I got tired of checking three different sites just to find out the local beach had an algae warning – so I built something.

Rantapäivä (jaaskel.com/rannat.html) shows you:

• 🌡️ Water temperatures – live and forecast

• 🦠 Algae situation per beach

• ☀️ Sort by best weather, warmest water, or sunniest forecast

• 🌊 IoT sensor readings where available

It works on mobile and desktop. Still early days – coverage grows as more sensor data comes in.

Would love to know: which beaches matter most to you, and what data would actually make you use something like this?

i tried first with the capital area but decided to include the whole country. satellites above here are not too many and often, but something came out from those.
