Oh, and it's also the time that Winter Squid turns into Summer Bass.
Fishing up both Winter Squid and Summer Bass is a requirement of The Oceanographer achievement. Much like the world event and holiday achievements, though, you need a certain time of year to be able to complete The Oceanographer. Winter Squid is fishable from September 23rd to March 20th, and Summer Bass from March 21st to September 22nd. Both can be found in normal waters (no schools or pools needed) in Sunken Temple, Feralas, The Cape of Stranglethorn, Badlands, Tanaris, Blasted Lands, and Swamp of Sorrows. Swamp of Sorrows appears to have the highest drop rate for the squid, and Blasted Lands is the best for bass. If you're a squid away from The Oceanographer, now's the time to cast your line! This has been a friendly reminder from your neighborhood WoW Insider columnists. Happy fishing!
