Surfacestation: Porthmadog

Posted: April 10, 2013 by tchannon in Analysis, Surfacestation


Porthmadog, Gwynedd, Wales (actually at Morfa Bychan)

Near Harlech, Portmerion, Criccieth. Of interest is nearby a lake cooled nuclear power station which is being decommissioned. (14km north east)

52.914519° -4.158090° Bing maps, Google maps
Altitude 7 metres

Estimated Class 3, fails Class 2 on 11% trees within 30 metres, possibly Class 4 due to poor ground cover and additional scrub.

UHI, Coastal, minor local housing, distance, none.

This is a strange site which took some locating, there is no met enclosure.


Can you spot the Stevenson screen?

This image suggests a scruffy site which is not maintained, ground cover is poor and scrub is being allowed to encroach.

Site quite often figures as warmest some days when it is chilly elsewhere, (mentioned 9th April 2013) it is in a sheltered coastal area but exposed to weather from the south west. It probably is a little warm, exposure could be better.

If you use the aerial images, pull back, area has some beautiful images of the estuary sandbanks.

    I know parts of this area very well – used to go there twice a year between about 1983 and 2001, staying in Llanbedr, 5 minutes by car south of Harlech. It definitely does have its own micro-climate, being wedged being between the Rhinog mountains and the coast.

    Trawsfynydd is quite a distance away by road, being on the other side of the Rhinogs from the coast. Snowdonia is also clearly visible from Harlech. Not so familiar with Portmadoc itself (the English version of the town name).

    Portmeirion is where they filmed a famous (in the UK) TV mystery series, The Prisoner.

    ‘When he wakes, he finds himself held captive in a mysterious seaside “village” that is isolated from the mainland by mountains and sea.’

    Sorry if it’s a bit OT.
