The last few of my posts to this thread was comparing my temperature figure on the car in driving mode not when it was stationary for a while with a hot engine affecting the thermometer. Yesterday evening I was passing near Shannon shortly after 7 pm. It was 22c on the car. The Airport station reported 21c at 1900 and 2000. Therefore I am not buying in that the weather station more or less surrounded by car parks has a major effect on how it records the temperature at any given time.
