Overall rating
Best window: 8 PM (Excellent · 91/100)
Some conditions data (cloud cover or barometric pressure) was unavailable from the weather service for this day — the rating above reflects only what was available.

Species context
Excellent (86/100) for Walleye: water is estimated at 68°F, inside Walleye's 65-75°F optimal range. Best window: Dusk -- boosts feeding activity by about 40%, one of their peak feeding windows. That hour also overlaps a minor solunar period. Stable pressure modeled flat — no change from this fish's baseline. Calm (0-5 mph) wind modeled about 15% below this fish's baseline.
Water temperature (68°F estimated) is doing the most for this score. The score gives up the most on solunar period — minor period, about 6 points below its best.
Water temperature: 68°F estimated

Optimal range 65-75°F
Well supportedWater temperature governs a cold-blooded fish's metabolism, so it is the largest term in the model (Christie & Regier 1988). The figure is a thermal-lag estimate built from forecast air temperature and the time of year — not a sensor reading, and not this lake's actual measured water.

Light window: Dusk
25 of 25 pts
Boosts feeding activity by about 40%
Well supportedLow-light feeding windows are the strongest timing signal inside a single day. How much each window is worth is this species' own cited response, sourced in its model file, not a generic curve.
Solunar period: Minor period
9 of 15 pts
Not supported by testingPeer-reviewed testing of North American freshwater fisheries found no significant relationship between solunar values, lunar phase or lunar illumination and catch rates (SN Applied Sciences, 2023) — air temperature predicted catch better than any solunar table tested. It is shown because anglers expect it, and it is shown separately so you can discount it. Its weight is under owner review.
Barometric pressure: Stable
9.5 of 10 pts
Modeled flat — no change from this fish's baseline
ContestedThe barometric effect is real to most anglers but small and contested in the literature — several of the species studies cited in this model report null results — so it carries one of the smallest weights here.
Wind: Calm (0-5 mph)
7.1 of 10 pts
Modeled about 15% below this fish's baseline
Moderately supportedWind stacks forage on windward structure, but both the size and the direction of the effect depend on the species and the water, so it carries a modest weight.
Then the whole score is scaled
Season: Summer — ×1.00 (100% of the ungated score)
How catchable Walleye are at this point in the year. This scales the whole score rather than competing with the factors above — a fish that is dormant this time of year cannot score well no matter how good the hour looks.
Weather front: No clear front — ×1.00 (100% of the ungated score)
A multi-hour frontal pattern read from the day's forecast trajectory. No front is classified today, so this changes nothing and the single-reading pressure factor above does its normal job.
Those five factors add up to 90.6 of 100 points, and the two multipliers above take that to 91. The weights are v1 tuning constants under owner review — they are shown here rather than hidden so you can weigh them against your own judgement.
What this score does not know
Conditions read from the National Weather Service as of Jul 28, 2026 at 8:18 PM CDT. Solunar periods and sun/moon times are computed, not fetched.
It's currently summer. Walleye typically hold 20-40 ft deep this time of year -- at an estimated 68°F, this looks like a strong time of year to target them.
20-40 ft
This is the seasonal depth band from the species model -- relative to this species' typical behavior, not this lake's actual structure. True depth relative to this lake's bottom contours needs lake bathymetry (tracked in issue #175).
Best times
Walleye feed most actively at Dawn and Dusk, when activity runs about 40% above the rest of the day.
Boosts feeding activity by about 40%.
Suppresses feeding activity by about 40%.

Boosts feeding activity by about 30%.
