18th July 2014 - High night time temperature rise

Postby Nick Gardner » 2014 Jul 18, 17:52

After slowly cooling down during the first part of the night, the temperature began to rise again and reached a peak of 22.0°C at 02:30 (see graph). This is the highest ever temperature I have recorded at that time of the night.

The high temperature corresponded to an increase in the wind speed but no rain fell at any point during the night and there was no significant shift in the general ESE to SSE wind direction.

The temperature of 22.0°C at 02:30 was warmer than the maximum day time temperature attained today (21.3°C at 14:45). Now how often does that happen in July!

Something similar happened here with the temperature rising to 21C at 0100.
It then slowly dropped to a min of 16.6C.

The high temperature was associated with a strong and gusty easterly wind.
17 knots gusting to 33 knots between midnight and 0100 BST.

Evidently, the east wind was transporting some warm land air before taking on a more southerly component which involved a track over sea.
