Aarestation

Aarestation – Jump in the Aare? Get your answer in seconds.

Instead of checking a weather app, a hydrological data portal, and an air quality site separately, Aarestation shows you everything at a glance: is today a good day for an Aare swim in Bern?

THE PAI SCORE – YOUR DECISION-MAKER
The PAI algorithm condenses air temperature, wind, humidity, discharge, UV index, and water temperature into a single score from 1 to 10. A high score means the best possible conditions for jumping in.

MAI – YOUR VERY OWN SCORE
Every swimmer is different. With Mai (Mein Aare Index) you set your own target values and weightings for each factor – turning the general PAI into your personal Mai score, tailored exactly to you.
