Marine Metrics

Marine Metrics is a clean, dark tide app for surfers, anglers, boaters, kayakers and anyone who plans around the water.

Open it and you see where the tide is now, whether it is rising or falling, and when the next high and low arrive. Drag across the curve to read the height at any hour.

TIDES FOR ANY COAST
• Tide heights, high and low times, for almost any coastal point in the world
• United States waters are predicted from NOAA's official tide stations
• Everywhere else is covered by a worldwide harmonic tide model
• Inland? The app finds the nearest coast for you and says how far away it is

A CHART YOU CAN READ
• A smooth tide curve with a NOW marker
• Drag along the chart to read the height and trend at any hour
• A 24-hour profile for each day, with every high and low marked

THE REST OF THE DAY

• Sea-surface temperature from NOAA satellite observations
• An hourly table of tide height, trend, wind speed and wind direction

YOUR SPOTS
