Sun, moon & best fishing times

Sun & moon at Great Moose Lake

Best fishing times

Major periodMinor periodDaylight

    Based on solunar theory, an estimate. Major periods (about 2 hours) center on when the moon is directly overhead or underfoot; minor periods (about 1 hour) center on moonrise and moonset. The 0–100 activity score rises during those periods and gets a boost near sunrise and sunset and around the new and full moon. Weather, water temperature and pressure often matter more. Sun and moon times are calculated in your browser from the lake's coordinates with standard astronomy formulas, shown in ET (America/New_York), and accurate to within a few minutes.
