🏖️ Recommended Activities

🏊
Sea swimmingExcellent

At low tide the waters tend to be calmer.

📸
Natural PoolsExcellent

Access only within the 2 hours near the lowest tide.

Nautical ToursGood

Ask the skipper about the conditions.

Minor Periods (1h)

07:0408:04Moonrise
21:1422:14Moonset

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 Heeia Tide Forecast

In the northern hemisphere, the coastal area of Heeia (United States) is positioned at coordinates 21.44° N and 157.81° W. 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 0.9m. With tides reaching up to 1.5m, local fishers typically work around the two hours flanking high tide to benefit from stronger flow. Mixed tides blend characteristics of diurnal and semi-diurnal patterns — the morning tide may differ greatly from the afternoon tide in height and current. Coastal water salinity varies with rainy seasons, creating gradients that influence the distribution of marine species. Access the updated 2026 tide table for Heeia featuring exact high and low water times, ranges, and coefficients for boating and angling. In September, Heeia is in its autumn season, a key period for water sports, fishing, diving, and coastal navigation. Reported times and heights derive from fundamental harmonic component analysis (M2, S2, K1, O1) applied to these coordinates.
