Diary of Highlights

1st to 5th
High pressure persisted to the east with low pressure either over or to the west of Wales maintaining unsettled conditions. Winds were mostly from a southerly or south-westerly direction so temperatures overall were near or above normal. But it was often cloudy with showers and some longer spells of rain as well.

6th to 14th
High pressure was dominant to the east and then the north of the country maintaining much more settled weather with often dry conditions although there were some thundery showers around during the 9th and 10th. Winds from the east or north-east persisted through this period giving some warm days but others rather chillier, especially when cloudy. St Clears (Carmarthenshire) recorded a temperature of 25.6 °C on the 12th.

15th to 18th
Low pressure edged northwards from France giving mainly cloudy and sometimes quite wet conditions with occasional showers or longer spells of rain, some heavy with local thunder. Temperatures were mostly near normal.

19th to 31st
Although briefly drier and brighter over the 19th to 21st, much of this latter part of the month was again dominated by low pressure to the south giving persistent east or north-east winds and occasional showers or longer spells of rain, some of these heavy and thundery. A cool night on the 18th/19th, with Capel Curig (Conwy) recording a minimum temperature of 0.5 °C. The 26th was notable not only for the rain but also very strong north-east winds in the south. Velindre (Powys) recorded 34.0 mm on the 26th, with a highest gust of 74 m.p.h. at Mumbles (near Swansea).
