Osoyoos State Park, located east of the mountains, receives significantly less rainfall than regions west of the mountains with an average annual precipitation of twelve inches.
Average summer temperatures are 94 degrees maximum and 50 degrees minimum. Because central Washington is landlocked and subject to winter winds, winter temperatures are much colder than those in western Washington.
