Temperatures were consistently being recorded about 6-8C above what they
should have been due to reflected sun radiation from the concrete patio
below the sensor for two hours each afternoon. This in the process of being
cured.
On 23rd May, Pitsford recorded a high of 26.7C, the highest for the month.

2 cases of birds landing on the rain sensor resulted in an over read of 3mm
(0.6 & 2.4). This is also being cured.
