Chon Buri is a coastal province on Thailand's Eastern Seaboard, best known for the resort city of Pattaya and its string of sun-drenched beaches along the Gulf of Thailand.

Best Time to Visit

Months to Avoid

May to October

Gulf monsoon season brings heavy rainfall, high humidity and choppy seas that can make Ko Lan ferry crossings uncomfortable. Some days see all-day downpours, though sunny spells still occur — showers are often brief but intense.

Climate Overview

Chon Buri has a tropical monsoon climate with three distinct seasons: cool-dry (November–February), hot-dry (March–May) and wet (June–October). The province lies on the western shore of the Gulf of Thailand, receiving the tail end of the southwestern monsoon from May onward. Average annual temperature is 28°C (82°F) with humidity typically 70–85%.
