Windrush Weather

Author: Eric Gilbert

  • Sharp frost follows wall to wall sunshine.

    Sunday saw the sun shine continuously from dawn to dusk logging 9.61 hours. The very mid air, then from the south east, lifted the temperature to a maximum of 15.6C, which was a significant 8.5C above the 35-year average and more representative of average April temperatures.

    The anticyclone intensified producing very still air conditions with the maximum gust, if it can be called that, of just 9mph.

    With clear skies overnight the thermometer steadily fell to a minimum of -1.6C at 05.00 this morning, Monday, which lifted the temperature to 1.2C at 08.00 as the sun got to work when it rose above the horizon.

    The barometric pressure has continued to rise with a reading of 1036.1mb at 08.00, Monday morning, the highest pressure for over a month.

    Update on Monday at 15.10: 35 year record broken as warmth increased again with a maximum of 17.7C at 14.46, which was a significant 10.6C above average making it the warmest day since 21st October. The previous record was set on 14th February 1998.

  • Warmest day in four months

    With very light air movement from the south and 7.84 hours of sunshine, the thermometer rose to a maximum of 15.8C on Saturday. This was a significant 8.4C above average and the warmest day since 21st October.

    With no further rain the total for February still stands at 61.4mm, just 3.5mm short of the 35-year average.

    With clear skies overnight it was not surprising to watch the temperature slowly fall during the evening and to find the minimum of -0.2C was set at 07.30 this morning, Sunday. This low was 1.2C below average.

    Sunday morning saw the sun shine brightly as soon as it got up, that by 08.00 lifted the temperature above freezing with a reading of 0.9C.

    Update on Sunday at 17.20: another unusually warm February day with a maximum of 15.6C being 8.5C above average in calm conditions with the strongest air movement all day reaching just 9mph.

  • Dense early morning fog again

    After a foggy start, with visibility reduced to 200m, the sun began to break through late morning to give us 6.76 hours of sunshine. Due to the late arrival of full sunshine and the shift in wind direction into the south east, the maximum temperature of 11.4C was lower than that on Thursday but still 4.3C above the average.

    The barometric pressure was at its highest for a month with a peak reading of 1035.0mb. This anticyclone means a slack pressure gradient thus little wind to break up the fog and cloud but also gives a lower temperature by night. The UV level, with a reading of 2.1, was the strongest since 21st October.

    The clear skies during the last night and still wind conditions meant that the thermometer steadily fell away to a minimum 2.7C at 07.21 this morning, Saturday.

    Saturday morning arrived with dense fog, with initial visibility below 100m.

    Update on Saturday at 15.45: thermometer soared to a maximum of 15.8C at 14.55 being 8.7C above average. Warmest day since 21st October.

  • Fog returns after warm day.

    Thursday saw the thermometer rise higher again to a maximum of 13.2C at 12.59, which was a significant 6.1C above the 35-year February average.

    Another 6.36 hours of sunshine was recorded with the UV level again the highest since October at 1.9.

    Fog formed overnight as the temperature dropped to 5.9C at 07.12 this morning limiting visibility to 200m.

    Friday morning at sunrise time, saw the fog ease from 100m to 200m but then little improvement in visibility in still air conditions.

    Update on Friday at 15.20: although still above average, a slightly cooler day with a maximum of 11.4C (+4.3C) at 14.43 under light winds now backed into the south east.

  • Highest UV light for four months on Wednesday as the sun gets stronger

    There was limited sunshine on Wednesday, just 5 hours, but the flow of southerly air from mid Atlantic around the Canary Islands meant the thermometer eased upwards again to a maximum 11.5C, which was 4.4C above average.

    It was another dry day with the UV level rising to 1.9, the strongest since 24th October.

    The thick cloud and southerly air flow meant a very mild night with the thermometer not falling below 7.8C, which was a significant 6.5C above average for February.

    Thursday morning saw thick cloud and light winds with the southerly air flow continuing, the thermometer having risen to 9.3C at 08.00, which was already 2.2C above the average daily maximum.

    Update on Thursday at 15.40: warmer again with a maximum of 13.2C at 12.59, which was 6.1C above average, making it the warmest day in three months.
