Thank you Jordan, Mark, Alexandra and Maurits.

Alexandra: 13 out of 14 days from 12th till 25th and 18 out of 23 days from 3rd till 25th, which is quite unusual for my location. Had a few days with heavy rain now (which was really good for crops, gardens etc), but it looks like there will be at least partially clears skies in the days to come.

Best regards,
Arne
