  • Second wettest day this month BUT only 3.3mm

    A virtually sunless day yesterday but still above average maximum of 20.7C (+1C). In the early evening the first spots of rain fell with heavier showers late evening. The total rainfall was 3.3mm, making it the second wettest day this month but still only brings the total for June to 62% of the 33-year average.

    Gardeners and farmers will be disappointed at this little rainfall as it only dampens the top 1cm of soil.

    This morning has dawned with very low cloud giving misty conditions and visibility down to 800 metres. Humidity at 08.00 was 98%, the highest this month. It was a mild night with the thermometer only dropping to 13.9C (+4C) and light winds.

  • Exceptionally dry air with humidity 69% at 08.00, driest for two years

    The temperatures recovered yesterday due to a drying easterly wind that has not been seen for a month. There were 4.22 hours of strong sunshine that boosted the temperature to a maximum of 23.0C, which was 3C above the average, at 15.01. More cloud in the afternoon restricted the thermometer from rising further.

    At times the anemometer fell still during the daytime and evening yesterday with a maximum gust of 11mph.

    Another dry day with the total rainfall standing at 31.1mm and the evaporation from ground sources ad plant life now three times the rainfall at 91mm. Rain is forecast later today and tomorrow so the gardens might have some relief.

    It was a very mild night with a minimum of 13.3C that had recovered to 16.3C at 08.00 with still movement of air from an eagerly direction.

    The humidity at 08.00 was 69%, the lowest at this time of day since 1st July 2015 when 62% was recorded.

    Yesterday:

    Today:
    Minimum of 9.3C at 05.37 – this was the coolest night since 14th June and 0.4C below average

    Strong sun at dawn but by 06.30 cloud had drifted across giving broken sunshine. The thermometer had risen to 13.8C at 08.00

  • UV highest for 6 years

    Yesterday there were occasional bursts of sunshine, very little at the strong level. The strongest was at 12.54 when very briefly the UV level shot up to 10.4, which is at the ‘Extreme’ level and only recorded once before, in June 2011.

    The temperature edged upwards to a maximum of 21.3C with the winds a little lighter but still from a westerly direction.

    Overnight the thermometer fell to a minimum of 13.7C, which was 4C above the average, but recovered to 14.6C at 08.00.

    Yesterday:
    Maximum of 20.1 at 15.50 – down 2C on Thursday and just above average for June. We have now experienced 11 consecutive days with above average temperatures.
    Wind gust to 26mph at 12.50 – strongest for two weeks
    UV level peak at 9.0 – Very High level and highest for five days as a result of the clearer westerly air.

    Today:
    Minimum of 15.4C at 05.14 – up 3C on yesterday and almost 6C above the June average
    Humidity of 96% at 08.00 – highest since 1st June
