Where on Earth is the most windless lake with its own micro climate sea breeze?
Wind Vortex on a Lake: the only thing I can visualize is a Tornado on a Lake.

Examples: Pine Lake tornado, Lake of the prairies Tornado

Technically speaking, a breeze/wind cannot be contained within a Lake, unless the lake is covered by mountain-cliffs or canyons at all sides. Maybe something like Marietas Island's hidden beach or Melissani Cave, but much larger would sustain a self contained breeze.
