Rates how visually interesting the clouds are - distinguishing dramatic formations from boring flat overcast. High scores indicate structured clouds with good light transmission.
High scores (70+) indicate interesting cloud formations - convective development, ice crystals, or dramatic layer structure. Low scores indicate flat, boring overcast.
Cloud Texture Score quantifies the visual interest and structure of cloud formations, distinguishing dramatic, textured clouds from flat, featureless overcast. The algorithm evaluates cloud cover at multiple altitudes, solar radiation transmission, atmospheric instability indicators (CAPE, lifted index, omega), and ice fraction to identify clouds with defined edges, varied patterns, and three-dimensional structure.
High scores indicate photogenic clouds with texture and light transmission—ideal for adding visual interest to landscape photography.
Find cloud detail with enough shape to carry the frame or support a wide landscape.
Use texture signals when a scene needs sky interest but not necessarily storm drama.
Inspect total cloud coverage as one of the forecast signals behind Cloud Texture Score.
Inspect low clouds as one of the forecast signals behind Cloud Texture Score.
Inspect mid-level clouds as one of the forecast signals behind Cloud Texture Score.
Inspect high clouds as one of the forecast signals behind Cloud Texture Score.
Inspect solar radiation as one of the forecast signals behind Cloud Texture Score.
Cloud Texture Score is PhotoWeather's Pro-tier metric for forecasting visually interesting, textured cloud formations, designed for landscape and travel photographers who want clouds that enhance their images rather than create dull, flat skies. Not all clouds are photogenic—flat stratus layers create boring gray overcast that adds no visual interest, whereas cumulus formations with defined edges, varied heights, and dramatic shapes transform an ordinary landscape into a compelling composition. The challenge is predicting when clouds will have structure and texture versus when they'll produce featureless gray.
PhotoWeather's algorithm analyzes cloud characteristics to forecast texture and visual interest. Cloud cover at low, mid, and high levels is examined to identify layered setups where clouds at different altitudes create depth and variation, rather than uniform overcast. Atmospheric instability indicators like CAPE (Convective Available Potential Energy), lifted index, and vertical motion (omega) predict convective cloud development—unstable conditions favor cumulus and cumulonimbus with vertical structure, defined edges, and three-dimensional forms, whereas stable conditions produce flat stratus. Ice fraction in mid-level clouds indicates cloud composition and structure—ice crystal clouds like cirrus have feathery textures, whereas water droplet clouds can be more uniform. Solar radiation transmission is analyzed to determine if clouds allow some light to pass through, creating contrast and illumination patterns that emphasize texture.
Scores above 75% indicate excellent cloud texture with structured formations, varied patterns, and good light interaction—clouds that will add drama and visual interest to landscape images. Photographers typically set thresholds of 70-75% to catch days when clouds will enhance compositions rather than create flat, lifeless skies. This derived field is essential for landscape photographers who understand that the right clouds can make or break an image, providing a forecast that distinguishes between photogenic cloud structure and mundane overcast.
In PhotoWeather, Cloud Texture Score is shown from 0.0% to 100.0%. Use the guide above to choose a narrower range for your subject, season, and location.
Cloud Texture Score combines forecast signals such as Total Cloud Coverage, Low Clouds, Mid-Level Clouds, High Clouds, Solar Radiation 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.
Atmospheric suitability for golden hour photography across extended time window around golden hour periods
Cloud formation suitability for golden hour photography across extended time window around golden hour periods

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.
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)
