Further Analysis
The Fremantle Doctor is strongest in December and January, when the temperature differential between the land and ocean is greatest. In February and March the breeze is not as strong, because the ocean temperature is a bit warmer. Though October and November are not as warm, the ocean temperature is cooler resulting in the sea breeze in these months.
Other months have a weak or non-existent Fremantle Doctor. In the winter months, the land temperature is usually cooler than the ocean temperature, and this sometimes results in the weaker land breeze in the early morning.
When the Fremantle Doctor first arrives it is from the west-south-west (WSW) direction. Later when it is at maximum strength, the direction is usually from the southwest or south-south-west. By the early evening, the direction is from the south. This change in wind direction is due to the Coriolis Effect. Other factors, like the prevailing wind of a particular day, can also have an effect on the direction.
A wind rose showing the different wind directions for Perth can be found at the Bureau of Meteorology's website.

Famous quotes containing the word analysis:
“Analysis as an instrument of enlightenment and civilization is good, in so far as it shatters absurd convictions, acts as a solvent upon natural prejudices, and undermines authority; good, in other words, in that it sets free, refines, humanizes, makes slaves ripe for freedom. But it is bad, very bad, in so far as it stands in the way of action, cannot shape the vital forces, maims life at its roots. Analysis can be a very unappetizing affair, as much so as death.”
—Thomas Mann (1875–1955)
“... the big courageous acts of life are those one never hears of and only suspects from having been through like experience. It takes real courage to do battle in the unspectacular task. We always listen for the applause of our co-workers. He is courageous who plods on, unlettered and unknown.... In the last analysis it is this courage, developing between man and his limitations, that brings success.”
—Alice Foote MacDougall (1867–1945)
