On the East coast, definitely.. man made snow/ ice and corn, your base will go white in a day or two.. but like WasatchMan said.
Some wax every other day, some every week, some once a month, some never do.
If you want to keep you base nice and slick on the hill wax it.. if you don't mind a bit of drag and a decrease in speed then don't bother waxing it as often.
PS. If you're going to buy a tuning kit.. don't get suckered into paying a high dollar for a "waxing" iron.. any iron will do.. travel irons work great. Pick one up at a yard sale and you'll be set.
awesome advice on the iron thank you.... not too worried about the drag or the decrease in speed.... more worried about maintaining my board (so that it doesnt get damaged) so that it will last me a while
