  • Cooler again, especially at night

    With a maximum of only 10.1C (-3.9C) and a minimum of -1.3C (-5.3C) both day and night were significantly below average as regards temperature. However, the many hours of sunshine made Saturday a pleasant day if feeling cool in the strong breeze, which had veered into the east.

    Sunday saw brought sunshine strongly after dawn in almost still conditions at 08.00 with the thermometer having risen to 2.6C after the sharp air frost.

  • Cool, very cool!

    Friday was another below average day with a maximum of only 10.4C being 3.6C below average. The following night was also below average with a minimum of 0.9C (-3C).

    Saturday arrived with strong sunshine from dawn lifting the temperature to 3.9C at 08.00 under the influence of the anticyclone centred over Scandinavia producing a brief ground frost but not air frost.

  • Sharper air frost after many hours of sunshine

    The lighter breeze from the Northeast and nearly ten hours of sunshine lifted the temperature a little higher than previous days but with a maximum of 11.C was still 2.1C below the average.

    The UV level was again in the ‘moderate’ category.

    It was a dry day with the monthly rainfall total standing at 32.0mm but with drying winds and much sunshine the evaporation from ground sources and plant life has increased with the equivalent rainfall of 2.75mm ad 2.91mm lost to the atmosphere over the last two days.

    A sharper air frost than the previous night occurred with a minimum of -1.6C, which was 5.7C below the average for April.

  • Air frost returns

    Wednesday brought us many hours of sunshine although a brisk northeasterly breeze, maximum 24mph, suppressed the temperature by day with a maximum of 11.7C. This peak was up over 2C on the Tuesday maximum but still 2.3C below average with a wind chill that meant it felt a couple of degrees cooler. It was a dry day with the UV level returning to the high end of the ‘moderate’ level.

    Not surprisingly, with clear skies overnight, the temperature fell away producing an air frost with a minimum of -0.7C at 06.27 this morning, Thursday.

    Thursday saw the sun shining strongly as it rose above the horizon that by 0800 had lifted the temperature to 2.1C with just minimal movement of the air.

    This change in weather is due to an anticyclone over Scandinavia with the consequent high pressure bringing a dry and more settled few days, with sunshine.

  • Lowest solar energy for a month

    Tuesday was a gloomy, wet and miserable day with very low cloud persisting all day and occasional light rain showers amounting to 2.7mm. The soar energy was the wets since 12th March.

    The temperatures by day and night were suppressed thanks to the cool air flow from the north east. The maximum was only 9.1C being 4.9C below the 35-year average and the minimum at 01.36 this morning was 4.0C, which was 0.1C below average. Both were 3C down on the Monday highs.

    Wednesday arrived with the persistant rain band from yesterday now over the south coast resulting in thinner cloud and a much higher base. The wind, gusting to 22mph from the north east is producing a wind chill so that at 08.00 the thermometer read 4.3C but it felt more like 2C.
