While it's been less than a year since 2020's 6 week long bioluminescence streak along Southern California, this years so far is starting off similar with faint blue in some waves and some brighter waves here and there. IT may be getting better although some nights haven't shown might blue glow. So far Crescent Bay in Laguna Beach ad Crystal Cove seem to be the best b ut it varies every night depending on the conditions which are not really predictable except for the fact that there needs to be red tide for it to happen (not to mention sunlight during day, proper currents, etc...). The most common question that gets asked, "Where will it be tonight?" There is no answer for that since we don't know.
Bioluminescence is back for 2021!
Here are some tips to look for the blue waves:
1. Check out several different beaches as the red tide can fluctuate each day/night
2. There is no better time of night, some nights there is more glow early while other nights there is more glow past midnight. As long as the sky is completely dark with no light from the sun, it will be visible
3.Check social media to see where people are posting using the #bio2021 or #bioluminescence
