Kaicast

KaiCast reads Hawaii's ocean the way a local diver does. Instead of a generic surf report, it forecasts the conditions that actually decide your dive — underwater visibility, surge, tide, swell, and wind — spot by spot, across all locations on Hawaiian islands.

Our Abyss forecast engine blends PacIOOS reef models, NOAA data, and marine forecasts, then sharpens each spot against real dive-log observations, so the read improves the more the community logs.

WHAT YOU GET • Per-spot ocean conditions across O'ahu, Maui, and the neighbor islands, up to 10 days out • A clear read on whether it's a go — with the drivers explained in plain language, not just numbers • A personal dive log to record what the ocean was doing on every dive • Hazard awareness: box jellyfish, brown-water advisories, and NWS marine warnings

Built in Ewa Beach by a freediver — for freedivers, spearos, snorkelers, and anyone who plans their day around the water.
