How Long Does Red Tide Last?
Red tide blooms can last from days to months depending on currents, nutrients, wind, and bloom intensity.

If the sample age becomes older than the usual 8-day live sample window, this card will mark the page as outside window and say that no newer matched FWC sample was found. Freshness is based on public FWC sample dates and the static page build time.
There is no single duration that applies to every beach. A nearby sample can change as water moves, so status pages should be checked with the sample date and location visible.
RedTideToday uses the latest public FWC sample window for current pages and keeps historical records separate from today's status.
