  1. The quarter from which the average of the 5 windiest days and max wind speed values were derived was based on the months of the warmest quarter (i.e. PwarmQ). Values for the average of the 5 windiest days and max wind speed are for the windiest time of day (consistently 20 h00), with the exception of Diaz Point (14 h00).
