Those who have been visiting the south of Europe for the last weeks know what the title of this post means. The weather in the Douro valley, in Portugal, and also in many areas of the Mediterranean has been wonderful. Clear sky with sunshine from sunrise until sunset and warm temperatures during day time. If we wouldn’t live out of agriculture, more precisely vine growing, this would just be a perfect weather. But sunshine means no rain and vines need water for the new season which is about to start.
