The often intense Perth heat is famously eased in the afternoon by the Fremantle Doctor, a breeze which sweeps in along the Swan River.
The reason for the obliquely-onshore sea breeze system in Perth may be attributed to the interaction between the sea breeze and the geostrophic winds associated with the synoptic weather patterns. The Perth sea breeze system in sensu stricto is southwesterly due to a combination of pressure gradient flow (owing to differential heating) and the Coriolis force (Kepert and Smith, 1992). The Coriolis force has no influence on the wind direction at the start of the sea breeze, but may induce a small anti-clockwise shift in the wind direction of about 200 during the sea breeze.
