Wednesday’s Respiratory Irritation Forecast
Wednesday, March 29 — Some beaches may experience a MODERATE risk of respiratory irritation from Karenia brevis (red tide) in CHARLOTTE, COLLIER, MANATEE and PINELLAS counties, according to the forecast by NOAA’s National Centers for Coastal Ocean Sciences.
Karenia brevis (red tide) is also present along the coast at concentrations that may cause respiratory irritation with onshore winds in LEE and SARASOTA counties.
Conditions may vary, depending on wind direction and currents. Risk of respiratory irritation is most likely when winds are blowing onshore or alongshore, and less likely when winds are blowing offshore.
Today’s forecast indicates alongshore winds from a northeasterly direction, shifting to an onshore westerly direction in the afternoon.
Water samples collected by the Florida Fish and Wildlife Commission indicate red tide blooms at moderate to high concentrations off Pinellas and Manatee counties.
The NCCOS forecast map below projects levels of respiratory irritation anticipated over the next 24 hours along Southwest Florida shoreline. The respiratory forecast takes into account expected wind strength and direction.

Changing wind speed and direction may change this forecast for respiratory irritation. A MODERATE to HIGH risk of respiratory irritation is most likely when winds are blowing onshore or alongshore, and less likely when winds are blowing offshore.

FWC Red Tide Samples Report, 3/24
Friday, March 24 @ 5 pm –Over the past week, the red tide organism Karenia brevis was detected in 79 samples along Florida’s Coast.
Moderate to high bloom concentrations (greater than 100,000 cells/liter) were present in only five samples: three in Pinellas County and two in Manatee County.
Red tide is potentially harmful to people at 10,000 cells/liter.
- In Southwest Florida over the past week, K. brevis was observed at background to medium concentrations in and offshore of Pinellas County, very low to medium concentrations in Manatee County, background to low concentrations in Sarasota County, background concentrations in Charlotte County, background to low concentrations in Lee County, and background to low concentrations in and offshore of Collier County. For additional information, view the Southwest Coast report and map.
- In Northwest Florida over the past week, K. brevis was observed at background concentrations in Bay, Gulf, and Pasco counties. For additional information, view the Northwest Coast report and map.
- Along the Florida East Coast over the past week, K. brevis was observed at background concentrations in one sample from Palm Beach County. For additional information, view the East Coast report and map.
Reports of fish kills suspected to be related to red tide were received from Southwest Florida over the past week from Pinellas, Sarasota, Lee, and Collier counties. For more details, please visit https://myfwc.com/research/saltwater/health/fish-kills-hotline/ and https://visitbeaches.org/.
Over the past week, respiratory irritation suspected to be related to red tide was reported via the Beach Conditions Reporting System and/or the Fish Kill Hotline in Southwest Florida in Pinellas, Manatee, and Collier counties.

Red Tide is MUCH worse than it's made out to be - it's played down because Billions of dollars are at stake. Fixing it? No way - Mosaic funds Mote. The Gov. has made it clear (Scott and DeSantis) that environmentalism is a "woke" fantasy,.
People are getting very sick. Talk to Doctors. Some are moving away (to the east coast).
This is not just an irritant - it's a poison (duh, dead fish and manatees/dolphins). It is likely shortening human lives - those with other respiratory problems.
It's been studied - but, of course, not by the State. Why would they want to know the truth? You can't dump billions of gallons of sewage and fertilizer into shallow warm water without problems!

The red tide can bother you at sometimes. But whiat our family does is just go down the beach a couple miles and you really can’t notice it at all. Sometimes it’ll bother you worse than others. But don’t give up hope our Florida weather is beautiful and so are the beaches so just enjoy it the best you can and except the red tide Kim Wroblewski

Thank you for publishing information about red tide. This has been going on for several weeks not just this last week. I live near the beach in Sarasota county. I feel so bad for tourists who come down with no idea that this is going on. It is not publicized or reported much. The signs alerting people are very inconspicuous. Many lodging properties and hotels do not tell their guests. We’ve also had closures due to bacteria in the water. It is bad enough that our state government is not proactive in solving this problem for all of us, but at least tell people what’s going on for safety reasons. Florida rambler is awesome. Thank you for all your publications! Susan
