Fishing enthusiasts can expect solid conditions, especially during the solunar major periods from 5 to 7 AM and 5 to 7 PM. With a fishing score of 7.7/10, the combination of tide changes and stable barometric pressure should yield some productive catches.

Keep an eye out for the low tide at 3:43 PM, which might limit access in some shallow areas. Looking ahead, expect a gradual increase in wave heights over the coming days, peaking at 2.5 meters by the 7th. Winds will also pick up slightly, with rain chances increasing later in the week. For today, though, diving remains your best bet—so dive deep and enjoy the tranquility and clarity of the waters around Sand Island.
