I've played Tumble Creek many times in May. The turf conditions are still recovering from winter at that time of year - and this has been a very snowy winter in the Cascade Mountains. It's a nice walk for a mountain course with the toughest stretch being the walk from the 18th green to clubhouse. I've played in a wet snow and I've played in near 80-degree weather in May. Count on a 2-3 club wind. Enjoy.
