Asia-based Agoda.com, a member of The Priceline Group, released the results of their latest Travel Smart study this week. The study focused on the fluctuation of hotel prices in 25 international destinations over the course of a year in order to predict the best times to travel based on room rates.

The study revealed room rates tend to be below average during the first two weeks of the new year and rates are often highest during the months of September and October. While these findings were consistent across the board, there were obvious differences dependent upon location. Rooms in Europe are often as much as 20 percent below average cost during March, while price dips in New York and Australia are seen in July. Heading to Barcelona? Agoda says you’ll want to go in January, when rooms are almost half off the average price. The one region with relatively average prices all year round includes their popular Asian destinations like Hong Kong and Phuket.

Data collected from the study is being used to create a user-friendly trip-planning calendar to assist potential Agoda users in finding the best room rates possible.

Agoda.com is an online accommodation reservations service, similar to Priceline and Hotwire. They feature more than 750,000 hotels worldwide, with a focus on business-friendly and luxury properties.
