A phenomenon common in coastal regions where a pattern of cloud building just inland with clear skies out to sea can divide a major city in two for hours, with one half in constant sunshine and one half in constant shade. First noticed in Plymouth.

Can also refer to fog related microclimates where the coast of, say LA may be under chilly thick fog but a few blocks inland basks in warm sunshine.
Lets walk down the coast a bit first. Its Plymouthed Sun around here!
