Trearddur Bay Weather Station – Part 2

It’s been a couple of weeks since I first mentioned my weather station project in this forum so I thought it would be good to provide you with an update on how things are going.

I spent some time at Eithin Bach last week in the midst of the Beast from the East which allowed me to make generally good progress across the board.

Over the past two weeks:

  • Phase 2 – Installation:  Has progressed to the extent that most of the bits, including the stainless steel mounting pipe, have now been sourced so I am optimistic that the weather station should be flying high above Eithin Bach shortly after Easter once the detailed plans have been agreed with Chris.
  • Phase 3 – Website:  Has progressed well and there is now a purpose-built website in operation that can be found at weather.trearddurbay.org.  The content is still not fully available, nor will it be until Phase 2 is complete.  However, the website is updated every minute, so as soon as the weather station has been mounted externally, everything should start flowing through automatically.

There are a few technical glitches that need to be ironed out to make the system sufficiently robust.

For example, for those technically-minded people, BT do not provide static IP addresses to residential customers which means that the public address of the weather station changes from time to time.  Since the server that posts (by SFTP) the website updates to the site is based in London, this means that the service goes offline every time BT change the weather station’s IP address.

Second, I am conscious that the website updates automatically every minute and it may be helpful to pause this so that people reading the site may peruse some of the data at their leisure.  I’ll work on this in due course but it is not a priority at this time.

The final part of this post is to provide an update on the Davis Weatherlink service, namely:

  • The name of the weather station has been changed to Trearddur Bay.
  • The granularity of data posted to Weatherlink is now every minute.
  • However, the data is only transferred from the weather station to the Davis site every thirty minutes and there is additional latency in the service which makes the site of limited use for sailors.
  • The Davis service is also available as an app for Apple and Android phones.

That’s it for now.
