Hawaii dive & ocean forecasts

Free · Designed for iPad. Not verified for macOS.

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.

- Conditions now show where each reading came from and how recent it is, and no longer show a live badge or an all-clear the forecast hasn't confirmed. - The Swell card names the wave model behind its numbers instead of saying there isn't one. - Explore: the recenter button works even when GPS is slow, and the map layer controls no longer disappear behind the spot sheet. - A redesigned Pro page, laid out properly on iPad instead of a stretched phone layout. - Profiles: dive reports carry the diver's name, profile photos load reliably, and a new privacy toggle in Settings. - A cleaner launch screen, loading placeholders instead of spinners, and repeat condition alerts no longer re-send every hour.
