How Weekend Forecasts Work

Every Wednesday, NoGo pulls weather forecasts, air quality projections, and crowding estimates for 500+ Sierra Nevada locations. Each location gets a NoGo Score from 0 to 100, where lower is better. Scores combine temperature comfort, wind speed, precipitation, EPA AQI, and expected crowds.

Forecasts compare locations within and across corridors to find the best spots for the upcoming weekend. They name specific trailheads, lakes, and viewpoints, not just regions, so you know exactly where to go and what to avoid.

Published every Thursday. If conditions shift dramatically, forecasts can be updated through Sunday.
