mekong River cruise, or to navigate the enormous waters of Tonle Sap Lake to visit floating villages, the months of high water from September to November are unbeatable. In this period the flow of the Tonle Sap river is reversed, and it fills the basin to the brim which enables boats to sail deep inside flooded mangrove forests and lakeside villages that are totally high and dry during the rest of the year.
Crucial Practical Tips for Navigating the Climate
Dressing for the Heat and the Culture: No matter what month you go, Cambodia is hot. Breathable linen or loose cotton clothing is your armor. Keep in mind that places such as the Royal Palace in Phnom Penh and the temples of Angkor do require modest dress – shoulders and knees need to be covered. Pack lightweight wraps or loose long pants so you can stay cool while honoring local traditions.
Hydinning Strategies: The combination of tropical heat and physical exertion while climbing steep temple steps is exhaustingly draining. Carry water at all times and you may also want to bring some electrolyte packets in your daypack, particularly if traveling in the heat of March and April.
The Rain-Off: Don't even think about bringing a heavy, suffocating raincoat during the green season. Yes, get yourself a cheap, lightweight poncho locally or bring a compact umbrella. The storms are warm, and though a poncho allows for a lot more airflow if you are walking. And most importantly, make sure your daypack is water-resistant or use dry bags to protect your camera gear and electronics from sudden showers. Interested?
