Who is this for?

Skyfire is designed for the outdoor photographer who wants to capture images in the best possible light - people who appreciate knowing in advance if the sunrise will be worth getting up for at 5 am on a chilly winter morning.

Skyfire is another tool in the photographer's kit which helps plan shoots ahead of time, leading to better images.

Galen Rowell said that all photographs are made from three parts: skill, equipment, and environment. Skyfire lets you master the one element that has always been impossible to predict: the environment.

What's the recipe for great skies?

Time of day, plus cloud cover, plus a clear horizon equals color-filled skies.

  • Time of day means sunrise/sunset, but which day will have cloud cover at those times? 
  • Cloud cover, yes but at what altitude, quality and volume? 
  • Clear sky at the horizon, but in which direction and just how clear?

Using national and regional weather forecasts, Skyfire employs complex algorithms to analyze, interpret, and generate predictions for sky color.

In an easy-to-use interface, the information is displayed as an overlay on a map. The varying colors of the overlay tell you where the color is predicted to be:



Skyfire maps display the forecast for the area directly overhead of the map location.

This is designed to help you plan your photo shoot by allowing you to get to the optimum location ahead of time. In the sunset forecast below, the photographer is in a great position to capture fiery clouds lit from the west by the setting sun. If he/she were on the east side of Denver, the clouds would be back lit instead of front lit:



Here are two examples: a consecutive sunset and sunrise. You can see that the Skyfire forecast for sunset on Sunday March 4 2018 was mostly blue in the Boulder area, meaning largely overcast. The photo shows actual conditions at the time of sunset - not much color in evidence:

The forecast for the following morning was for good color over the Continental Divide to the west of Boulder, but clear skies to the east. Boulder itself was shown as green (50-60% chance of color). The photos below show that things turned out pretty much as predicted: good color over the Divide and clear to the east:

Skies over Boulder were in fact clear, reflecting a level of unavoidable uncertainty in cloud and weather forecasting.

The red band of clouds you see is 26 miles due west from the shooting location. Remember that often, clouds are visible from many miles away. You don't need to be directly under the red area to see fiery skies. High clouds, such as those often seen in winter months, may be visible from 40 or more miles away.

Where do you offer Coverage?

Skyfire currently offers coverage in the continental United States, Southern Canada, and Europe. We are working to expand the service as we continue development to other areas.


What's an Ensemble Forecast?

The Skyfire forecast is an ensemble forecast. It aggregates data from NOAA and the National Weather Service and applies its own post-processing to develop the best forecast possible.  Cloud data is very difficult to predict, as it is a complex process. By using multiple data sources we can increase forecast accuracy.

Below you see what the input/output data looks like on a typical week, with Skyfire output shown in red. Note how the various input forecasts can disagree with one another: sometimes one is forecasting clear skies and another 100% overcast.  We use secondary indicators in the data to determine which is likely to be correct.
