Black Coastal home set. Comprising black Tidal Clock and combined Barometer/Thermometer/Hygrometer. All you need for monitoring conditions within the home and outside! The Thermometer and Hygrometer allows you to monitor temperature and humidity level within the home to make it as healthy and comfortable as possible. The Barometer allows you to plan outside activities. The Tidal Clock is perfect for planning beach activities. Bulkhead design adds a nautical feel. Mounted on solid ash wood.
Barometers make useful gifts for anyone involved in outdoor activities and Tidal Clock will predict the high and low tides of the area you are monitoring. The perfect coastal home set of instruments.
Barometers read the pressure of the immediate location where placed. It will advise you of what weather to expect in the next 12 – 24 hours
How to ready your barometer: The chrome pointer in the glass should be turned so that it rests directly above the black barometer pointer. The chrome 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 and how significant a rise or fall in pressure has occurred. A rapid increase in pressure indicates a short period of good weather and a fast decrease indicates storms and strong winds approaching.
A slow, constant increase in pressure indicates a period of settled, dry, sunny weather, whereas a steady decrease indicates persistent bad weather.
If the pressure falls considerably below 1000 millibars, you can expect storms and strong winds.
Tidal Clock will predict the average state of the tide once it has been correctly set.
It must be stressed that other influencing factors such as storms, high or low surface pressure and direction can affect the actual tide times.
Full instructions will be provided to set and use your clock. Battery driven which is provided. Please use good quality alkaline batteries and replace every 12 months to avoid battery leakage. We recommend Super Alkaline 1.5V GP Battery – we do NOT recommend the use of rechargeable batteries.
The primary controller of the tides is the moon. The average duration between two transits of the moon around the earth is 24 hours 50 minutes and 30 seconds – this is referred to as the lunar or tidal day. It means the tidal day – to which the tide indicating hand is geared – is 50 minutes and 30 seconds longer than the solar day of 24 hours.
The west coasts of Europe and Africa and the east coasts of North and South America follow the semi-diurnal pattern of two high and two low tides each day, more or less equally spaced, so your tidal clock can be used. However certain others coasts such as the west coasts of North and South America are not semi-diurnal, therefore the tide indicating part of your tidal clock will not function in these areas
