Windrush Weather

Author: Eric Gilbert

  • Barometric pressure continues to build

    Although the maximum for Monday was a little higher than on Sunday at 11.9C, it was still 2.8C bellow the 35-year average due to the breeze from the north, which was also little stronger gusting to 17mph.

    However, it was a drier air on Monday that meant it was only the third dry in October.

    The past night was also below average with a minimum at 08.35 today of 3.2C, which was exactly 4C below the average.

    Tuesday arrived with broken cloud and some brightness. The barometric pressure at 08.00 read 1023.5mb, the highest pressure since 20th September.

  • Northerly breeze meant coolest day in six months

    The wind, having veered into the north on Sunday, meant temperatures by day were depressed with a maximum of 10.7C, being almost 4C below average. This made it the coolest day since 14th April. The minimum was 8.7C, which was 1.5C above average due to the cloud cover restricting heat loss into the atmosphere.

    There was a light shower overnight amounting to 0.3mm that brought the monthly total to 124.3mm, which is 40mm above the 35-year average.

    Monday arrived with total cloud cover due to a minor weather disturbance to the south east.

  • Only second dry day in October

    With the barometric pressure rising for the past twenty-four hours, as the depression eased away, it was not surprising to find a change in the unsettled weather of the last two weeks. It was a dry day, only the second this month, the only other dry day occurred on the 2nd.

    Significantly, the high pressures easing in from the west has meant a change in wind direction, now coming from the north bringing the cooler air.

    The sunshine daily total rose higher than the Friday figure with almost 5.9 hours, the UV level again in the ‘low’ category.

    With clear skies overnight the thermometer fell away sadly to a minimum of 1.5C at 03.29 Sunday morning, which was 5.7C below average.

    Sunday saw broken cloud and the thermometer recover to 4.3C at 8.00.

  • Almost a dry day on Friday!

    With just a light shower amounting to 0.3mm, Friday was predominately dry. There was more welcome sunshine totalling 4.8 hours although the UV level was ‘low’ as expected in the late autumn.

    The maximum by day was 14.1C, just below average whereas the minimum overnight, occurring at dawn on Saturday, was just below average at 7.6C.

    Saturday saw the sun shine in a clear sky as it rose above the horizon with the promise of more throughout the day as the barometric pressure is beginning to rise again with the low-pressure system easing away.

  • Conveyor belt of showers continues

    Thursday brought further light showers by day but much heaver overnight with a daily total of 8.1mm. Thus brought the monthly total to 123.7mm, which is 148% of the 35-year average.

    Temperatures by day were just below average at 13.2C (-1.5C) but above by night at 7.6C (+0.4C)

    Friday saw some brightness after dawn with variable cloud and the barometric pressure at its lowest this month with a reading of 996.8mb as another low pressure system approaches the UK.
