In which month will blue tears appear?

Blue tears usually appear from April to August.

"Blue Tears" is a kind of planktonic fluorescent organism, which has a peculiar structure called luminous gland. When stimulated by waves, it will produce light blue light. It usually appears on the coast from April to August every year. When the weather is clear, the high tide in the south wind is the best condition to watch "Blue Tears". The correct taxonomic name of "Blue Tears" is Ostracoda, also called seed shrimp, which belongs to a crustacean. It is 0.2 mm to 2 mm long, has been petrified and lives in aquatic environment. "Blue tears" live on the energy of the sea, but when the waves wash ashore, blue tears leaving the sea can only live less than 100 second. With the disappearance of energy, Blue Tears' life is over.

Other factors: the phenomenon of "blue tears" will only appear when this kind of marine life, which is similar to the firefly's luminous mechanism, gathers in large quantities and is stimulated by the outside world (such as ships passing by and waves beating).
