Fiery Red Sky Potential
Predicts the chance of vivid red, orange, and pink sunrise or sunset color. Best when the sun has a clear opening near the horizon, some clouds are ready to catch the light, and low clouds are not blocking the show.
What is Fiery Red Sky Potential?
Technical detailsFiery Red Sky Potential helps you find the sunrises and sunsets most likely to light up with rich reds, oranges, and pinks. The best setups usually have a clear opening near the sun, some mid or high clouds to catch the light, and not too much low cloud blocking the view. Cleaner air can help the color pop, while smoke or a low cloud deck often turns a promising sky into a dull one.

How to use this conditionThe best fiery skies usually need a clear gap near the sun, some mid or high clouds to catch the light, and not too much low cloud blocking the view. Smoke often dulls the color. Combine with 'solar_elevation: [-7, 3]' for a practical timing window.
Fiery Red Sky Potential in photography
In depthFiery Red Sky Potential is PhotoWeather's forecast for colorful sunrises and sunsets. It highlights the times when the sky is most likely to glow with strong reds, oranges, and pinks, so you can focus on the hours that are actually worth chasing with a camera.
The best fiery skies usually happen when the sun has a clear gap near the horizon and there are enough mid or high clouds to catch the light. Too many low clouds can block the color completely, while a sky with no clouds at all often gives you less drama than you hoped for. The sweet spot is usually a mostly open horizon with some good cloud structure above it.
This score is made for photographers who want better correlation with real colorful skies, not just generic golden hour timing. Higher scores mean the forecast looks much more like the kind of sunrise or sunset that can really light up. Lower scores usually mean the color will be blocked, muted, or simply never develop.

What values are typical for Fiery Red Sky Potential?
Fiery Red Sky Potential typically ranges from 0.0% to 100.0%. PhotoWeather monitors these values to help you identify ideal conditions for your photography goals.
How is Fiery Red Sky Potential calculated?
Fiery Red Sky Potential is an advanced derived condition calculated from multiple weather parameters including Low Clouds, Mid-Level Clouds, High Clouds, Visibility, Aerosol Optical Depth (550nm). PhotoWeather's algorithms analyze these factors to provide a single, easy-to-understand score for this photography opportunity.

Value rangeRelated fields
Similar weather conditionsAurora Quality
Combines aurora activity with viewing conditions (darkness, cloud cover, visibility) to provide photography-ready aurora quality scores. Aurora activity is OVATION-aware from the compute step.
Blue Hour Quality
Evaluates atmospheric conditions for blue hour photography quality. Scores sky clarity, cloud type suitability (high thin clouds ideal), visibility, and calm conditions.
Fog Probability
How likely fog is to form. High scores mean misty, atmospheric conditions for moody landscape and sunrise photography.
Golden Hour Potential
Atmospheric suitability for golden hour photography across extended time window around golden hour periods
Golden Clouds Potential
Cloud formation suitability for golden hour photography across extended time window around golden hour periods
Cloud Drama Score
Analysis of cloud formations and atmospheric conditions for dramatic sky photography
Storm Intensity
Storm intensity analysis combining precipitation, wind conditions, atmospheric pressure, visibility, GFS simulated radar reflectivity, and wind shear for enhanced storm organization detection.
Frost Probability
Frost formation probability combining temperature, dewpoint spread, cloud cover, and wind analysis
Rainbow Probability
Probability of visible rainbow formation based on solar geometry and precipitation patterns
Coastal Drama Score
Analysis of coastal conditions combining wave dynamics, atmospheric conditions, and lighting for dramatic seascape photography. Evaluates wave height, swell patterns, spray potential, and atmospheric drama factors.
Atmospheric Clarity Score
Comprehensive atmospheric clarity analysis for landscape and astrophotography using CAMS aerosol optical depth, particle composition (dust, smoke, sea salt), particle size distribution (Ångström exponent), and visibility conditions.
Light Breakthrough Potential
Likelihood of sun breaking through clouds creating dramatic rays and dappled light patterns. Best with partial cloud cover (40-70%) and some sunshine reaching the surface.
Soft Light Index
Quality of diffused light for portrait and product photography. High scores indicate soft, even lighting that minimizes harsh shadows - the 'giant softbox' effect.
Cloud Texture Score
Rates how visually interesting the clouds are - distinguishing dramatic formations from boring flat overcast. High scores indicate structured clouds with good light transmission.
Overcast Flatness
How flat and boring the overcast is. HIGH scores indicate uniform gray sky with no breaks or texture - generally unfavorable for most photography. LOW scores indicate breaks, texture, or clearing.
Low Clouds
Cloud coverage below 2km altitude
Mid-Level Clouds
Cloud coverage between 2-6km altitude
High Clouds
Cloud coverage above 6km altitude (cirrus)
Aerosol Optical Depth (550nm)
Total aerosol optical depth at 550nm. Lower values indicate clearer skies and more vivid colours.
Solar Elevation
Sun's angle above horizon (0° = horizon, 90° = zenith)
