Perfect gift for anyone needing to know what the weather has in store: farmers, golfers, gardeners, equestrian even dog walkers and doing the washing!
It should be understood that the barometer forecasts conditions 12 to 24 hours ahead. The gold pointer in the barometer glass should be turned so that it rests above the black pointer. The gold pointer acts as a marker enabling you to remember today’s pressure when you next look at your barometer. You can thus see whether the pressure is rising or falling.
With air pressure at 1020 millibars or higher you can expect calm, dry weather. The higher the pressure, the more settled the weather. Fair weather in summer and clear, cold weather in winter, but with the possibility of fog.
When the pressure is between 1005 and 1020 millibars, the weather is changeable, short bright spells and showers. When the pressure is below 1000 millibars, the sky is mostly cloudy with a tendency towards rain.
If the pressure falls considerably below 1000 millibars you can expect storms and strong winds.
A slow, constant increase in pressure indicates a period of settled dry sunny weather, whereas a steady decrease indicates persistent bad weather. A rapid increase in pressure indicates a short period of good weather and a fast decrease indicates sotrms and strong winds. In summer a rapid decrease can mean the approach of thunderstorms.
