HUMBOLDT BAY • NORTHERN CALIFORNIA
Weekly tide charts.
Monday through Sunday.
Seven separate daily graphs show 4:00 AM through 2:00 AM the following day, each followed by its own hourly tide table. Blue shows NOAA tide predictions; red shows actual NOAA water-level measurements when available. Data refreshes every 15 minutes. At 2:00 AM Pacific each Sunday, the charts switch to the next week, and actual readings reset until NOAA measurements become available for the new week. The green current-time line updates every 2 minutes. These charts are intended to make tide information easier to scan at a glance.
