Sky report
Read the cloud deck before you read a brochure. The summit is a weather fact, not a promise.
The deck
Stand in town and look at the ridge line. If the rock is sharp against the sky, the summit is open. If the ridge dissolves into grey, you will stand in cloud. That is the whole observation.
Chinook
A chinook is a warm west wind that piles a hard arch of cloud and leaves a bright slot underneath. The air feels soft and the snow shrinks. Visibility can be excellent under the arch and useless inside the cloud itself. Do not confuse a pretty arch with a clear summit.
Season
Winter mornings are the cleanest, and the coldest. Spring brings more decks that sit on the ridge until noon. Summer afternoons build cumulus that can cap the summit by mid-day even when breakfast was blue. Autumn is the steadiest clear stretch I keep in the log.
Hour
Go early. The deck often lifts or drops with the sun, and a late slot is a gamble. If the summit was buried at nine, do not assume it will be open at four.
