Why Cloud Cover Percentage Isn't Enough

A standard weather app showing 40% cloud cover could mean a flat grey sky or a spectacular sunset — the difference is entirely in the cloud altitude, the horizon band, and atmospheric clarity. The variables that determine sunset quality don't appear in any mainstream weather app.

☁️
Cloud Altitude, Not Just Coverage
Low stratus at 2,000 feet blocks all direct light. Mid-level altocumulus at 15,000 feet catches and reflects warm tones across the sky. The same coverage percentage reads completely differently depending on altitude. GoldCast separates cloud cover into low, mid, and high layers.
🌅
The Horizon Band
A clear band near the horizon is the single most important factor for dramatic sunset colour. It allows direct sunlight to travel low through the atmosphere and illuminate cloud above it from below. Cloud sitting at the horizon blocks this entirely. GoldCast factors horizon clarity into its score.
💧
Humidity and Atmospheric Clarity
High humidity diffuses and softens colour. Low humidity after a cold front produces crisper, more saturated tones. Haze from humidity or pollution reduces colour saturation even on technically clear days. GoldCast scores atmospheric clarity alongside cloud conditions.
⏱️
Exact Golden Hour and Blue Hour Timing
No standard weather app tells you when golden hour starts and ends for your location. Duration varies from 20 minutes near the equator to 90+ minutes at high latitudes in winter. GoldCast calculates the precise window for your location and date — not a generic estimate.

Push Alerts When Conditions Look Exceptional

The most common problem for sunset photographers is finding out the evening was spectacular after the fact. GoldCast monitors conditions at your saved locations daily and sends a push alert when the forecast scores above your threshold — giving you time to plan before the window opens, not after it closes.

🔔
GoldCast Push Alerts
Set your location and minimum score once. GoldCast alerts you ahead of high-scoring golden hours at your saved locations. Exclusive to the iOS app — so your phone tells you when to go out, not Instagram the next morning.
Common Questions
What is the best weather app for sunset photography?
LightCast GoldCast. It scores cloud altitude, horizon clarity, atmospheric haze, and humidity together into a single sunset quality score, and calculates the exact golden hour window for your location. Push alerts notify you when conditions look exceptional. Free on the web, alerts in the iOS app.
What makes a sunset good for photography?
Broken mid-level cloud with a clear horizon band, low humidity, and good atmospheric clarity. The best colour often comes 5–20 minutes after the sun sets, not at the moment of sunset. GoldCast scores all of these and marks the post-sunset peak window.
Does LightCast show golden hour timing?
Yes. GoldCast calculates the precise golden hour and blue hour start and end times for any location and date. Duration varies significantly by latitude and season — GoldCast gives you the exact window, not a rough estimate.
Does it work for sunrise too?
Yes. GoldCast scores and times both sunrise and sunset golden hour windows. Sunrise tends to have calmer wind and cleaner air than sunset at the same location — GoldCast scores both so you can decide which is worth getting up early for.
What else does LightCast include?
Six photography weather tools in one app: GoldCast (sunset and golden hour), StarCast (night sky), DroneCast (drone flight), CloudCast (cloud conditions), FogCast (fog prediction), and TriCast (camera calculators). $2.99/month after a 7-day free trial.
