Thailand Climate and Weather Patterns

Thai climate and weather patterns

Thailand is a tropical country, offering varied climates depending on where you visit. The northern mountains and central regions such as Chiang Mai and Bangkok experience distinct climates than the southern peninsula with its beaches.

From March until mid-May, temperatures in the Philippines can soar above 40 degrees Celsius (104 F). Thankfully, rainy season brings some respite during these hot months.


Thailand’s tropical climate can be divided into three distinct seasons by monsoon winds. Each area of the country experiences different rainfall amounts and dates during these seasons, which make up a unique experience for visitors to this tropical country.

Summer in Australia typically lasts from March to June and brings with it little rainfall, high humidity levels and temperatures that can reach 40 degrees Celsius. Even at night there is little relief from the intense heat.

For a tropical holiday tan, snorkeling in turquoise waters or exploring vibrant Thai culture, November to February is the best time to visit. Temperatures and humidity are cooler than during other months of the year and there’s more sunshine at this time of year.

While Northern Thailand experiences subtropical weather, Southern Thailand enjoys a tropical rain-forest climate with warmer temperatures and less rainfall. On average, daily temperatures in the South reach 29 degrees Celsius – perfect for swimming and taking in all of Thailand’s breathtaking sights and sounds.

It is essential to be aware that water temperature is determined not only by solar radiation within a region, but also ocean currents. Thus, the warmest waters can be found in Southern Thailand.

In the North and Central regions, humidity levels are highest during summer. Therefore, you’ll want to bring along some lightweight jackets in wintertime when night time temperatures can drop as low as 10degC (50degF).

The rainy season, which lasts from July to October, is marked by accumulations of precipitation that can reach up to 20 centimeters per day. Unfortunately, storms are often brief in duration – lasting only an hour or two before clearing away.


Thailand experiences a tropical climate with hot, humid days. The weather pattern is determined by both the sun’s position in the sky and Earth’s magnetic pole movement. The northern reaches of Thailand experience hot and dry weather from March to June, while southern peninsular areas experience monsoon rains during summer.

Bangkok’s climate can get particularly hot from March to May (known as ruedu ron). Therefore, you should be prepared for high temperatures and plenty of humidity. Don’t forget to pack a hat, sunscreen and waterproof jacket just in case – the sun can be intense at this time of year!

The cool season, which runs from November to February, is the most pleasant time of the year to travel. Humidity levels decrease and temperatures are milder due to a north east breeze.

Summer in Thailand is the perfect time for working on your tan, snorkelling in pristine seas and discovering its stunning culture. Not only that but this period also makes for a great opportunity to visit Bangkok as well as book accommodations during Songkran Festival!

Thailand’s peak travel season is from April through October, when temperatures and rainfall are generally low. Unfortunately, some of the heaviest rains still fall during this period.

It is important to bear in mind that rainy seasons in Thailand do not follow a standard calendar. On the west coast of the country, rainfall typically occurs from April through October while on the Gulf and offshore islands it rains from October until January.


Thailand has a tropical climate, with hot and humid conditions mainly along the coastline. Northernmost regions, especially along Laos’ and Burma’s borders, experience cooler climates due to mountainous terrain.

The southwest monsoon, which brings warm and humid air from the Indian Ocean, is strongest between May and October. Additionally, tropical cyclones may impact this region with heavy downpours.

Though monsoon rains may seem to ruin the beaches, they actually offer some respite from the heat. Unfortunately, they tend to linger into evenings and can lead to flooding.

During the rainy season of July to October in Thailand, temperatures can soar to extremes. Days tend to be sunny but thunderstorms and heavy downpours often hit in the afternoon or evening.

It is essential to remember that Thailand is vulnerable to tropical cyclones, which can wreak havoc. Cyclones tend to occur more frequently in Southeast Asian regions and are most likely to reach continental Thailand from June through December.

Thailand’s ideal time to visit is between November and February, when temperatures are cooler and drier than summertime and there are fewer tourists around.

In general, Thailand’s southern regions tend to be drier and have lower humidity levels than their central and northern counterparts. This makes it an ideal time for visiting national parks where many waterfalls are at their most picturesque.

Summer temperatures in Thailand tend to be high, ranging from 25degC to 40degC. If you aren’t used to these extremes, it may be uncomfortable if you don’t bring along some long sleeve shirts or sweaters for those sweltering days.


Thailand’s southern regions are subject to the annual southwest monsoon, which begins in India and brings a stream of moist air from the Indian Ocean. This causes frequent rainstorms between May and October in these regions.

Although monsoon season can be unpleasant for some travelers, it offers travelers a rare chance to appreciate the country’s stunning natural beauty and take advantage of discounts on accommodations. However, travelers should be aware that there are risks associated with sudden downpours on streets, flash flooding and slippery conditions; thus it’s essential to bring along ponchos and umbrellas when traveling during this period.

Thailand remains a popular tourist destination despite the rainy season. The main benefit of visiting during this period is that there are fewer visitors and hotels are more cost-effective.

It is an ideal time to visit Thailand’s northern regions, as temperatures tend to be cooler during this period. Khao Sok, one of Thailand’s most picturesque national parks, is especially stunning during this period.

Tourists in Thailand should be aware that monsoon season can bring heavy downpours and strong winds. To be prepared, tourists should carry umbrellas or ponchos with them at all times. While these storms usually only last a short while, being prepared helps avoid being caught out in adverse conditions.

The rainy season in Bangkok typically commences around late June and lasts until early October. This period can be especially humid, with heavy downpours taking place during daytime especially during July and August.

In addition to the wet weather, monsoon season can bring about routine flooding in parts of northern and central regions. This is often accompanied by flash floods or mudslides, so visitors planning on going jungle trekking during this period should consult a licensed tour guide about conditions.

Khao Sok

Khao Sok National Park in Surat Thani province of Southern Thailand is home to some of the world’s oldest evergreen jungle and majestic limestone karst mountains. Additionally, this UNESCO world heritage site features waterfalls, rivers and lakes.

No matter what kind of adventurer you are, there is a wealth of activities in the surrounding area to enjoy. Popular choices include jungle camping, lake touring and over-night treks; kayaking and river rafting; wildlife safaris; as well as elephant rides for added excitement!

Khao Sok’s weather can be somewhat unpredictable, but is best predicted by the seasons (see below). Rainfall is most frequent between June and November, while temperatures tend to be lower than other times of year.

In April, temperatures in Surin and Similan Islands typically remain hot and humid with an increased chance of thunderstorms. Daytime highs range from 24C-340C while sea temperatures hover around 280C – making for ideal snorkeling conditions.

September is usually Khao Lak’s wettest month, with high levels of humidity and heavy rainfall hitting the area from mid-September on. Despite these conditions, there are still plenty of sunny spells and rain usually comes down in short bursts rather than lasting hours on end.

October is the last month of Khao Lak’s dry season, featuring a mix of showers and sunshine. Temperatures remain mild at 290C with 8 hours of daily sunshine.

Ratchaprapa Dam and Cheow Larn Lake offer plenty to see and do, including floating bungalows on the shoreline. Alternatively, visitors can visit National Park Headquarters to explore jungle trails. Furthermore, ecotourism activities exist to protect wildlife within the park.
