Nature Notes August 2019

Total monthly rainfall: 44.5 millimetres. Maximum daily rainfall: 10.5 millimetres (9th August). There were 14 days with measurable rainfall, and only 6 days with 100% cloud-cover for at least part of the day. Maximum temperature on the warmest days was 31°C on August 25th, 26th, and 27th. On the coldest days it was 17°C on the 10th and 14th of August. Temperatures were below 20°C between the 10th and 20th, except on the 17th and 18th, when the temperature reached 20 degrees. This gave an autumnal edge to the month, accentuated by the strong winds on the 10th. We calculate these to be force 6, gusting force 8, and resulted in bringing down a large goat willow by the lake, and a wild hop and trellis by the front corner of the house – together with many leaves and small branches in the wood.

Strong winds on the 30th-31st removed many small branches, twigs and green leaves from the trees.

Total monthly rainfall: 102 millimetres. Maximum daily rainfall: 28.5 millimetres (10th June).

Nature Notes May 2019

Total monthly rainfall: 29 millimetres. Maximum daily rainfall: 12.5 millimetres (7th May).

Another month of low rainfall, with measurable rain falling on only 8 days, resulting in pond levels already over 30 centimetres below maximum.

Maximum temperature on the warmest days reached 22°C on May 23rd and 30th, while maximum temperature on the coldest day was 10°C on the 4th. Although there were only 13 days with full cloud-cover, there were 16 days when a stiff breeze from the north-west and north-east caused unpleasant flying conditions for dragonflies, butterflies, and moths.
