The daily weather log
Apart from a scarcity of rain, and an abundance of cloud, the weather in July was very much as usual. One day reached 23°, another only 12°. There were 18 frosts (normally 17), but no night was colder than -2° (normally 4 nights are). Fog filled the valley on the 28th.
There had been twenty-three days without 5 mm of rain when 9 mm fell on the 16th. In six rain days the month’s total was 21.3 mm. This is well below the median for July (35 mm): it is in the 25th percentile.
