Early this morning, a special event started on Final Fantasy XIV: A Realm Reborn in celebration of summer. The Moonfire Faire pits you against vicious bombs in a hectic FATE near Costa Del Sol in La Noscea. The event is technically level 32 (although I participated at Level 24 as a healer), and your reward for completing it is Wet Bombard Ash. This item can be turned in at special locations in any of the three towns in return for various swimsuit outfits that provide a +1 Fire Resistance per piece (top and bottom). You can find more details on the event on its Lodestone page.
