Weather influences

Heat

The heat of August and September are influences that allow dinoflagellates to bloom and out-compete non-toxic plants that bloom earlier in the year.

Wind

The following charts and graphs show that the prevailing winds of July and August were from the South. The graph shows a full week of west winds during the first week of August and from the 14th to the 22nd of July.

They support our contention that a concentration of nutrients that has brought algae blooms and fish kills was a continuation of a chain of events. The chain began with the introduction of excess nutrients (over the course of years). The chain grew with blooms of macro-algae and Gracilaria in early summer. It continues with the accumulation of those algae bloom rafts on the east side of the Indian River Lagoon and it leads to the fueling of a centralized dynoflagellate bloom that has become toxic to fish. Dead fish only add to the nutrient load in the Indian River Lagoon. The nutrients present in the plant matter again become available to fuel blooms of Macro-algae and blue green algae and the process becomes circular. The cycle will not be broken until limits are placed on the introduction of excess nutrients into the waterbody.
