Jackson Weather Tips

The weather in Jackson during the summer time is more predictable than during the winter. During the summer, we typically get afternoon thunderstorms and cloudy afternoon weather. As the sky begins to get dark and the temperature begins to drop the clouds almost always dissipate, leaving incredibly clear skies for stargazing. Even if it’s still cloudy at 9pm there is a very good chance that by 10pm the skies will be perfectly clear. In the winter, the weather is less predictable. We get about 70% of our annual precipitation in the form of snow. The storms will come in when they will.

Despite a certain level of predictability, there is really no way to know what the weather will be more than a few hours before the start time of your program. We make all weather decisions at 7pm. We’ll make the best determination on whether we should run your program or not based on as much data as possible. We want you to have a great time with us so we won’t send you out there unless we think it’s going to be worth your time and money. We do not allow guests to re-book for weather before that deadline. Thanks for your patience and understanding.

Standard Weather Forecast is run by long-time local meteorologist, Jim Woodmencey. This will give you a general idea of tonight’s conditions, frequently providing more accuracy than standard national weather sites.

Cloud Cover is a much more detailed forecast of cloud cover for all you stargazing aficionados. It shows hourly cloud cover, transparency, and seeing conditions.

How to Read Clear Dark Sky

The hours of the next few days are listed across the top in different colors for each day.

= Cloudy

= Clear

Moon Phase will show you the current phase of the Moon. The phase of the Moon has a big effect on the overall brightness of the sky. When the Moon is new, the sky is really dark. When the Moon is full, the sky is much brighter; deep space objects and the Milky Way are much harder to see when the Moon is full.

Air Quality will show you current air quality conditions. Particularly in late summer prevailing winds can blow smoke into Jackson Hole. Although the smoke is much more transparent at night when it is not refracting sunlight it does make some of the distant, faint objects in the sky appear somewhat fainter.

Northern Lights is a website that displays an entire forecast just for the northern lights. At its simplest, the Kp-index in the upper left-hand corner of the page on the website needs to be higher than a 5 or 6 to have any chance of seeing Northern Lights in Jackson Hole, WY.
