7-day fishing planner

Each day’s tides, light and solunar windows. Stars are a simple outlook from moon phase and how well the windows line up with dawn and dusk — a planning aid, not a promise of fish. How we calculate this.

Slack water

There is no NOAA current prediction station within 25 km of this gauge. Around the open coast the water is usually slackest near each high and low tide (the “stand”); in inlets and rivers the current can keep running well after the tide turns.

King tides in the next 12 months

Highest predicted high tides at this station (MHHW here is 2.2 ft). Storms and onshore wind can add to these.
