The best time to visit Thailand depends on what type of experience one desires. If you're looking for a cooler climate, November is the beginning of the cool season and is an ideal time to travel. For those interested in lower costs, the rainy season from July to October may be the most affordable time to visit. With 10-14 days, it's possible to experience a combination of cities, beach, and culture in Thailand. Rain in the rainy season tends to come in short intervals, allowing for exploration during the remaining time.
