Two products, one coast

Why a forecast

01

Results lag

A water sample takes a day or more in the lab, so today's posting reflects yesterday's water or older.

02

Sampling is sparse

Many beaches are tested weekly or monthly, especially outside summer.

03

Official status first

We show the official call next to our forecast, never in place of it. When data is too stale to call, we say so.

Who it's for

The people who already reach beachgoers and boaters, and the agencies whose data makes this possible.
