Six factors. One clear answer.

We pull from marine weather APIs, NOAA tide data, USGS river discharge, FWC red tide monitoring, and community reports to calculate a weighted score built around what divers actually care about.

🌬️

Wind Speed & Direction

Offshore winds mean calmer surface conditions. Onshore winds churn the water. We weight both speed and orientation relative to your site.

🌊

Swell & Wave Height

High swells make entries and exits dangerous. We track significant wave height and period from the nearest buoy.

👁️

Underwater Visibility

We factor in rainfall, wave surge turbidity, and red tide alerts to estimate underwater clarity — not just surface conditions.

🌡️

Water Temperature

Real-time sea surface temperature with wetsuit recommendations — know whether to grab your 3mm or 5mm before you leave the house.

↕️

Tidal Flow

Slack tide windows are gold. Incoming vs. outgoing affects visibility and drift. We map the full tidal cycle for your dive window.

〰️

Surface Chop

Short-period wind chop is brutal for surface swims and entries. A separate surface condition layer catches what swell height misses.

Raw data fetch

Real-time pulls from NOAA, marine weather APIs, and buoy telemetry — updated every 2 hours.

Per-factor scoring

Each variable is normalized to a 0–100 scale based on diver-validated thresholds for safe, marginal, and poor conditions.

Weighted aggregation

Visibility and wave height carry higher weight. Surface chop and tide are modifiers. The composite score is your go/no-go signal.

Plain-English verdict

Every score comes with a short condition summary so you always understand the why, not just the number.

Everything you need, nothing you don't.
