  • Continental air begins to make itself felt

    Thursday saw the thermometer rise to a maximum of 22.4C, the warmest day for a fortnight at 16.18 and 1.5C above the average.

    The south to south south west breeze was moderate, the day was dry and the UV level recovered to 6.4 being rated as ‘high’.

    Overnight the minimum of 10.7C was exactly same as on the previous night being 0.8C below average. However, the difference between the two following mornings was that during the early hours of Friday fog formed limiting visibility to 150m at dawn. During the next couple of hours the visibility varied as the fog bank moved around and variable cloud gave very hazy sunshine.

    The August rainfall total still stands at 78.7mm (119% of the average) with evaporation of 2 to 3mm per day now totalling 54mm.

    Update on Friday at 18.50: Continental air has arrived with the thermometer rising steadily all day to a maximum of 26.0C at 16.26. This made it the hottest day this month, the hottest day since 25th July being 5.1C above the August average. The solar strength was not particularly high, the third lowest this month, due to very thin, high cloud moderating the sun’s strength.

  • Temperature recovers

    With a maximum of 20.8C on Wednesday it was the warmest day in four days but even so just below average. The past night, with a minimum of 10.7C, was also below average (-0.8C).

    The barometric pressure continues high so it was not surprising to see the sun shining brightly on Thursday morning after dawn, with the promise of more during the day.

    The rainfall for August stands at 78.7mm but evaporation amounts to 53mm to date with the forecast of more dry days ahead.

  • Temperatures below average

    Although we had 10 hours of sunshine on Tuesday the maximum temperature of 19.4C was again below average (-1.5C).

    It was dry day, only the sixth this month, with the UV level just in the ‘high’ category.

    A very cool night followed with the thermometer falling to 7.5C, being 4C below average, at 05.38 Wednesday morning. Just after 06.30 mist briefly rolled in due to the low temperature and moist air, but this quickly disappeared by 06.45. Sun was hazy after dawn with variable cloud.

    The barometric pressure is now at its highest since 3rd July with a current reading of 1027.1mb.

  • Barometric pressure highest all month

    With rising barometric pressure on Monday there was far more sunshine, almost 10 hours, and only one very brief shower amounting to 0.4mm at 11.45. The wind was brisk from the west, gusting to 27mph, limiting the temperature to a peak of 19.2C being 1.7C below average.

    It was a cool night with the thermometer slowly falling to a minimum of 10.7C at 06.26 Tuesday, which was 0.8C below average.

    The barometric pressure has been rising for the past two days as the deep depression eased away into the North Sea, with a current reading on Tuesday at 08.00 of 1021.3mb. We therefore should have an even better day today as the sun shone brightly and continuously after dawn.

  • What’s new? – sunshine and showers

    Another cool day on Sunday starting with rain that later improved as the cloud broke up with 6.7 hours of sunshine but the maximum of 19.C was again below average (-1.4C).

    The clear skies initially overnight led to a minimum of 11.7C at 01.58 Monday morning, just above average, but increasing cloud meant that the thermometer did not fall any further with another rain shower just after 05.00.

    The rainfall total for the past twenty-four hours added another 1.8mm to the monthly total, which now stands at 78.3mm. This is 118% of the 35-year average and at the moment the wettest August since 2015 (83.1mm). The record August rainfall was set in 1992 with 139.5mm.

    By 08.00 Monday the thick cloud that brought the rain shower was easing away to the east and the cloud breaking allowing strong sunshine to break through.
