Windrush Weather

Category: Commentary

  • Temperatures cover but both still below average

    Although the maximum of 16.9C was nearly 4C above the cold and damp peak on Friday it was 0.2C below average. A notable feature of Saturday was the lack of wind, for many periods the anemometer was still. The strongest movement of air from the north east, cannot call it a gust, was just 8mph.

    The thermometer fell below average overnight with a minimum of 5.6C at 05.26 (-1.5C).

    Sunday saw weak sushine after dawn with again little wind.

  • A very cool and depressing day

    Friday saw the maximum below average again by a significant 4C with a peak of only 13.1C. With a brisk wind from the northeast, gusting to 16mph, there was a wind chill that meant at times it felt 2C bellow the temperature shown on the thermometer.

    There were several very light drizzle showers that emanated from the thick cloud cover, but nothing was measurable hence ‘trace’ shown in the records.

    By contrast, due to the thick cloud cover overnight, it was the first above average minimum in ten days with the thermometer not falling below 8.9C making it the warmest night this month.

    Saturday arrived with the persistent thick cloud although the cloud base at 08.00 was higher than on Friday with the thermometer at that time reading 10.1C and virtually now wind.

  • Cooling off!

    Although we had 10.7 hours of sunshine on Thursday it was a cooler day than Wednesday with a maximum of 18.8C, which was 1C above average. The brisk wind, then veered into the Northeast, and reduced solar energy due to thin high cloud, moderated the temperature.

    It was a dry day and UV level at the top end of ‘high’.

    Initially overnight the thermometer fell away to a minimum of 6.7C at 03.25 but increasing cloud brought on the north east wind meant a recovery to 9.4C at 08.00 on Friday norming.

    Thick cloud Friday morning meant the first day this week when we were not greeted by sunshine at dawn. A rain band passed over the area between 06.00 and 06.45 that produced a few drops of rain but insufficient to measure thus recorded as a ‘trace’.

  • Thermometer climbs a little higher

    Wednesday saw the thermometer reach a peak of 19.8C (2.7C above average), the warmest day this month, under the influence of the high pressure, new easing away, and gave us another sunny day (11.8 hours).

    The blocking high meant any rain bands were kept way-out to the west although during the afternoon, thin cloud drifted across on the easterly breeze.

    Another cool night was to follow as the thermometer fell away steadily to a minimum of 3.3C (3.8C below average) at 05.44 Thursday morning. Only two days this month have seen the minimum temperature above average.

    Dawn on Thursday saw the sun shining, if a little hazy with a brisk, cool easterly breeze.

  • Warmest day this month

    On Tuesday the almost continuous sunshine totalling 12.4 hours, raised the temperature to a maximum of 18.6C, which was 1.5C above average and the warmest day this month.

    As the barometric pressure falls, 12 mb over the past two days, the pressure gradient increases hence the increase in the strength of the breeze with a modest gust of 18mph yesterday.

    Tuesday saw the UV level rise to 6.9, which was on the border of the ‘very high’ category.

    Although the minimum overnight was still below the average (-2.8C) it was less cold than the three previous nights with a low of 4.3C.

    Update on Wednesday at 21.50: thermometer rose to a maximum of 19.8C at 15.41, which was 2.7C above average.
