• Seasonal Patterns

  The range across the year is 46°F to 72°F. The hard part of the year is the heat, not the cold. The cooler months are the comfortable ones to be out. Autumn steadies things again once the heat lets go. Expect Piper Slough to follow that timing. Spring fish sit shallower than most people expect.
