Weather on Courses

Weather is. That’s about as much as we can tell you. It’s not “good” or “bad” – it just is, and we work with it depending on the situation we find ourselves in. As a result, our courses and lesson plans adapt to current conditions, trying to make the most of whatever Mother Nature gives us.

On our courses, the equipment list you are sent has been designed to accommodate the most common weather patterns. Sometimes, though, we’ll get an unusual year and see more rain / snow / sun than we expected. While the Boulder area has “normal” weather patterns – cold, snowy winters; hot, dry summers; wet, windy autumns – you never know what you’re going to get. Many of our students have come in July (when it’s typically hottest) to find snow on the ground in the morning.

The key, as always, is flexibility, to plan for the worst weather conditions, hope for the best, and then adapt. Having said that, though, there are some general patterns we can share about weather in the Boulder, Utah area.

Historic Weather Patterns

Traditionally, weather in the Boulder / Escalante area of Southern Utah looks something like this:

April / May – Days are warm in the afternoon (80ºF/27ºC at the highest) and cold at night (38ºF/3ºC). Skies are typically clear, with not much precipitation. The land is just starting to wake up. Students on courses during April/May will enjoy great daytime hiking weather, but evenings will be cool / cold.

June – By June, daytime temperatures can be high (95ºF/35ºC) and nights are moderate (48ºF/9ºC). Trees and other flora are in bloom and afternoon skies are still typically clear. If you don’t mind heat (or pollen), this is a great month for hiking, as June is the driest month of the year.

July – July is typically the hottest month of the year, with average highs reaching 100ºF/38ºC. Evenings often start warm, cooling to a still comfortable 55ºF/13ºC in the early morning hours. Peak hiking season, although afternoon clouds are likely after mid-July, as monsoon season approaches.

August – Monsoon season can bring cooling afternoon rains and, if you’re in the canyons, a concern for flash floods. However, don’t let that stop you from coming – BOSS courses in August are great fun, as flora are in full bloom and there’s plenty to explore on the trail. Average high temperature is 98ºF/36ºC and low is 51ºF/11ºC.

September / October – Autumn in Southern Utah is often spectacular, as aspen groves turn from green to vibrant gold and the landscape prepares for winter. Daytime temperatures average 85ºF/29ºC and 39ºF/4ºC at night, making the early mornings cool again. Monsoon season can sometimes extend into the fall months so, like August, make sure you come with a good poncho. Students who prefer to hike in cooler temperatures often sign up for Field courses in this time of the year, as there’s not as great a challenge from heat-releated issues.
