Windrush Weather

Author: Eric Gilbert

  • What a difference a change in wind direction makes!

    Wednesday saw a change in direction of the wind. After 10 days of persistent northeasterly winds, they now came predominantly from the south. It brought a milder and less dry atmosphere.

    The sunshine yesterday, amounting to 3.7 hours, raised the temperature above the average reaching a peak of 21.9C, being 2C above the 34-year average.

    However, from early afternoon, the fall in barometric pressure as storm Hector approached the UK, meant that the next weather front showed its hand as variable cloud began to filter across the sky and reduce sunshine.

    It was a mild night with the minimum temperature of 13.0C, which was 3C above the average for June.

    Thursday arrived with light drizzle beginning to fall at 06.40 amounting to 0.3mm by the time readings were taken at 0800. The wind strength has been increasing for the past four hours with a peak gust of 26mph at 07.10.

  • Coldest night for almost a month

    Tuesday morning was initially overcast with occasional light drizzle, not measurable, but brightened towards late morning with just 1.3 hours of sunshine in the afternoon.

    As a result the temperature was down almost 6C on the very warm Monday with a maximum 1C below average rising to 18.7C.

    The sky cleared in the evening giving a pleasant end to the day but the clear skies gave us the coldest night since 21st May with a minimum of 5.7C at 04.51 this morning.

    Wednesday arrived with intermittent sunshine that lifted the temperature to 13.0C at the time readings were taken at 08.00.

    Update at 12.00: at last the wind this morning has changed from the persistent north east direction now varying between south and west and light in strength.

  • Temperature soars on Monday but change on the way

    Monday gave us 14.28 hours of glorious, strong sunshine that boosted the temperature to a maximum of 24.3C, which was 4.3C above the June average.

    Peak UV level again reached the ‘Very High’ level.

    Overnight, the same story as on many previous occasions this month, as cloud drifted in from the nornoreast so that it gave another mild night with the thermometer falling no lower than 10.9C.

    Tuesday at dawn arrived with brief brightness but thick cloud soon dominated the sky. The wind today has backed a few degrees and is coming from a more northerly direction.

  • Litte variation in barometric pressure over 10 days

    Sunday was another day that started misty but by midday the sky was begin to clear and 6.3 hours of sunshine followed with the UV level into the ‘Very High’ level.

    With the strong sunshine the thermometer rose to a peak of 22.6C, being 2.6C above the 34-year average and up 2C on the Saturday maximum.

    It was another dry day with evaporation from ground sources and plant life giving the equivalent loss of rainfall of 28mm when actual rainfall in June has only been 2mm.

    A slightly cooler night followed under mainly clear skies allowing the thermometer fo fall away to a minimum of 10.7C, still just above average.

    On Monday morning the lower temperature and lack of wind in the early hours allowed fog to form with visibility down to 200m at 06.00. This began to thin around 7am with the sun breaking though at 07.47 that lifted the temperature at 08.00 to 14.1C.

    Monday update at 17.30: 2nd warmest day in June with a maximum of 24.3C at 16.47, being 4.2C above the 34-year June average. UV Very High again.

    Signs of the blocking ‘High’ sliding away, which indicates a change, later in the week, from the settled weather of recent days.

  • UV at ‘Very High’ level again on Saturday

    After a cool, misty start on Saturday the afternoon brightened up with 3 hours of strong sunshine and the UV level back up to the ‘Very High’ level. As a result the maximum temperature eased up on Friday’s maximum to a peak of 20.7 mid-afternoon at 14.39, just above average.

    Subsequently, a weak weather front edged up from the south with thickening cloud so that at 17.10 there were heavy spots of rain and again at 18.05 but not sufficient to measure.

    Late evening the sky began to clear and weak sunshine broke through.

    Another mild night followed when the thermometer reached a minimum of 11.2C just before 4am being 1.2C above the 34-year average.

    Sunday arrived with misty conditions but by the time readings were taken at 08.00, the cloud had lifted just a little, the thermometer had recovered to 13.7C but no sunshine,

    Sunday update at 18.30: UV soars to ‘Very High’ level in afternoon as temperature rises to 22.6C at 17.27,which was 2.6C above the 34-year average.
