Sailing in Hong is gorgeous in the early spring because whilst sunny and warm there is no trace yet of the dreaded humidity.
There is a disturbing natural disruptor though: Red Tide.
The pink reddish algae bloom is a natural phenomenal and is harmful to marine life. The resulting contaminated seafood may cause serious harmful neurological symptoms in humans. Watch your oysters and clams!
Red Tide occurs from early spring to late summer and varies greatly in intensity.
Apart from decaying marine life, the main culprits are air pollution and urban run off.
Red tide could be avoided by careful ecological management in coastal areas but I bet less than 10% of school kids have ever heard or experienced Red Tide.
Educators in HK please make our youngsters aware!
