31 daily loops trace Santa Barbara’s predicted tides for October 2026. Angle gives the GMT hour: midnight above, clockwise, one turn per day.
744 hourly NOAA predictions, station 9411340, in meters above MLLW. Public domain.
Radius measures height above this month’s minimum (−0.213 m MLLW), so the center is not zero MLLW. The red dot marks the 2.020 m maximum. One linear radial scale; line width is fixed. Weather can move actual water levels away from these harmonic predictions.
Arrows step hours; Shift steps days. Home/End goes to the month’s start/end. Reduced motion skips the reveal.
