Welcome to my Mount Rainier Weather and Forecast page. I've created this page because I am curious about mountain weather and also enjoy climbing mountains. This page has links to the most applicable official National Weather Service forecasts as well as other resources and products. I hope you find this page useful.

On average, about 10,000 people climb on Mount Rainier each year, but less than half reach the top. More than 50 people have died on Mount Rainier in the past, usually due to falls, avalanches, or exposure. The best way to stay safe on Mount Rainier is to be knowledgeable about the weather, route, and do not exceed your abilities. Proper training and equipment is essential on all routes to the summit. Check with a ranger at any of the ranger stations in the park for current trail and route conditions. Backcountry, climbing, and overnight regulations may apply.
About the experimental gridpoint forecasts. Recent advances in computer technology have made it possible to give forecasts valid for specific localized areas like mountain ridge tops, specific valleys, etc. This is made possible because the NWS forecast data is now entered into a high resolution nation-wide grid. The forecasts below are for grid points on or near Mount Rainier. Although this information is very specific, remember that it is still subject to uncertainty. The weather can be very different on one side of the mountain from the another side.
About the experimental graphical forecasts. The forecast for the entire region including expected snowfall, minimum and maximum temperatures, wind, and other elements can be easily seen from the graphical grid forecasts. This is very useful for seeing fronts and other changes coming in, and will help in determining how the weather could change during your expedition.
To find out what the forecasters were thinking when they made the forecast, read the Area Forecast Discussion (AFD). These are technical discussions on the factors that forecasters feel are important for the current forecast cycle.
Want even more information? Numerous models and upper air data are available at the UCAR-RAP Weather Pages.
