The Heatwave Party is a seasonal party with a summer theme. It is available to everyone and usually can be found during June to August. This party was not hosted during 2015 and 2016; however, it returned in 2017 on January 5th.
This party appears as a Water Park Den that has been flipped horizontally with the entire layout mirrored. It is decorated with beach-themed items such as the towels sold during previous years, the Seahorse fountain from Bahari Bay, and the beach umbrellas available in the party shop.
This party has three water slides and two pools of water that can be used by all Jammers. There is also a Smoothie Machine where players can make a drink that can be carried around the party. A shop can be found under a striped awning that sells beach related den items.
|Small Beach Towel||150||No|

- The Smoothie Machine could be purchased here for 4,500 Gems at one point.
