From April to September each year is the peak season for the blue tears phenomenon in Matsu. This week, many tourists and locals began noticing faint blue glows on the sea surface. Unexpectedly, on the evening of the 15th, the blue tears erupted in an unprecedented volume, prompting many residents and netizens to take photos and check in. Social media was flooded with blue tears photography, and some locals even exclaimed they had never seen such an intense blue before.

Matsu’s blue tears have been ranked among the world’s top 15 wonders. Catching a massive display is a rare and unpredictable event. The brightness of the blue tears is influenced by tides, ocean currents, moonlight, and light pollution, and the experience can vary greatly depending on the location. This recent outburst was a once-in-a-year cosmic-scale event across Matsu’s four townships and five islands, happening no more than five times annually. The timing is also difficult to predict. The evening of the 15th marked this year’s first major occurrence, drawing many tourists and photography enthusiasts eager to witness the phenomenon.
