During periods of really high (anticyclonic) air pressure, we occasionally see the clocks at the workshop and BB HQ skip between ‘Very Dry’ and ‘Rain’. This can, naturally, cause concern when it’s dry outside and it says ‘Rain’ or vice versa. We can reassure you, though, that this slightly unusual behaviour doesn’t mean that your clock has lost its marbles!
The clocks are generally a little happier (and more accurate) in more ‘normal’ or mid-range air pressure periods. You could say that in typical British Bank Holiday weather style, the clocks are a little more pessimistic or worrisome than they should be! If the air pressure is high, they are sensitive to even the slightest dip in this pressure, causing them to say ‘Rain’ when there’s no precipitation to be seen. And, indeed, when on the rare occasion it rains during periods of high pressure, the clocks can skip back to ‘Very Dry’ a little too soon!
