At low tide the waters tend to be calmer.
Access only within the 2 hours near the lowest tide.
Ask the skipper about the conditions.
🎣 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 La Union Tide Forecast
La Union is located at 13.33° N, 87.82° W on the coast of El Salvador, in the northern hemisphere. Its tidal pattern is semi-diurnal (two high and two low tides per day), with a mean tidal range of 2m and spring tides reaching up to 2.5m. Shellfish gatherers and line fishers exploit these mid-range tides to access reefs and rocky outcrops exposed at low water. The semi-diurnal cycle flushes coves frequently, shortening water residence time and maintaining high oxygenation levels. The coast here is influenced by large-scale ocean currents that modulate water temperature throughout the year. The 2026 tidal schedule for La Union provides a full-year calendar of high and low waters alongside predicted sea levels. In September, La Union is in its autumn season, a key period for water sports, fishing, diving, and coastal navigation. Predictive modeling employs updated local oceanic constants, ensuring minimal margin of error in peak tidal timing.
