LucidSky

Most weather apps give you a single number and call it a forecast. LucidSky shows you where forecasts are confident and where they're not, built on National Weather Service (NWS) data with ECMWF, GFS, HRRR, and ICON model comparison.

A free Dark Sky alternative for people who want to understand the weather, not just glance at it.

See what meteorologists actually see.

Weather forecasts are inherently uncertain, but most apps hide that behind a single number. LucidSky doesn't. Choose Honest Mode to see confidence ranges around every prediction, or stick with Classic Mode for a clean, traditional experience. Same data, more transparency.

Looking for a Dark Sky, AccuWeather, or Apple Weather alternative? LucidSky gives you NWS-sourced forecasts, animated precipitation radar, and multi-model ensemble comparison without subscriptions, ads, or data selling.

WEATHER MODELS, EXPLAINED

Different weather models predict different outcomes. When they agree, you can plan with confidence. When they disagree, you'll know to have a backup plan. LucidSky's multi-model ensemble view puts forecast uncertainty in your hands instead of hiding it behind a single number.
