There is an update on red drift algae on Sanibel on www.mysanibel.com. It's back along some areas of the beach.
"CURRENT SANIBEL BEACH CONDITIONS
AS OF 3:00 P.M. – JUNE 22, 2006
As of 3:00 p.m., June 22, 2006, the Lighthouse Beach and Bowman’s Beach have minimal amounts of red algae. The beaches from the Sundial area to Tarpon Bay Beach have a small amount of red algae that should not pose a problem for beachgoers. Beginning just west of Tarpon Bay to the west end of West Gulf Drive, there is a fairly heavy amount of red algae that is affecting shellers and beachgoers. Only a thin coat is on shore but a 10-15’ wide swath of the Ceramium and associated brownish water (due to the bacteria involved in its decomposition) is in the surf zone, just like a few weeks ago. Blind Pass has a moderate amount of red algae present as well. At this point, directing beachgoers to Lighthouse Beach, Gulfside City Park (Algier’s) or Bowman’s Beach is recommended."
