How to set a barometer?

Just like a tide clock, a barometer requires specific manipulation to be set correctly.

Here, we will give you the details on how to set a barometer in a few steps so you may forecast today’s weather from your home.


Setting the barometerin 2 steps

You just got yourself a barometer and you cannot wait to make it work and be able to forecast the weather.

To do so, you must follow the 2 following steps to proceed to the setting of your barometer.


To calibrate your handed barometer, you need essential data to set your barometer: atmospheric pressure, expressed in hectopascal (hPa).

This pressure varies with altitude and weather events, it is thus essential to find the exact pressure of your location.

How to know my town’s atmospheric pressure?

To find this information, all you need to do is consult the weather forecasts of the place where you live, by consulting the website As pressure varies from a few hectopascals every hour, it is better to set your weather barometer according to the pressure of the setting time.

The website will locates you and gives you in real time the atmospheric pressure of your town.


After you figured out what the current atmospheric pressure is where you live, you may proceed to the setting of the aneroid barometer.

Do not be surprised if you cannot find a setting thumbwheel at the back of the wood barometer, as you may find on clocks. But then, how to set a barometer?

It is all very simple! You need to position the hand on the value corresponding to the pressure you checked earlier. To do so, you will find at the back of the barometer a setting screw that you will have to turn until you reach the right graduation. To do so, use the little screwdriver supplied with your Ocean Clock barometer.

As its mechanism is very sensitive, we advise you to HOLD YOUR BAROMETER VERTICALLY and to SLIGHTLY TURN the setting screw and then tap on the glass to unblock the hand. Do so until you reach the required value.

As soon as you calibrated your barometer, all is left to do is place it and check it every day to make your weather forecast for the next 12 to 24 hours.

Where to placethe barometer?

Once the handed barometer is set, you may place it at the heart of your deco.

So you may properly use your barometer and for as long as possible, we recommend you place it in a spot where it will not be subject to hot temperatures, rain or violent storms, as they would distort its indications and damage your wood barometer with time.

For all those reasons, it is better to suspend it inside your house on a wall where it is protected from the sun and winds. Indeed, avoid placing it outside or in areas where temperature varies a lot like in bathrooms or near a source of heat like radiators.

As its hand possesses a counterweight, it is essential you suspend it vertically to avoid distorting the barometer’s indications.

Once you have found the perfect spot where to put it, all that is left to do is to suspend your lovely deco barometer on a wall thanks to its hanging hardware.


Do we need to set the barometerregularly?

Our stylish barometer only needs to be calibrated once, therefore you will not have to set it again any more.

Each day, you will just have to position your reference pointer on the weather barometer’s hand and tap with your finger on your barometer’s glass face.

Why? As the atmospheric pressure changes regularly, this manipulation will allow you to see the pressure variation thanks to the hand’s movement. The hand’s new position compared to your reference pointer’s position will give you an indication about the weather forecast.

Keep in mind though that it is essential to proceed to a recalibration of the aneroid barometer if you change locations. In this case, you will have to go through all the setting steps again, but this time you need to use the atmospheric data related to your new location.
