What the Photography Score Actually Means
A breakdown of how OwlPlot calculates that 0-100 number and why a score of 65 might still be worth shooting.
The Photography Score is the first thing you see when you open OwlPlot. Here's how it actually works.
The Inputs
The score combines four weather factors:
Cloud Cover (40% weight) — The biggest factor. Clear skies score high. Overcast scores low. Partly cloudy lands in the
middle.
Precipitation (25% weight) — Any rain or snow drops the score significantly. Light drizzle hurts less than heavy rain.
Visibility (20% weight) — Measured in kilometers/miles. Haze, fog, and humidity reduce visibility. Crystal clear days score high.
Wind Speed (15% weight) — High wind makes tripod work harder and long exposures shakier. Calm conditions score better.
The Scale
- 80-100: Exceptional conditions. Don't miss this.
- 60-79: Good conditions. Worth going out.
- 40-59: Okay conditions. Might work depending on what you're shooting.
- 20-39: Challenging conditions. Only if you're specifically after moody/dramatic shots.
- 0-19: Stay home or embrace the chaos.
Why 65 Might Be Perfect
Here's the thing: the score optimizes for "ideal" conditions, but ideal isn't always what you want.
A score of 65 with some high clouds might give you a better sunset than a score of 90 with completely clear skies.
Those clouds catch the light.
A score of 45 with fog might be exactly what you need for a moody forest shot.
Use the score as a starting point, not a final verdict. Check what's lowering the score (cloud cover vs. wind vs. visibility) and decide if that actually matters for your shot.
Time of Day Matters
The score doesn't account for lighting conditions — that's what the sun/moon times are for. A score of 85 at noon means clear skies, but noon light is harsh and unflattering for most photography.
The same 85 during golden hour? Now we're talking.
Combine the Photography Score with the timing information. High score + golden hour = get out there.
What It Doesn't Measure
Some things the score can't capture:
- Air quality — Smoke, smog, pollution haze
- Interesting cloud formations — Dramatic clouds can make a shot
- Your specific creative vision — Maybe you want rain
The score is a filter for "good weather for outdoor photography" in general terms. Your creative goals might differ, and that's fine.
My Rule of Thumb
I check OwlPlot every morning. If the score is above 70 and golden hour timing works with my schedule, I start thinking about where to shoot. Below 50, I don't stress about missing the evening light.
Between 50-70? I check what's affecting the score and make a judgment call.
