A generic read is not your go/no-go
"Mount Rainier is NO-GO" uses a standard day-hiking profile. Whether you should go depends on your activity (a summit scramble reads differently than a valley stroll), your fitness, and your own limits: the wind, heat, cold, and air-quality numbers that mean stop for you. GoNoGo Weather scores Mount Rainier's live conditions against your own limits and gives you one straight answer: GO, CAUTION, or NO-GO.

What drives an outdoor go/no-go
Wind (sustained and gusts, worst on exposed ridges and summits). Heat and cold (apparent temperature and wind chill drive heat exhaustion and hypothermia risk). Lightning (thunderstorms above treeline are a turn-back read). Air quality and UV (wildfire smoke and high UV matter more the harder you work and the longer you are out). Daylight (running out of light is how a fine day goes wrong). These are read live and refresh through the day.
