How to read: Each row shows when a condition blocks opportunities. Stronger red means more locations are affected. These are the top 5 conditions preventing matches across the 95-hour forecast.
Rocky Mountains astrophotography forecast for Estes Park, Aspen, and the San Juans, tracking darkness, moonlight, cloud, and atmospheric clarity.
This rule looks for true astronomical night, cloud cover no higher than 20%, visibility of at least 12 km, precipitation probability no higher than 10%, and either Moon illumination no higher than 35% or Moon altitude no higher than 10°. It does not calculate Galactic Centre or Milky Way core altitude; check a sky planner for the subject's position.
This forecast identifies clear, dark intervals for stars above Colorado's high country. Estes Park gives access to lake-and-peak foregrounds near Rocky Mountain National Park, while Aspen, Crested Butte, and the San Juan towns of Telluride, Silverton, and Ouray place distinctive ridgelines beneath the Milky Way.
The Galactic core is most useful from spring through early autumn, but access controls the season: high passes and alpine lakes can remain snowbound into June, and summer afternoons often build thunderstorms that leave residual cloud after sunset. Autumn usually brings drier air, while winter offers long darkness but cold, avalanche exposure, and closed roads.
Elevation can improve transparency, but it also increases wind, hypothermia risk, and altitude illness. Nearby ski areas and resort towns create local light domes, so compositions around Aspen, Vail, and Breckenridge need careful orientation. The forecast does not verify trail, pass, or timed-entry status; confirm access and avoid exposed ridges whenever lightning remains possible.
How this forecast is made
Opportunities are threshold-based signals: PhotoWeather checks whether forecast conditions match the rules for a photography scenario. They are planning guidance, not guarantees. Forecasts can change as new model runs arrive, and confidence generally decreases farther into the forecast horizon, so recheck conditions before travelling.
The weather forecast foundation comes through Open-Meteo , which aggregates models from weather agencies. PhotoWeather applies condition-specific thresholds and derived calculations; not every condition uses every model or data input.
