September leads the rain charts: longer, more frequent downpours and the roughest west-coast seas of the year. It's the bottom of the price curve — ideal for spa-food-and-workspace stays or locking a long-term lease. Swim at sheltered southeast bays; watch the Vegetarian Festival's dramatic processions in Town late month.
