Nature Notes July 2020

Total monthly rainfall: 48 millimetres. Maximum daily rainfall: 16.5 mm (8th July). There were 11 days with total cloud-cover for at least part of the day. Maximum temperature on the hottest day was 33°C on July 31st.  Maximum temperature on the 7 coldest days was 19°C. The remaining 23 days were fairly evenly matched at between 20 and 25°C. As summer is a season of high evaporation and transpiration, the moderate rainfall proved insufficient to prevent pond-water falling to extremely low levels. Strong winds overnight on 3rd/4th July brought down a squirrel drey in a big bundle on the woodland floor. Perhaps it took revenge by strip-barking a 30 year old ash tree on the 9th.

Nature Notes June 2020

Total monthly rainfall: 34 millimetres. Maximum daily rainfall: 12.5 mm (18th June).

This mediocre rainfall left our ponds at low levels for the time of year, and our soils very dry. Measurable rain fell on 9 days of the month, and there was 100% cloud cover on at least part of 12 days during the month. Maximum temperature was 31°C on June 25th, and there were 16 days when the temperature topped 20°C, but fell to 15°C on the 4th and 15th June. Strong winds on the 5th, 6th,27th, 28th, and 29th brought down small-to-medium sized branches, including a squirrel’s drey.

Nature Notes May 2020

Total Monthly rainfall: 11.5 mm. Maximum daily rainfall: 4.5 mm (2nd May)

There was a totally inadequate rainfall during the month, resulting in low pondwater levels and very dry soils. There were only 9 days with 100% cloud cover for at least part of the day. Maximum temperature on the warmest day was 26°C on the 26th May. On the coldest day it was 11°C on the 11th May. There were 16 days when the temperature was 20°C or more. The most noticeable effects of this climate change are a large increase in the area of water lilies across the lake, and a similar increase in the number of goat willow saplings around the bank.
