The short answer
When to go to Ayutthaya
The best months are November to February, when it is dry and the days are warmer than the nights. December and January are driest and most comfortable, but also busiest. March to May is hot, with April the hottest month, and June to October is the rainy season, with the heaviest rain in August and September. Older travellers will find the ruins most manageable early in the morning in the cool season; in the heat, restrict outdoor stops to the first hours after opening and use the National Museum as a cool break.
