An algal bloom has turned the water red down at Shelly this morning, which could signal bioluminescence for this evening.
The the algae caused a vibrant blue bioluminescence already before sunrise this morning, similar that pictured by Jarvis Liu in Palm Beach earlier in the week, so it could return when night falls.
This is not entirely uncommon and is not a pollution event.
It is likely Noctilluca Scintilla or sea sparkle or sea twinkle, a red algae.
Algal blooms occur in response to changes in temperature or rain or nutrients in the water. They are little organisms, so while not toxic to humans it can cause a bit of skin irritation.
