Country Summary

This page presents high-level information for Thailand's climate zones and its seasonal cycle for mean temperature and precipitation for the latest climatology, 1991-2020. Climate zone classifications are derived from the Köppen-Geiger climate classification system, which divides climates into five main climate groups divided based on seasonal precipitation and temperature patterns. The five main groups are A (tropical), B (dry), C (temperate), D (continental), and E (polar). All climates except for those in the E group are assigned a seasonal precipitation sub-group (second letter).  Climate classifications are identified by hovering your mouse over the legend. A narrative overview of Thailand's country context and climate is provided following the visualizations.

Thailand lies in the southeastern part of the Asian mainland. Located in the tropical region, Thailand has a climate that is relatively warm throughout the year. The agricultural sector contributed 10.5% to 2014 gross domestic product, the industry sector 36.9% and the service sector 52.7%. The 2015 population in Thailand was 68 million. The proportion of the urban population to the total population has also gradually increased following the expansion of the economy. Land is an important natural resource that supports the agricultural and non-agricultural sectors. In December 2004, a magnitude 9.3 earthquake triggered the Indian Ocean tsunami that hit Thailand, killing over 250,000 people and causing billions of dollars of damage. In areas where natural buffer zones remained inland territories were protected by large mangrove forests that dulled the wave’s impact and dissipated its energy. Climate change threatens all key sectors of Thailand’s economy: agriculture, tourism, and trade.

The first five-year national strategy on climate change in Thailand was released in 2008. Currently, the second five-year strategy is in place. The Ministry of Natural Resources and Environment’s Office of Natural Resources & Environmental Policy and Planning is responsible for preparing and coordinating the strategy. In addition, the country has also prepared a Climate Change Master Plan that provides a framework for all adaptation, mitigation and capacity building policies and action plans for climate change from 2012-2050. Thailand ratified the Paris Agreement on September 21, 2016 and its Nationally Determined Contribution can be found here.
