3rd July 2016 - A Return of the Sea Breeze

Post by Nicholas Gardner » Sun Jul 03, 2016 6:38 pm

After what seems like a summer so far without sea breezes, they made a dramatic and much appreciated come back today.

A generally cloudy morning though at times the sun could be glimpsed, barely any wind to speak of and it was variable in direction. Then at just after 13:00 a wind picked up from the south heralding the start of the sea breeze. You hear the sea breeze before it arrives from the sound of the wind rustling the leaves of the oak trees as it moves up the valley. The way how the sky cleared abruptly from the south 'pushing' all the cloud inland leaving us in scorching sunshine with a pristine, dark blue sky and high UV levels was inspiring and reinforces why I am fascinated by them.

As it was a cloudy morning the sea breeze did not bring a drop in temperature but through the afternoon the persistent 8 mph breeze kept the temperature pegged back to 20.6°C with a DP between 15°C & 16°C. A notable feature of the sea breeze here is that as the summer progresses the breeze's ability to reduce temperature and humidity decreases and from mid-August onwards it can often bring warmer, more humid conditions.

The satellite photo below is from from Bernard Burton's excellent website: http://www.woksat.info and was taken this afternoon at 14:35. It shows a convergence line across the SW peninsula and the prevailing WNW wind pushing that convergence line towards the south coast winning out against the weaker sea breeze moving up from the south.
