How to use these numbers

Monthly averages describe the month as a whole, not your specific day. The gap between the high and the low decides what you pack more than the high alone, and the number of rainy days matters more than rainfall volume when you are planning a long walk or an open-air site. If your schedule depends on outdoor activity, put the open-air stops early in the day and keep one indoor place in reserve for any day the weather turns.
