Weeknotes 2026.22

It was a quite successful week. I was able to successfully complete many of the tasks I had to do. Some tasks made me feel a little bit giddy.

This week a heatwave started, and we already had over 30 degrees. But the week finally brought a little bit of rain. I hope there will be more rain in the coming weeks.

According to the GeoSphere Austria we had in April in some places in Austria only 15% of the regular rainfall. Overall, we had 65% less rainfall in Austria.
