Sea Sparkle Predictor

Predict the best nights to witness the magical glow of bioluminescent sea sparkle (Noctiluca scintillans) along coastlines worldwide. The app calculates a real-time likelihood score from 0 to 100% based on six environmental factors including sea surface temperature, wind speed, wave height, cloud cover, seasonality, and warm weather streaks. With 83 preset locations across 26 countries including the Netherlands, Belgium, United Kingdom, Germany, France, Denmark, Australia, New Zealand, Italy, Spain, Portugal, Taiwan, China, Japan, South Korea, India, Maldives, Thailand, Vietnam, USA, Puerto Rico, Jamaica, Mexico, and South Africa, plus custom coordinates for any coastal location, you can trigger smart home actions when conditions look promising. This app is a prediction tool based on environmental conditions, not a guarantee of bioluminescence. Actual sea sparkle occurrence depends on many additional factors including the presence of organisms and local water chemistry. Weather and marine data is provided by Open-Meteo.
