Tide Levels and Forecasts
- NOAA’s Tide Forecast for next 48 hours. This is better than the tide tables because it accounts for other factors, such as thermal expansion/contraction (due to El Nino/La Nina), winds, storm currents, and air pressure. It may not account for heavy rainfall.
- WET (Weather Events Tides). WET provides real-time and forecast tidal water levels for the US and weather worldwide for coastal locations. It combines NOAA astronomical tide predictions with proprietary forecast models to deliver more accurate water level estimates — especially during storm events when standard predictions fall short. You can set alerts for specific locations.
Emergency Information
- Marin County Public Emergency Portal – best source for local flooding locations and road closures. It also displays the alerts that were sent via AlertMarin.
- AlertMarin – sign up for emergency alerts or log in to your account to check to see if you are signed up for optional notification groups, such as “Coastal Flooding and King Tides”, “Significant Traffic Disruptions”, etc.
