Caught with 801 Gathering, 640 Perception.

To catch this fish, you must first catch a High Quality http://xivdb.com/item/12753/sky+faerie. It has a relatively fast hook time. If using http://xivdb.com/action/4102/patience, you will need to use http://xivdb.com/action/4179/precision+hookset. Then use http://xivdb.com/action/297/mooch to snag the Basking Shark. It's a pretty standard wait time for a legendary fish, with the normal legendary fish tug. http://xivdb.com/action/4103/powerful+hookset should be the one to use if necessary, although I was able to catch this fish without Patience on, so I cannot confirm for sure.

The specific weather transition window is quite rare, so use an outside source for proper weather tracking such as http://www.garlandtools.org/ffxivfisher/
