Atmospheric suitability for golden hour photography across extended time window around golden hour periods
Evaluates atmospheric conditions for golden hour photography regardless of exact timing. Combine with 'golden_hour: any' for clean event timing.
Use these as planning patterns, then adjust thresholds for your subject, season, and location.
The score turns a clock-based light window into a weather-aware planning cue.
Golden hour timing with enough clarity and cloud structure for light to reach the scene
Relying on golden hour time alone when low cloud, haze, or precipitation blocks the light
Good alerts should reflect both timing and atmosphere, not just the position of the sun.
Combine the score with your location and subject so alerts fire for usable warm light
Broad alerts that trigger every morning and evening regardless of sky conditions
Golden Hour Potential evaluates atmospheric conditions for high-quality golden hour light regardless of exact solar timing. The score assesses cloud cover at different altitudes (some clouds enhance the scene, too many obscure it), visibility for color saturation, wind for stable shooting conditions, and humidity for atmospheric clarity. This metric focuses on whether the atmosphere will support beautiful golden light when the sun reaches the right elevation.
Separate ordinary golden-hour timing from weather that may actually let warm light reach the subject.
Keep routine sunrise and sunset alerts from firing when the sky is unlikely to cooperate.
Inspect total cloud coverage as one of the forecast signals behind Golden Hour Potential.
Inspect low clouds as one of the forecast signals behind Golden Hour Potential.
Inspect mid-level clouds as one of the forecast signals behind Golden Hour Potential.
Inspect high clouds as one of the forecast signals behind Golden Hour Potential.
Inspect visibility as one of the forecast signals behind Golden Hour Potential.
Golden Hour Potential is PhotoWeather's specialized metric for forecasting atmospheric quality during golden hour, designed for photographers who need to know not just when golden hour occurs, but whether weather conditions will allow the signature warm, directional light to shine through. Golden hour—the period shortly after sunrise or before sunset when the sun is low on the horizon—produces soft, warm light that's ideal for portraits, landscapes, and architecture. However, the quality of this light depends heavily on atmospheric conditions that standard weather forecasts don't address.
Clear skies provide clean, warm illumination, but some clouds can actually enhance golden hour by adding texture, color, and drama to the sky. The challenge is predicting the right amount of cloud cover: too many clouds obscure the sun entirely, while the ideal scenario features scattered mid or high clouds that catch golden light without blocking it. PhotoWeather's algorithm evaluates cloud cover at low, mid, and high altitudes, scoring each based on its effect on golden light transmission and sky aesthetics. Visibility is critical for color saturation—haze and pollution dull the warm tones that define golden hour, so higher visibility scores correlate with richer colors. Wind conditions matter for practical photography reasons: calm conditions allow for stable tripod work and smooth water reflections, while gusty winds complicate long exposures and portrait work. Relative humidity affects atmospheric clarity and can introduce haze that softens golden light.
For Plus and Pro users, PhotoWeather enhances accuracy with horizon probe sampling, checking cloud cover and visibility specifically toward the sun to predict conditions along the golden light path. Scores above 80% indicate excellent atmospheric conditions with clear or ideally-clouded skies and good visibility. Photographers typically combine this condition with the boolean golden_hour field for precise timing, using Golden Hour Potential to filter for days when the atmosphere supports beautiful light, then using the time-based filter to catch the exact window. This derived field is essential for photographers planning golden hour shoots, ensuring they chase conditions that deliver the warm, glowing light that makes this time of day legendary.
In PhotoWeather, Golden Hour Potential is shown from 0.0% to 100.0%. Use the guide above to choose a narrower range for your subject, season, and location.
Golden Hour Potential combines forecast signals such as Total Cloud Coverage, Low Clouds, Mid-Level Clouds, High Clouds, Visibility into one photography planning cue. Use it as a shortlist, then check the individual fields before committing to a shoot.
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.
Evaluates atmospheric conditions for blue hour photography quality. Scores sky clarity, cloud type suitability (high thin clouds ideal), visibility, and calm conditions.
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.
How likely fog is to form. High scores mean misty, atmospheric conditions for moody landscape and sunrise photography.
Cloud formation suitability for colorful sunrise and sunset skies around golden hour
Analysis of cloud formations and atmospheric conditions for dramatic sky photography
Storm intensity analysis combining precipitation, wind conditions, atmospheric pressure, visibility, GFS simulated radar reflectivity, and wind shear for enhanced storm organization detection.
Frost formation probability combining temperature, dewpoint spread, cloud cover, and wind analysis
Dew formation probability combining overnight radiative cooling, surface temperature, moisture, and wind analysis
Probability of visible rainbow formation based on solar geometry and precipitation patterns
Analysis of coastal drama combining wave dynamics, wind-driven spray and atmospheric cloud structure for seascape photography.
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.
Scores forecast sky quality for deep-sky, starscape, and nightscape photography using darkness, moon interference, clouds, atmospheric transparency, precipitation risk, and forecast confidence. This is not a Bortle class or site-darkness/light-pollution rating.
Scores Milky Way core / Galactic Center shootability using Galactic Center altitude plus dark, clear, transparent, moon-friendly forecast sky conditions. This is not a generic Milky Way band detector or site-darkness rating.
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.
Quality of diffused light for portrait and product photography. High scores indicate soft, even lighting that minimizes harsh shadows - the 'giant softbox' effect.
Rates how visually interesting the clouds are - distinguishing dramatic formations from boring flat overcast. High scores indicate structured clouds with good light transmission.
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.
Cloud coverage below 2km altitude
Cloud coverage between 2-6km altitude
Cloud coverage above 6km altitude (cirrus)
Sun's angle above horizon (0° = horizon, 90° = zenith)
