Although the start of June brought intense thunderstorms, especially on 1 and 8 June, dry and settled weather from the end of May dominated the first two weeks.
There was a break in the fine weather for the third week of the month, however, Storm Hector passed close to the northwest, giving two days of rain and gales.
This was the last significant rainfall for farmers as thereafter there has been a surge in temperatures. From 21 June, a settled and exceptionally dry period followed, with a heatwave and partial drought conditions reported. Farmers have had to turn to forms of irrigation to fight the weather, with dairy farmers in the douth being particularly badly affected.
