The Marin King Tide Outlook shows which low-lying streets in Corte Madera, Larkspur, Greenbrae and east San Rafael are likely to flood on the next high tides. It covers 246 streets, each checked against its own flood lines, which come from lidar and, where available, resident photos.
What does it do?
- Pick a street to see its flood lines and the next tides that reach them.
- A 14- and 30-day outlook of each day’s highest tide, colored by flood level at each location.
- A daily forecast that adds the current sea-level anomaly and forecast pressure and wind to NOAA’s prediction.
- A Kelvin wave watch that tracks the El Niño sea-level bump moving up the coast.
Why this year?
This fall’s El Niño is raising sea level along the coast above what the standard tide tables predict, so a tide that would normally stay in the channel can reach the street. The outlook adds that measured anomaly to NOAA’s predictions instead of relying on the tide table alone.
What are the limits?
Storm surge isn’t included, so a storm on a flood-tide day adds more water. Beyond about two weeks, treat the outlook as a rough guide, because the anomaly can grow or fade.
