Typical water visibility

Summer visibility around Islamorada is commonly reported in the 30 to 70 ft range, a community guidance estimate, not a measurement. Rain, river discharge, swell mixing, and seasonality can shift real conditions dramatically day to day.

The app shows a model estimate of today's visibility here, with a confidence figure.

Islamorada spearfishing map: reefs and wrecks

The reefs and wrecks layer in the app marks charted wrecks, reefs and obstructions around Islamorada, where sources have them. Tap one for the seabed depth beside it (an estimate where no chart reports one), the least depth over the structure where a chart sounding exists, and today's conditions at that spot. The structures are merged from NOAA nautical charts and other public sources, so coverage is densest in US waters. It's a Pro map layer.

Safety in the water

Every safety tool in Submarius is free. With Safety Watch you set a "back by" time and pick who watches. If you don't check in by then, the server alerts them by push or email, even if your phone is dead. It needs a free account and never contacts the coast guard.

In Spearfishing mode, a shark awareness card lists shark species recorded around Islamorada (from OBIS records, for awareness, not live tracking) and community sightings from the last 48 hours, when the area has any. Signed in users can report a sighting, and app users within 25 km get a push.
