When Do Northern Pike Bite?

Last updated: 2026-09-26

Public app: This model has been available since version 1.6.6. The changelog also records older models, which no longer describe the current rating.

Short answer

PrimeBite gives Northern Pike one daily rating from complete daily wind and moon phase. Dusk is shown separately as the best evidence-backed time to fish, but it adds no points to the all-day number.

This page documents the current Northern Pike variables, their sources, and the model's limits. We keep exact numeric tuning private.

How it works (overview)

Northern Pike uses a freshwater all-day rating with no Major/Minor bite times. Complete local-day mean wind has the larger scored range, and moon phase has the smaller range. Exact numeric tuning stays private.

The app's direct breakdown has only three rows: Starting point, Daily wind (X mph average), and Moon phase. They add exactly to the shown rating. Dusk appears separately as best-time guidance and adds no score points. If even one expected hourly wind value is missing, PrimeBite shows no Pike rating for that day; the local dusk time can still appear.

Pike is rated once per day, not by the hour. Arlinghaus 2017 studied two one-week experiments at the same lake as Kuparinen. Its model did not detect a diel-period or within-day weather effect, but conditions changed little within those days. This limited result does not prove Pike never vary by hour. An hourly rating would go beyond the direct catch evidence used here.

Study limitations (Kuparinen 2010)

Northern Pike is anchored to a single peer-reviewed open-access study — both scored drivers and the dusk timing result cite this same paper. We disclose these limits so users do not assume ratings apply everywhere:

PrimeBite uses these findings to inform a 1-to-5 rating; the exact numeric conversion remains private. Ratings are relative indicators, not guarantees.

Variables and model choices

Research-backed means the driver/pattern is supported by open-access sources. Model choices are PrimeBite's disclosed, evidence-bounded decisions; the paper did not publish PrimeBite rating points.

Moon phase

Research-backed: Pike catch rates peak around full and new moon.

Implementation: the rating favors new and full moon over quarter phases; the exact response stays private. Moon phase is checked at local noon for the fishing date.

Wind speed

Research-backed: within the observed range in Kuparinen (2010), higher wind speed is associated with increased catch rates.

Implementation: wind is the larger scored driver; the model does not extend the observed benefit indefinitely. The input is the complete local-calendar-day mean. Partial days get no rating.

Today, Forecast, and Alerts require every expected wind hour, including shorter or longer daylight-saving days. New Logbook predictions use a separate context: complete rolling 24-hour wind history ending at the catch time. Incomplete history produces no saved prediction. Old saved predictions stay unchanged.

Dusk / civil twilight

Research-backed: Pike catch rates are higher during dusk.

Implementation: local civil twilight is displayed as the best time. It adds zero points because each rated all-day unit already contains dusk, and the study does not provide an all-day effort share that varies by day.
