Penmarch is the southwest-most township of
Pays Bigouden, at the southern end of the Bay of Audierne. It is part of the
canton of Pont-l'Abbé, and of the
arrondissement of Quimper. The territory of the town (16.39 km2) is particularly flat; its altitude ranges from -1 to 23 m
amsl. There are many marshy lagoons, some of which have been drained and filled, especially in St. Guénolé to save space or habitat for the installation of local handicrafts. The municipality consists of four villages: • Penmarch-Bourg, formerly known as the Tréoultré; • Saint-Guénolé (main fishing port); • Kerity (fishing port side moving towards the hosting of the craft); • Saint-Pierre (port for very small craft). Many islands or reefs of very variable dimensions punctuate the coast of Penmarch; the most important are the Étocs islets south of Kerity, and the island of Saint-Nonna west of Saint-Pierre. The port of Saint-Guénolé has a pass opening due west, thought to be dangerous in rough weather. It is protected by two granite peninsulas: Krugen in the South, and Conq in the northwest. Krugen is connected to the mainland by a sandy isthmus. Conq is connected to the shore by an artificial embankment itself protected by concrete blocks to better break the flood wave. The rocky granite coast (called "savage coast" in Saint-Guénolé) is interspersed with several beaches: • North, the beach of Pors Carn-which extends to the tip of the torch (joint Plomeur); • West, the beach of Joy; • South, the beach Steir Kerity which begins at and continues through Guilvinec.
Climate Penmarch has a climate bordering between
Mediterranean (
Köppen Csb) and
oceanic (
Cfb). It is heavily moderated by the
Atlantic Ocean and the
Gulf Stream influence, resulting in cool summers and very mild winters for the latitude as seasonal differences are low. ==History==
