    There was virtually no sun, just 5 minutes, and the lowest UV level in May.

    Another cool night followed with the thermometer falling to 4.5C being 2.5C below average.

    Sunday arrived with broken sun initially, but by the time readings were taken at 08.00 the sunshine was much stronger and continuous with the thermometer having recovered to 9.1C.

  • Temperature & UV down again

    The UV level on Friday was the lowest this month as sunshine was limited (1.6 hours)and intermittent.

    Saturday has arrived with intermittent sunshine and the thermometer having recovered to 8.2C at 08.00 but there is noticeably less wind than on Friday.

  • Very cool night after much sunshine

    Thursday brought us 12.67 hours of strong sunshine although the UV level had dropped back to ‘High’. The maximum of 17.3C was down for the fourth consecutive day, but average for May, due to the very brisk northwesterly wind.

    The clear skies overnight meant that the thermometer fell away until 5am when a low of 2.4C as reached.

    Friday has dawned with broken cloud and intermittent sunshine that has lifted the temperature to 9.2C at 08.00.

  • UV rises into the ‘Very High’ level on Wednesday

    Wednesday saw a lot of bright weather but sunshine amounts were much reduced from previous days with just 3.37 hours logged. As a consequence of the reduced sunshine and brisk westerly winds the maximum of 18.3C was lower than the previous five days but still 1.5C above average.

    The notable aspect of Wednesday was the much increased UV reaching into the ‘Very High’ level with a reading of 8.4.

    The first light rain from the next weather front started to fall just after 8 pm with another shower around midnight but no great quantity was recorded, only 0.5mm.

    At dawn on Thursday the evidence of the hang back of cloud from the overnight weather front was seen moving eastwards allowing the sun to break through at 06.10. The overnight minimum was set at 06.11 with a reading of 6.8C that began to recover rapidly as the sun cleared the cloud so that by 08.00 the thermometer read 9.4C.

  • Atlantic air flow means cooler weather and less sun

    Tuesday brought us 11.4 hours of sunshine but the cooler, moister air from the Atlantic, brought on a brisk westerly air flow, meant that the temperature was well down on previous days, although the peak warmth of 20.3C was 3.5C above the May average. However, that maximum was a full 8C down on the previous day.

    It was the sixth consecutive dry day. Evaporation from ground and plant life over the first eight days this month now totals 28mm whereas the rainfall is just 8.1mm. That is quite a change from the wetter than average months of March and April.

    Wednesday dawned with thick fog reducing visibility to 150mm at dawn but slowly thinning to 1,500m by 08.00, as a result of the still air and cooler minimum of 5.8C overnight.
