Weather in July in Cambodia is a whole thing, let me tell you. This opening passage is gonna give you the lowdown on what’s good (or bad) about the weather in Cambodia during July.
The weather patterns in Cambodia during July are pretty wild, tbh. The month brings high temperatures and insane humidity rates due to the tropical climate. It’s no surprise that Cambodia gets super hot and humid in July.
Weather Patterns in Cambodia During the Month of July

The month of July marks the beginning of the southwest monsoon in Cambodia, bringing with it a shift in the country’s weather patterns. The prevailing wind patterns during this time play a significant role in the temperature fluctuations experienced throughout the country. In this section, we will delve into the details of the wind patterns and their impact on the temperature, as well as explore the differences between land-sea breezes and valley breezes in the context of Cambodia’s geography.
Prevailing Wind Patterns
The southwest monsoon brings strong winds from the Indian Ocean, resulting in a significant impact on Cambodia’s temperature patterns. The winds are characterized by high wind speeds, often exceeding 30 km/h, which contribute to the formation of thunderstorms and heavy rainfall. The monsoon winds are also known to bring warm and humid air from the Indian Ocean, leading to an increase in temperatures throughout the country.
The southeast trade winds also play a crucial role in shaping the country’s weather patterns during this time. However, the influence of these winds is relatively weaker compared to the southwest monsoon.
Difference Between Land-Sea Breezes and Valley Breezes
The geography of Cambodia, being a low-lying country with a mix of land and sea, creates specific conditions that give rise to land-sea breezes and valley breezes.
Land-sea breezes are a phenomenon that occurs when the temperature difference between land and sea creates a breeze. In Cambodia, the land-sea breezes are influenced by the vast Tonle Sap Lake and the surrounding land masses.
Valley breezes, on the other hand, occur when a valley’s temperature drops as the sun sets, causing a temperature difference between the valley and the surrounding areas. In Cambodia, the valleys surrounding the Tonle Sap Lake are particularly susceptible to valley breezes.
Temperature and Humidity Levels
| City | Average Temperature (°C) | Average Humidity (%) |
|---|---|---|
| Phnom Penh | 28-30°C | 70-80% |
| Siem Reap | 29-31°C | 65-75% |
| Beach Towns (Kampot, Sihanoukville) | 28-30°C | 75-85% |
These temperature and humidity levels are representative of the overall weather conditions in Cambodia during the month of July.
Conclusion
In conclusion, the prevailing wind patterns and temperature fluctuations in Cambodia during the month of July are shaped by the southwest monsoon and the geography of the country. Understanding the differences between land-sea breezes and valley breezes is crucial in grasping the nuances of Cambodia’s weather patterns.
Rainfall and Storm Frequency in July

Cambodia’s monsoon season, which typically begins in May or June, peaks in July, bringing significant rainfall and storm activity to the country. This period is critical for agricultural activities, water resources management, and disaster preparedness.
During July, the southwest monsoon dominates the weather patterns in Cambodia, resulting in increased moisture and instability in the atmosphere. This leads to the formation of low-pressure systems, tropical storms, and heavy rainfall events. Understanding the rainfall and storm patterns in July is crucial for mitigating the impacts of these events on the environment, communities, and infrastructure.
Historical Records of Rainfall in Major Cities
Major cities in Cambodia experience varying levels of rainfall during July, with some receiving significantly more than others. According to historical records, the city of Phnom Penh, the capital, receives an average of around 240 mm of rainfall in July, while the coastal city of Sihanoukville receives approximately 300 mm. In contrast, the mountainous region of Ratanakiri, which is prone to landslides, receives significantly more rainfall, with an average of around 400 mm in July.
| City | Average Rainfall (mm) | Notable Years with Excessive Rainfall |
| — | — | — |
| Phnom Penh | 240 | 2008 (400 mm), 2011 (320 mm) |
| Sihanoukville | 300 | 2013 (450 mm), 2017 (380 mm) |
| Ratanakiri | 400 | 2010 (500 mm), 2015 (420 mm) |
Correlation between Monsoon Activity and Storm Frequency, Weather in july in cambodia
The southwest monsoon plays a critical role in shaping the storm patterns in Cambodia during July. As the monsoon axis shifts southward, the country experiences an increase in moisture-laden air from the Indian Ocean, leading to the formation of low-pressure systems and thunderstorms. These systems can intensify into tropical storms or even typhoons, bringing strong winds and heavy rainfall to the region.
The frequency of storm events in Cambodia during July is closely linked to the strength of the monsoon. Years with a stronger monsoon typically experience more frequent and intense storm events. Conversely, years with a weaker monsoon tend to have fewer storm events, often resulting in drought-like conditions.
Weather-Related Hazards in July
The frequent storm activity and heavy rainfall during July pose significant threats to Cambodia’s communities, infrastructure, and environment. Some of the notable weather-related hazards include:
Flash Flooding
The rapid onset of heavy rainfall in July can cause flash flooding, particularly in urban areas, resulting in damage to infrastructure, displacement of people, and loss of life.
According to the National Committee for Disaster Management, flood-related incidents in Cambodia result in an average of $10 million in damages and affect over 100,000 people each year.
Landslides
The heavy rainfall and strong winds associated with tropical storms can trigger landslides, particularly in mountainous regions, causing loss of life, damage to property, and disruption to critical infrastructure.
Thunderstorms
Thunderstorms are a common occurrence in Cambodia during July, bringing strong winds, lightning, and torrential rainfall. These storms can result in property damage, injury, and even loss of life.
