Urgent Notice

As a visitor to this web site, you might have noticed over the last few months that the digital weather station hosted at the SANSA Hermanus worksite, is not operating reliably anymore. After several attempts to revive the weather station, it was found to be too costly to repair.

So, until further notice, take note that the weather station has reached end-of-life and the data can not be considered to be accurate anymore.
