Exceptional light happens a handful of times a month — the rest is flat, featureless sky. Checking conditions every evening is tedious and easy to forget.
Temperature. Rain chance. Wind speed. None of that tells you whether the sky will produce the kind of light worth driving for. They weren't designed to.
Someone posts a shot at 9pm. You had perfect conditions and didn't know. That's the cost of not having a system watching for you.
Golden hour lasts minutes, not hours. If the alert doesn't arrive early enough to act on, it's worthless. GoldCast notifies you 2 hours before sunset, the night before sunrise.
Choose from any city worldwide. Set the score threshold that matters to you — 60 for reliably good conditions, 75+ for truly exceptional light only.
The system analyzes cloud type and coverage, humidity, horizon clearing, and light angle timing using real weather model data — refreshed every hour.
Sunset alerts arrive 2 hours before golden hour. Sunrise alerts arrive the night before so you can plan. No alert means conditions aren't worth it — silence is information too.
Cirrus clouds at altitude scatter warm light across the sky. The sweet spot is 20–80%. Too little means a featureless sky. Too much blocks everything.
Low cloud near the horizon blocks the sun at the exact moment it produces the warmest light. We penalise this heavily — it's the most common cause of a missed sunset.
Low humidity means cleaner air and more saturated color. High humidity washes out tones. We measure both humidity and aerosol density.
Residual cloud texture after a cleared storm system often produces the most dramatic light of the month. The system detects this pattern specifically.
Golden hour duration and sun angle vary significantly by latitude and season. GoldCast calculates the precise window for your location and date.
An estimate of how many degrees above the horizon color will reach, derived from high cloud coverage. A wide spread is the difference between a nice shot and an epic one.
Chase dramatic skies without spending every evening refreshing forecast apps. Let the alert tell you when it's worth the drive.
Epic light over an urban skyline is fleeting and unpredictable. An alert 2 hours out gives you exactly enough time to get in position.
Know whether conditions at your destination are worth planning a golden hour session around before you even arrive.
You can't check conditions every day. The alert does the monitoring for you — you only hear about it when it actually matters.
Exceptional golden hour content is the difference between a good post and a viral one. Stop leaving it to chance.
