Windrush Weather

Author: Eric Gilbert

  • Wettest day for six weeks

    Friday started with strong sunshine that was obscured just before midday as the shower clouds began to build. The sunshine lasted for just 2.09 hours, the lowest daily amount this month as was the UV at 4.9 being in the Moderate level. The peak temperature was 22.9C, just above average.

    A few spots of rain were noted at 14.00, which amounted to just dampness on the ground and soon dried up. However, a shower started at 14.50 with steady light to moderate rain that lasted for over two hours, very light for the last half hour, and totalled 4.0mm, which made it the wettest day since 31st May. Unlike other areas we did not experience the downpours that were to the east and west of Marlborough. During the period from 15.32 to 16.24 eight claps of thunder were heard.

    It was a cool night with the thermometer falling to 11.2C, just 0.5C below the average.

    Saturday arrived with fog, which after dawn limited the visibility to 200m, that cleared by 07.30 as the thermometer recovered to 15.8C at 08.00.

  • Evaporation almost equals monthly rainfall – BUT we have only had just one brief shower!

    It was another dry day and the UV again into the Very High level

    Update at 18.16: rainfall to 18.00 was 4mm, being the wettest day for six weeks from steady, light rain. No downpour but welcome rain without damage. During the showers eight claps of thunder were heard. Currently weak sunshine breaking through.

    Wednesday dawned with sunshine but by 06.30 cloud had arrived from the North Sea blotting out the sun, which meant the thermometer only recovered to 13.4C at 08.00. This was 6 to 7C below the warmest mornings this month.
