🎣 Solunar Table
Major Periods (2h)
Minor Periods (1h)
Based on the Solunar Theory (John Alden Knight): fish and wildlife tend to feed more during the periods when the moon is overhead or underfoot (major) and at moonrise/moonset (minor). The score considers the lunar phase and the crossing of major periods with the local high tide.

📘 About Guanica Tide Forecast
The coordinates for Guanica (17.96° N, 66.91° W) place this stretch of Puerto Rico's coast in the northern hemisphere. Its tidal pattern is diurnal (one high and one low tide per day), with a mean tidal range of 0.2m and spring tides reaching up to 0.3m. With less than half a metre of variation, water levels here are mostly driven by surface waves and atmospheric pressure changes. With a single daily high tide, the diurnal cycle makes it easy to pinpoint the best window for kayaking, surfing, and diving. Its geographic position creates unique interactions between oceanic swell and local tidal currents. Review the annual 2026 tide guide for Guanica, constructed with continuous high and low water forecasts measured in metres. In September, Guanica is in its autumn season, a key period for water sports, fishing, diving, and coastal navigation. MaréAgora calculations use harmonic decomposition calibrated via satellite altimetry and local gauges to ensure high accuracy.
