Charts

Combined analysis chart — heights, ΔT, ΔH on left axis; surge, pressure, wind, wonrange on right. Choose x-axis: hours-from-HW, hour-of-day, or Walton range. Best Fit per dataset, Line/Dots toggle, point counts in legend

Multi-variable tide chart — heights, deltas, wind, pressure · dual Y axis · HW offset mode

High Water timing and height differences relative to Walton HW — ΔT (minutes) and ΔH (metres) by location, with WL surge

Low Water timing and height differences relative to Walton LW — ΔT (minutes) and ΔH (metres) by location

Near real time tide level from Waldringfield Boatyard gauge with 5 minute refresh, period can be selected up to 48 hours

Near real time tide level from Suffolk Yacht Harbour gauge with 5 minute refresh, period can be selected up to 48 hours

WL surge (red) against Fort Massac pressure (blue) with optional wind speed (green) and wind direction (orange) — scales cropped for comparability

Tidal rate of change (m/hr) plotted against hours from Walton High Water — scatter view of rising/falling rates across tidal cycles, filterable by range, surge and phase

For each Walton HW, the timing offset (ΔT, minutes) at WBY, WB, BWD, WL and FTMassac plotted against the hour-of-day at Walton — reveals diurnal patterns. Right axis selects mastertides scalars at HW (surge, pressure, wind)
