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 Puerto Herradura Tide Forecast
With geographic coordinates of 9.65° N, 84.67° W, Puerto Herradura is a key coastal reference in Costa Rica. Its tidal pattern is semi-diurnal (two high and two low tides per day), with a mean tidal range of 1.9m and spring tides reaching up to 2.4m. Shellfish gatherers and line fishers exploit these mid-range tides to access reefs and rocky outcrops exposed at low water. The regularity of semi-diurnal tides — two highs and two lows approximately 6 hours apart — simplifies crossing planning and fishing scheduling. This shoreline is subject to seasonal wind and pressure variations that can affect tide height by up to 0.3m during extreme events. Review the annual 2026 tide guide for Puerto Herradura, constructed with continuous high and low water forecasts measured in metres. In September, Puerto Herradura is in its autumn season, a key period for water sports, fishing, diving, and coastal navigation. Our oceanographic database syncs historical gauge records to refine harmonic coefficients for this stretch of coastline.
