Thursday gave us the greatest solar energy this year, but it is almost the longest day, with wall to wall sunshine. As a result the thermometer reached 27.1C, being 6.9C above the 39-year average, and the fourth above 27C for the heatwave threshold.
The last night has been warm with a low of 12.3C, which was 2.1C above the average.
The loss again of over 5mm daily of equivalent rainfall was not surprising due to the heat and drying breeze. We have no lot 57.9mm of equivalent rainfall due to evaporation from ground sources and plant life when the rainfall has been just 14.8mm.
Friday revealed some high thin cloud that meant the sunshine was a little weaker. This is ahead of a depression edging in from the west and heralds a significant change in our weather for the next few days. The extreme heat will be no longer after today but replaced with lower temperatures and more cloud with the possibility of modest rainfall.
The temperature at 08.00 was 20.0C making it the warmest start to a day at that time since 12th August. The air movement is now from the east and likely to veer from the southeast, a direction not seen for a month.
