🎣 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 San Juan Tide Forecast
Situated along the coastline of Peru (-15.37° S, 75.20° W), San Juan lies in the southern hemisphere. Its tidal pattern is mixed semi-diurnal (unequal tidal heights across the day), with a mean tidal range of 0.6m and spring tides reaching up to 0.8m. With tides reaching up to 1.5m, local fishers typically work around the two hours flanking high tide to benefit from stronger flow. Sport fishers in mixed tide regions target the day's higher high tide when chasing predatory coastal fish. Tidal dynamics in this bay or inlet are shaped by the geometry of its entrance, which can amplify or reduce range relative to the open sea. Review the annual 2026 tide guide for San Juan, constructed with continuous high and low water forecasts measured in metres. In October, San Juan is in its spring 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.
