MT RAINIER pretty much makes it's own weather, and because it stands in the path of prevailing moisture laden marine winds, its southern slopes get some world breaking snow fall, and Paradise Inn (a three story lodge) is frequently buried to the tops of its chimneys in snow. Due to the heavy snowfall on the slopes of Rainier, the mountain sports 26 major glaciers. The climbing weather on Mt Rainier is mostly rainy and cold throughout most of the year. This is because the Pacific Ocean produces plenty of moisture. Add to this, the latitude and elevation of the mountain, and you end up with plenty of rain, snow, and frigid conditions that can pop up at anytime of the year.
The best time to climb Mt Rainier is during the months of July and August, when conditions become warmer and drier. But as mentioned above, Rainier makes its own weather and you could find yourself in a white out along with freezing conditions at anytime during the course of the year. So best to get the most current weather report before setting out on any adventure.
