Regional Tide Intel

Tide & Current Flow by Region

How tide direction is impacting boating conditions

Fernandina Beach

  • ·Ebbing tide through 10:46 AM creates strong southbound current
  • ·Nassau Sound passes run hard on outgoing tide
  • ·Incoming tide begins late morning, slack around 10:30 AM

Mayport / St. Johns

  • ·Strong ebb through 10:29 AM stacks chop at entrance
  • ·River outflow against southeast wind creates standing waves
  • ·Slack tide around 10:30 AM best for crossing bar

Ponte Vedra / Guana

  • ·Minimal tidal influence, ocean swells dominant factor today
  • ·Good clarity with light runoff
  • ·Southeast winds keep nearshore zone moderate chop all day

St. Augustine

  • ·Inlet ebbs hard through 10:08 AM, steep chop
  • ·Matanzas River outflow adds to ebb current strength
  • ·Slack around 10:00 AM, incoming tide begins late morning

Best Region Today
Offshore waters show slightly lighter winds this morning, best choice for calmer ride early
Best Use Case
Nearshore structure fishing or reef runs work well in these mixed seas if you depart early
Return Ride
Afternoon return faces building 15-knot southeast winds and moderate chop, plan for jarring head sea
Bill's Strategy Note

"Southeast winds 10-15 knots with confused lumpy seas from mixed southeast chop and east swell, jarring on every heading. Best approach is early morning departure before winds build. Launch by 7:00 AM, return by noon before afternoon increase to 15 knots."
