Reading the Calendar
- • Cell color shows the daily tide type: spring (blue), mixed (teal), neap (gray).
- • ↑N / ↓M shows the count of high and low tides that day.
- • Moon emoji indicates the lunar phase, which modulates tide range.
- • Spring tides (full/new moon) yield larger ranges; neap tides (quarter moons) yield smaller ranges.
Tide predictions are computed from global harmonic constituents (FES2022b) with UTide harmonic-analysis fallback based on UHSLC observations, times shown in local timezone.
