The Monsoon Season Context
To truly grasp the intricacies of Thailand’s weather in June, it’s crucial to understand the broader meteorological phenomenon at play: the Southwest Monsoon.
Thailand’s weather is influenced by monsoonal winds, which, driven by temperature differences between the Asian landmass and the Indian Ocean, result in marked seasonal changes. By June, the Southwest Monsoon is in its early stages, having transitioned from the dry Northeast Monsoon that dominates the cooler months.
This southwest airflow brings with it moist air from the Indian Ocean, signaling the onset of the rainy season in Thailand. As the moisture-laden winds encounter the mountainous regions and varied topography of the country, they lead to increased cloud cover and precipitation.
However, it’s worth noting that the intensity and pattern of the monsoon can differ significantly across regions. For instance, while the western and southwestern parts of the country might experience heavier showers, other regions may still enjoy periods of sunshine and lighter drizzles.
Temperature in June
When it comes to temperature, June remains consistently warm throughout Thailand, reflecting its tropical climate. However, there are some regional variations worth noting.
Average Temperatures
Throughout June, Thailand generally experiences average high temperatures ranging from 30°C to 35°C (86°F to 95°F). The lows, which occur mostly during the nighttime, hover between 24°C to 28°C (75°F to 82°F).
Regional Variations
Northern Thailand (Chiang Mai, Chiang Rai): This region tends to be slightly cooler than the rest of the country. Expect average highs around 32°C (90°F) and nighttime lows dipping to approximately 24°C (75°F).
Central Thailand (Bangkok, Ayutthaya): The central plains, including the bustling city of Bangkok, usually see daytime highs of about 33°C to 35°C (91°F to 95°F) and nighttime temperatures of around 26°C to 28°C (79°F to 82°F).
Southern Thailand (Phuket, Krabi): Being closer to the equator, the southern regions maintain a fairly consistent temperature throughout the year. In June, anticipate highs of around 32°C (90°F) and lows of 25°C (77°F).
Northeastern Thailand (Isaan region): This area experiences temperatures similar to the central region, with highs reaching up to 34°C (93°F) and nighttime temperatures settling at about 26°C (79°F).
Rainfall in June
The advent of the Southwest Monsoon implies that June marks the onset of increased rainfall across Thailand. While showers can be anticipated, their frequency, duration, and intensity can differ based on the region.
Expected Rainfall Amounts and Frequency
Throughout June, Thailand generally witnesses rainfall amounts averaging between 100mm to 200mm. However, it’s not unusual for some regions to receive higher totals.
These showers often manifest as short, intense bursts, typically in the afternoon or evening, rather than prolonged periods of rain.
Differences Between Regions

| Southern Thailand (East Coast) | ~100mm | Lighter showers |
| Northeastern Thailand | ~150mm | Brief but intense rain showers |
Northern Thailand (Chiang Mai, Chiang Rai): The northern regions experience a moderate amount of rainfall in June, averaging around 100mm to 150mm. Rain showers tend to be interspersed with sunny intervals.
Central Thailand (Bangkok, Ayutthaya): The central areas, including Bangkok, can expect slightly heavier rainfall than the north, with totals ranging between 150mm to 180mm. While showers are common, they’re usually followed by clear skies.
Southern Thailand (Phuket, Krabi): Southern Thailand exhibits a unique rainfall pattern due to its two coastlines. The west coast, including places like Phuket, sees more substantial rains in June, with totals often exceeding 200mm. Conversely, the east coast (e.g., Koh Samui) receives lighter showers, averaging around 100mm.
Northeastern Thailand (Isaan region): The northeastern part of the country witnesses rainfall amounts similar to those in the central regions, hovering around 150mm. Rain showers here can be brief but intense.
Humidity Levels
Humidity plays a significant role in how the weather is perceived, especially in tropical countries like Thailand. In June, the increased rainfall brought on by the Southwest Monsoon leads to heightened humidity levels across the nation.
Average Humidity Percentage
During June, Thailand experiences average relative humidity levels ranging from 70% to 85%. Morning hours often start with higher humidity, which might decrease slightly as the day progresses, especially after rainfall.
Tips on Staying Comfortable Amidst High Humidity
Living in or visiting a high-humidity environment can be a new experience for many. Here are a few practical suggestions to help cope:
Light Clothing
Opt for lightweight, breathable fabrics such as cotton or linen. Loose-fitting clothing can also be more comfortable and help with air circulation.
Stay Hydrated
High humidity can lead to increased perspiration. Regularly drinking water helps replenish lost fluids and keeps the body cool.
Indoor Activities
Planning indoor activities during peak humidity hours can offer relief. Modern buildings, especially in urban areas, often have air conditioning, which can be a respite from the outside mugginess.
Use Fans or Air-conditioners
If staying indoors, using fans or air conditioners can help reduce the perceived humidity. When using air conditioners, setting them to a moderate temperature can make transitioning to the outside environment easier.
Shower More Often
Taking more frequent showers, especially cool ones, can provide immediate relief from the sticky feeling that high humidity can induce.

Embracing the Rain: Rain isn’t always viewed as a disruption. Many Thais see it as a refreshing break from the heat, a time to slow down, enjoy a warm beverage, or even play in the downpour.
Dressing Like a Local
Light and Loose: Thais often wear light-colored, loose-fitting clothing, which allows the body to breathe and helps combat the high humidity.
Footwear Choices: Flip-flops or slip-on shoes are commonly worn, as they are easily removed (a cultural practice when entering homes or certain businesses) and dry quickly after a downpour.
Cultural Nuances in the Rain
Water as a Blessing: In Thai culture, water is often associated with blessings and purification. This perspective transforms the perception of rain from merely a weather occurrence to a spiritual event.
Street Food: Rainy days see a shift in street food offerings. Warm, comforting dishes like soups or noodle broths become more prevalent, providing both warmth and a culinary treat.
Practical Local Adaptations
Motorbike Preparations: Many locals travel on motorbikes. During the rainy season, it’s common to see them with rain ponchos specifically designed with extended back sections to cover the entire bike and its rider.
