Sun and moon are computed for Coral Bay; times are AWST. Tides are computed from the EOT20 global tide model at an ocean point 3.5 km from town (CC BY 4.0, DGFI-TUM) — model-derived and approximate, so treat times and heights as a guide. Astronomical tide above LAT, no weather surge. Not for navigation. Wind is an Open-Meteo forecast: hours shade darker as the wind builds (hatched = 20+ km/h sea breeze), arrows show where it blows toward, and hovering an hour gives the number.
