What's the Current Weather in Rocky Mountain National Park?

What to expect during the spring season

Spring in the Rocky Mountains can often look like winter. While we may have warm sunny days, we also get our biggest snowfalls of the year during the spring season from March through May. While some days may have very nice weather in Estes Park or Grand Lake, it is likely that you will find more wintery conditions higher up in the mountains, where the snow has yet to melt.

Current Conditions

While the overall size of Rocky Mountain National Park may be relatively small, the weather can vary drastically from place to place, especially as you change altitude. It is therefore wise to look at several forecasts to get an idea of what to expect. Be sure to not only look at the temperature and the chance of storms, but also the expected wind speed as that can impact how cold it feels. The winds can at times be so strong (+40mph) as to make hiking dangerous and topple trees. While these forecasts by the National Weather Service are very helpful, it is important to note that accurately predicting mountain weather is extremely difficult, so always prepare for unexpected changes in the weather.

Dangerous Streams

During the spring and early summer the melting snow leads to fast running streams in Rocky Mountain National Park. These are much more powerful and dangerous than they look. During this time of year stay away from streams, do not try to cross them without a bridge, and keep children away from them.

Avalanche Awareness

From mid-October through mid-June anyone hiking, skiing, or snowshoeing in the mountains should be aware of the potential for avalanches to occur. A good rule of thumb is to avoid being on or immediately below slopes that have an angle of 35-45 degrees and to know the current avalanche forecast before you head out.

Here's a good primer on avalanche safety by the Colorado Avalanche Information Center.

Smoke and Air Quality

With the growing number of wildfires in the western North America, we've had to adapt to much more smoke in the air. While Colorado skies have historically been crisp and clear, more recently they have been very hazy as smoke rolls in from fires far and near. Fires in other parts of Colorado, in Arizona, Montana, Canada or any of the surrounding areas can produce smoke that fills our skies. This can dramatically impact the views of the surrounding peaks and even result in air that can at times be unhealthy to breathe. Here are some tools that you can use to evaluate the impact of smoke on this area. Also, check out the webcams as they can give you an idea of the current smoke in the air.
