What actually drives the muskie year — temperature or daylight?

Both, in different roles: photoperiod is the calendar and temperature is the trigger. Shortening or lengthening daylight sets hormonal state — gonad development through fall and winter, spawning readiness in spring — which is why the sequence of the muskie year never reorders. Temperature then decides the exact dates: spawning fires when spring water hits 9–15 °C (48–59 °F), the fall feed ignites as lakes drop through the low teens Celsius (mid-50s °F). A freak warm week in March cannot make muskie spawn, because daylight has not armed the system yet; a cold late spring simply slides the whole schedule back.
