Thailand has a tropical climate that is hot and humid year-round, with distinct wet and dry seasons shaped by the southwest and northeast monsoons. The live forecast above gives current conditions, but most of the country sees average highs of 30–35°C, with cooler spells in the north during winter evenings.
What are the main seasons for Thailand weather?
Thailand’s year splits into three broad phases. The hot season runs from March to May, with temperatures often topping 38°C inland. The rainy (southwest monsoon) season lasts June to October, bringing heavy downpours, especially in the west and south. November to February is the cooler, drier period, when the northeast monsoon brings lower humidity and clearer skies, making it the most comfortable time for travel.
How does weather vary between north and south?
Northern regions such as Chiang Mai experience a wider temperature range, with cooler nights from November to February. Southern coasts and islands (Phuket, Koh Samui) stay warmer and more humid; their rainy season peaks at different times depending on whether they face the Andaman Sea or the Gulf of Thailand. Inland Bangkok, by contrast, sees a sharper contrast between dry and wet months.
When does the monsoon hit Thailand?
The southwest monsoon typically arrives in late May and lasts through October, bringing heavy rain to the west coast and central plains. The northeast monsoon (November–February) brings drier air from China, cooling the north and east.
What should I pack for Thailand weather in November?
Light cotton clothing and a waterproof jacket are essential. Even in the dry season, brief tropical showers can occur. Sunglasses, sunscreen and a hat are needed for daytime heat, while northern evenings may require a light jumper.
Is there a Thailand weather warning today?
Heavy rain and flood warnings are common during the monsoon. Check the live forecast above and follow updates from the Thai Meteorological Department. Flash flooding can affect low-lying areas, particularly in Bangkok and northern provinces.
