Sunset Forecasts
The sunrise and sunset forecasts are the core features of Sunsethue. The quality of a sunrise or sunset tries to describe how good the sunset experience will be. Quality scores range from 0% to 100%, the higher the score the better the sunset. A high-quality sunset is vivid, colourful, has a significant duration and is overall spectacular. The quality metric can inform you about the upcoming sunset at a glance.
The Sunsethue Model
Sunsethue uses a ray-based model to make the sunrise and sunset quality predictions and cloud cover metric. Based on the latest weather model data, an algorithm calculates if light can reach the clouds during sunrise or sunset for every location in the world. This approach results in generally accurate forecasts if the weather forecasts are accurate.
Worldwide Coverage
The Sunsethue model makes quality predictions for every location worldwide. You can use Sunsethue anywhere at any time to access the latest sunrise and sunset forecasts for today and the upcoming days for your desired location. With a Sunsethue account, you can save and monitor your favourite locations.
Golden Hour
Golden hour and blue hour timings are available alongside the actual time of sunrise or sunset. Combine the time of golden hour with the forecasted quality of the sunset to determine when to go out and experience amazing sunsets.

Frequently Asked Questions
Sunsethue uses a ray-based approach to determine if a sunrise or sunset will be good. The algorithm determines if light can be reflected from the clouds that are visible for a certain location. If a lot of light of the setting sun can be reflected, this results in a high quality score. This is the general intuition, the actual workings are a bit more complex than this.
The sunrise or sunset quality score is a value between 0% and 100% indicating how good the sunrise or sunset is forecasted to be. The score is a summary of multiple aspects of a sunrise or sunset: the colors, duration of the colors, expanse of the colors, etc. In short, it tries to capture how spectacular the sunrise or sunset is forecasted to be in a single number.

A lot of information regarding the upcoming sunrises and sunsets are available on Sunsethue. The web app is centered around the sunrise or sunset quality metric, but you can also access information about the cloud cover during sunrise or sunset, the amount of clouds at the horizon and the uncertainty. Of course, you can also access information regarding the time of sunrise and sunset, and about the blue hour and golden hour.
The algorithm uses weather data (mainly cloud cover data) as input. Weather forecasts, and especially cloud cover forecasts, can be wrong sometimes. Small changes in this input may result in a vastly different sunrise or sunset quality. The forecasts generally get more certain as they become closer in time, so check back in regularly for the best forecasts. You can also use the uncertainty metric to assess the level of uncertainty for a given sunrise or sunset.
The Sunsethue website is fully free to use for anyone, no account is needed to access the forecasts. The general quality forecasts for the upcoming days will remain free forever, some more advanced metrics may be moved to a premium version later on. I also chose to not use any ads on Sunsethue to improve the user experience, and because I really dislike ads myself. Currently, the only paid service on Sunsethue are the Premium Alerts.
When the upcoming sunrise or sunset is forecasted to be above the threshold you set, you will receive an email to alert you of a possibly good sunrise or sunset. This way you never have to miss a good sunset again. You can choose for which events to receive an alert by entering your preferences when signing up for alerts. The settings in the free version of alerts are restricted to limit expenses. For the full experience, you can sign up for the Premium Alerts.
