Concept · tide & swell forecasts

Read the water before you paddle out.

Neap weighs swell, wind and tide for the break you're standing at, then gives you one call for the next few hours.

The tide, by the hour.

Drag across the day. The marker, the tide staff and the call follow you on one spring, then settle.

What Neap watches for you

Less chart reading, more water time.

One call, not twelve charts

Swell size and period, wind and tide are weighed for your break and boiled down to one word: flat, marginal, fun or firing.

Alerts that know your board

Tell Neap you ride a longboard and it stops waking you for overhead closeouts on the reef.

Tide tables that work offline

The week's tides and the last forecast stay on your phone for the car park with one bar of signal.

Your spots, best first.

Save a break and its call comes first. None of these places exist, but the hearts work.
