Canadian Solunar Forecaster
John Alden Knight's Solunar Theory tailored to Canadian geography. Predict the precise 2-hour major and 1-hour minor wildlife feeding periods across Great Lakes, Canadian Shield waters, and Pacific estuaries.

Moon directly overhead. Maximum gravitational alignment triggers intense feeding activity in predatory fish.
Moon directly underfoot on opposite side of Earth. Secondary prolonged 2-hour feeding window.
Coincides with lunar crest above horizon. Heightened strike rate along shallow dropoffs.
Lunar transit setting past western horizon. Excellent topwater bite opportunity.
Prime morning hard-water and spring open-water troll for lakers and jumbo perch along 30ft weed edges.
Lunar & Solar Ephemeris
The Gravitational Trigger
When the moon is directly overhead (lunar transit) or underfoot (opposite meridian), gravitational pull reaches its apex, triggering heightened metabolic activity and predatory instincts in fish and game.
Major vs. Minor Periods
Major periods span approximately 2 hours surrounding lunar zenith and nadir. Minor periods last 45–60 minutes coinciding with moonrise and moonset. Bites peak if these align with sunrise or sunset.
Barometric Synergy
Solunar feeding windows produce the strongest results when paired with a falling barometer 2–4 hours ahead of a passing low-pressure frontal boundary.
