The maximum of 17.2C on Monday was 1.5C below average and the coolest day since 31st August as a result of the cold front bringing a much cooler air stream. The warm air from the Azores is just a memory from last week.
We enjoyed the sunshine between the showers, which at times were heavy with a daily total of 4.3mm.
The past night was also cool with a minimum of 8.2C being 0.9C below average.
Tuesday dawned with rain from a totally cloudy sky, not from showers as on Monday.
The very warm sunshine on Sunday, totalling 6.7 hours, saw the thermometer rise to 22.1C being 3.4C above average as the drift of warm air from the Azores continued.
The warm air was present overnight with the thermometer not dropping below 15.9C until the arrival of the the cold front. This brought a little rain at 02.00 but the main rain band arrived minutes after 05.00 for 2.5 hours, very heavy at 07.05. The rainfall amounted to 10.7mm bringing the monthly total to 33.7mm. As the back edge of the cold front cleared to the east, bringing clear skies, the thermometer promptly dropped 4C and the wind veered into the west.
Due to the many dry, warm days there has been an equivalent loss of 44mm of rainfall due to evaporation from the ground and plant life.
The minimal wind speeds we have seen all week continued on Saturday with a peak gust of just 13mph.The sunshine was minimal at 0.8 hours with the temperature down on the high of Friday with a maximum of 19.8C, which was 1.1C above the 37-year average.
There were a few spots of rain at 16.35, more to the south of Marlborough.
Another mild night with the lowest temperature at 12.8C being 3.7C above the average.
Sunday arrived with variable fog from 400m to 1500m but by 08.00 it had all but evaporated.
The weather is on the change with the barometric pressure having fallen steadily over the past six days from 1032mb to 1011mb at 08.00.
The temperature rose to a peak 23.4C on Friday, which was 4.7C above hate average and making it the warmest day since the 8th (28.2C).
The viable wind, manly frpn the west was light with a peak gust of 13mph.
A very mild night followed with the thermometer not sinking below 15.4C, whucwas 6.3c=C above average and the warmest night since the 10th (15.9C).
Sadly no sun after dawn with total cloud cover and fog observed the higher ground to the north.
After a calm night, when the wind dropped out entirely, I discovered that gossamer thread had locked up the higher anemometer. A five meter telescopic fibre glass pole enabled me to free the instrument.The 5.3 hours of sunshine lifted the temperature to 23.6C being 4.9C above average and the warmest day since 8th (28.3C).
The minimum overnight was 10.2C being 1.1C above average due to the persistent cloud cover that thickened as the next weather front arrived and deposited 0.2mm of rain just after 05.00.
Monday dawned with thick cloud and another rain band threatening from the west.
