Species context

Why this score

Good (61/100) for Largemouth Bass: water is estimated at 60.9°F, below Largemouth Bass's 70-85°F optimal range. Best window: Dusk — boosts feeding activity by about 30%, one of their peak feeding windows. That hour also overlaps a minor solunar period. 29.96 inHg and stable pressure modeled flat — no change from this fish's baseline. Light (5-10 mph) wind modeled about 15% above this fish's baseline.

What's driving the 7 PM score

Light window (dusk) is doing the most for this score. The score gives up the most on water temperature — 60.9°F estimated, about 24.3 points below its best.

Show the numbers behind this
  1. Water temperature: 60.9°F estimated

    15.7 of 40 pts

    Optimal range 70-85°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.

  2. Light window: Dusk

    25 of 25 pts

    Boosts feeding activity by about 30%

    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.

  3. 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.

  4. 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.

  5. Wind: Light (5-10 mph)

    10 of 10 pts

    Modeled about 15% above 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: Fall — ×1.00 (100% of the ungated score)

How catchable Largemouth Bass 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 69.3 of 100 points, and the two multipliers above take that to 69. 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

  • Water clarity. We have no source for it and do not estimate it.
  • Measured water temperature. The figure in the breakdown is a model over forecast air temperature, not a reading from a buoy or a probe.
  • Baitfish and forage activity.
  • How much fishing pressure this water has had.
  • Where the fish actually are. Depth bands are the species' published seasonal ranges, not an observation of this lake.
  • What anyone actually caught. No catch reports feed this score.

Conditions read from the National Weather Service as of Sep 12, 2026 at 6:40 PM CDT. Solunar periods and sun/moon times are computed, not fetched.

When best caught

It's currently fall. Largemouth Bass typically hold 5-15 ft deep this time of year — at an estimated 60.9°F, this looks like a slower time of year to target them, since water temp is outside their optimal range.

Current depth

5-15 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).
