The basics are already functional, at this point it is mostly about finetuning the algorithm and adjusting the variables to make the simulation realistic. The first column shows date in DD.MM., then temperature in celcius, rain stats, and snow thicknes in cm. The last column is for water: positive values are water temperature in celcius, negative values are ice thickness in cm.

Here we see how the water already freezes at the end of October, then the heavy rainfall destroys the ice, until it gradually freezes again at 17th of November.
