General & Geography

The Kingdom of Thailand is a popular holiday destination in Southeast Asia. The capital and largest city of the country is Bangkok with around 8.4 million inhabitants.

Thailand borders the neighbouring countries Malaysia, Laos, Myanmar and Cambodia. The two adjacent seas are the Gulf of Thailand (Pacific Ocean) and the Andaman Sea (Indian Ocean).

More than 90 percent of the Thai population of currently about 68 million people profess Buddhism.

Thailand extends from the southeastern foothills of the Himalayas to the Malay Peninsula. The centre of the country with the capital Bangkok is dominated by the fertile Chao Phraya River.

In northern Thailand (e.g. Chiang Mai and Chiang Rai) mountain ranges dominate, here is also the highest elevation of the country (2565 meters) with Doi Inthanon.

Pattaya and the islands Koh Chang and Koh Samet belong to the region of Eastern Thailand. The palm-fringed region of southern Thailand, which includes popular destinations such as Phuket, Krabi, Koh Samui, Koh Phi Phi, Koh Pha-ngan and Koh Tao, has the greatest tourist significance.

Climate in Thailand

License Information available under 'Proof of Image Sources' The climate in Thailand is generally tropical, but there are regional differences. Northern Thailand has an alternating wet savannah climate with a monsoonal character and three different seasons. The somewhat cooler dry season in the north lasts from the beginning of November to the end of February.

Afterwards, the Thai summer runs from the beginning of March to about the end of May with very hot temperatures, before the rainy season in northern Thailand usually ensures heavy precipitation, high humidity and muggy-warm conditions from the beginning of June to the end of October.

The centre around the capital Bangkok also belongs climatically to the tropical savannah zone in the north and is considered moist with a longer dry season. Southern Thailand, on the other hand, has more constant temperatures throughout the year, which are only subject to minor fluctuations.

The climate on the popular holiday islands is therefore rather humid and tropical all year round. So tropical rains also occur during the north-east monsoon in winter. However, with the summer southwest monsoon, there has been a significant increase in humidity and rainfall.

This rainy season in the south runs similarly as in the north of Thailand from the beginning of June to the end of October. The islands in the southeast (especially Koh Samui) have less rainfall and a shorter rainy season than the areas in the southwest (e.g. Phuket). May, October and November in particular are very humid.

    Jennifer, 31 years old was there in October

    My partner and I were in Thailand for a month. From north to south.
    In the north it was pleasantly warm, one could always leave the house well in shorts and shirt, in the evening one needed a thin jacket from time to time.
    In the south it was always warm, something warm than in the north. We never wore anything long there. On two days it rained heavily for 2-3 hours when we were on Koh Tao, otherwise it was always nice.
    In any case, one must not forget the sunscreen, even if one”only” takes cultural days and does not lie on the beach! For women it is always important before going to a temple, even if it is too warm to have a scarf to cover their shoulders or knees (often on site as a loan).
    It was a dreamlike holiday a beautiful country with its different facets.

    Annika, 33 years old was there in September

    We spent a few days in the Phuket, Khao Lak and Koh Phi Phi region at the end of September 2015. Of course, we knew beforehand that it was still the rainy season, so we had to expect rain, clouds and turbulent seas. In the end it was very changeable: We had great weather on Koh Phi Phi, but mainly rain in Phuket. Khao Lak was mostly fine meanwhile.

    Weather Rating: 2 stars – Tricky
