MM Met office had it spot on. Quote Link to comment Share on other sites More sharing options...

My weather station (which is a pretty old 'cheap and cheerful' one) has a facility to correct the barometer reading (to allow for location above sea level). May be worth looking on line for a manual for yours if you don't have one. Most analogue barometers have a screw at the back to adjust for altitude.

Most analogue barometers have a screw at the back to adjust for altitude. i believe the met office air pressure value is issued at sea level.....i check mine and adjust the screw...and give it a tap... im about 4 metres above sea level here....and my machine is not a Barometer..its an altimeter..Sundo-Alpina (W.Germany)..hand held...........its what i used when surveying for roads in the mountains of S.
