The Problem
📸
Most sunsets are unremarkable.

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.

📱
Weather apps aren't built for photographers.

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.

😩
You find out it was incredible after it happened.

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.

Great light doesn't wait.

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.

How It Works
01Step
Select your city and a minimum score threshold.

Choose from any city worldwide. Set the score threshold that matters to you — 60 for reliably good conditions, 75+ for truly exceptional light only.

02Step
GoldCast monitors atmospheric conditions twice daily.

The system analyzes cloud type and coverage, humidity, horizon clearing, and light angle timing using real weather model data — refreshed every hour.

03Step
You receive an email when conditions cross your threshold.

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.

What GoldCast Analyzes
Variable 01
High Cloud Cover

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.

Variable 02
Horizon Clearing

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.

Variable 03
Humidity & Air Clarity

Low humidity means cleaner air and more saturated color. High humidity washes out tones. We measure both humidity and aerosol density.

Variable 04
Post-Storm Clearing

Residual cloud texture after a cleared storm system often produces the most dramatic light of the month. The system detects this pattern specifically.

Variable 05
Light Angle Timing

Golden hour duration and sun angle vary significantly by latitude and season. GoldCast calculates the precise window for your location and date.

Variable 06
Color Spread Estimate

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.

Who It's For
🏔
Landscape Photographers

Chase dramatic skies without spending every evening refreshing forecast apps. Let the alert tell you when it's worth the drive.

🏙
City Skyline Shooters

Epic light over an urban skyline is fleeting and unpredictable. An alert 2 hours out gives you exactly enough time to get in position.

✈️
Travel Photographers

Know whether conditions at your destination are worth planning a golden hour session around before you even arrive.

💼
Busy Professionals

You can't check conditions every day. The alert does the monitoring for you — you only hear about it when it actually matters.

📲
Content Creators

Exceptional golden hour content is the difference between a good post and a viral one. Stop leaving it to chance.

🌄
Golden Hour Enthusiasts

You appreciate the ritual of catching great light. This tool exists so you catch more of it with less effort.

The Science Behind It
Built on atmospheric science, not guesswork.

GoldCast scoring is derived from atmospheric optics principles — cloud type behavior at altitude, aerosol scattering, humidity effects on color saturation, and historical sky pattern analysis. Forecasts are powered by Open-Meteo weather model data, refreshed hourly. The result is a single score that reflects what a photographer actually needs to know: is this sky worth going outside for?
