The best time to visit Thailand is between November and February, when the climate is relatively cool and dry (25-32°C). Arriving between March and May will put you right through Thailand’s summer, when temperatures can climb above 40°C. The monsoon season (June-September) is usually very wet and humid, and national parks and waterfalls are at their best.
Tourists from many countries, including Australia, New Zealand, the US, UK, Germany, France and Singapore, do not require a visa when entering Thailand and can stay for 30 days. Thai authority requires at least six months validity remaining on the passport. Check the Thai embassy’s website.
Suvarnabhumi International Airport in Bangkok is the main air gateway into Thailand. Thai Airways, Qantas and Emirates (till the end of May 2019) operate direct flights from Australia to Bangkok; Jetstar flies to Bangkok from Melbourne and to Phuket from Sydney. Other carriers that provide connections from Australia include Singapore Airlines, Malaysian Airlines, Scoot and AirAsia.
