🏖️ Recommended Activities

🏊
Sea swimmingExcellent

At low tide the waters tend to be calmer.

🎣 Solunar Table

★★★★★
🌗Last Quarter

Major Periods (2h)

07:49 – 09:49Moon overhead
20:20 – 22:20Moon underfoot

Minor Periods (1h)

15:10 – 16:10Moonrise
02:30 – 03:30Moonset

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 Rio Dulce entrance Tide Forecast

With geographic coordinates of 15.83° N, 88.82° W, Rio Dulce entrance is a key coastal reference in Guatemala. Its tidal pattern is mixed semi-diurnal (unequal tidal heights across the day), with a mean tidal range of 0.5m and spring tides reaching up to 0.6m. Oyster and shellfish farmers exploit the 0.5–1.5m range to alternate aerial exposure and submersion in their culture beds. Mixed tides make planning more complex: the day's two high tides reach different heights, requiring careful study of the tide table before each outing. The speed and direction of tidal currents here vary seasonally with the region's prevailing winds. Review the annual 2026 tide guide for Rio Dulce entrance, constructed with continuous high and low water forecasts measured in metres. In September, Rio Dulce entrance is in its autumn season, a key period for water sports, fishing, diving, and coastal navigation. Astronomical tables for this site are processed using tidal harmonic algorithms and adjusted for regional bathymetry.

Astronomical prediction from a harmonic model — does not account for storm surge, meteorological tide, or extreme events.
