Red Sea Water

If there’s fish on the beach then there is a clear sign that something is amiss in the water. Ignore the warnings and the consequences could be dire. Such an occurrence indicates a red tide, an algal bloom in the sea, when toxic algae has built up to such a level that it is harmful to health.
The fish in particular find themselves in the firing line — hence their presence on the sands. But for humans too, conditions in the water can cause problems.
Respiratory issues are commonplace for those who ignore nature’s warning sign, with coughing and severe throat irritation amongst the symptoms. It isn’t deadly, but it is uncomfortable and our best advice is to avoid exposure at all costs.
Other tell-tale signs include water that has turned red or sometimes brown. However, this isn’t always the case and, for those keen to get a heads-up, fish on the beach remains the best indicator of all.
