THE BEST WAYto set it fast and precisely
Now that you have unwrapped your clock, you are just one step away from placing it in your interior : tide clock setting.
Whether you live in Paris or London, you can set your clock to either Brest's port or Brighton's. If you want, you can of course set your tide indicator to tides of another town where you are not at the moment.
To proceed to the setting, you have two choices which we are now going to explain to you. Firstly, let us start with the faster method that is both simple and optimum. This method consists of using the OCEAN CLOCK module setting which calculates the state of the tide in real time.
To enable you to set the tide indicator at anytime, we have put a free-access module on our website here. This module has been developed by Frédéric Madsen, engineer at the site Météo 56. The particularity of this setting technique is that you do not need to wait for particular conditions to make a tide clock function correctly.
In order to proceed to this setting method, all you need to do is get the necessary information to enable the module to calculate the exact position where the hand needs to be placed on the clock's face.
First of all, it is necessary to consult the tide times related to your port of reference. But where can we find these tide times ? To do so, we recommend you to visit the Marine Weather Forecast website which gives access to all the information you need in order to proceed to the setting. Afterwards, you will have to remember the date of the next new moon as well as the time of the high tide associated with that date.
Once you have collected all the required information about local tides, you may input them into the setting module. The tide clock associated with the module will show you the current position of your clock's hand. You will just need to position the hand on the same location by using the thumbwheel situated at the back of the clock and inserting the AA battery.
Here you go, it has only taken you 5 minutes to make the clock function with optimum setting. From now on, all you have to do is wait for the right time to head off to the beach.
If you are not comfortable using the online module, a more "traditional" method also exists to set your tide indicator.
To assist you throughout the different steps of this method, we have made a video that explains to you in a few points how to set your tide clock : watch it here.
Let us go over, in a few words, the different steps of the setting of the tide clock, which are presented to you in the video hereabove.
A TRADITIONAL SETTINGto adjust your clock on tide times
First of all, you need to get the tide calendar of your port of reference. If you do not possess a traditional tide calendar, you can find some online for free, on the Météo Marine website for instance.
Then, choose a day with a high tide coefficient, 85 at the minimum. But what is a tide coefficient ? It is a calculated indicator which gives the tide magnitude. It may vary between 20 and 120. We recommend you to opt for a day when the coefficient is rather high to reduce possible intervals between the clock and the real state of the tide.
How to set a tide clock accurately ? To do so, we advise you to pick a day of new moon to proceed to a very accurate setting. This way, the clock's indications will align the most closely with the tide calendar throughout the year. To find out about new-moon days, please refer to the tide calendar.
To finish, pay attention to the high sea time. You will just have to position the clock's hand on "high tide" by using the thumbwheel at the back of the clock and insert the battery.
This setting method might be inconvenient as you need to be available at a precise date and time.
The setting moment has come ! All you need to do is read the tide times on your clock before heading off to the ocean. Need help to read the tide indicator ? Visit our dedicated page now : how to read a tide clock.
Is it necessary to adjust a tide clock
Traditional clocks require a few adjustments during the year. What about tide clocks ?
You must not adjust the tide clock regularly as you may disrupt its functioning. If you notice slight intervals, you do not need to reset the tide clock as those intervals will get corrected by the next tide cycles.
However, it is recommended to proceed to a resetting after equinox periods. These periods correspond to season changes, from Winter to Spring (end of March) and from Summer to Autumn (end of September). You will have to wait for the next new moon and follow the previous instructions.
Why proceed to a resetting ? Simply because it is at equinox periods that we record the strongest tides due to the combined attractions of the Moon and Sun on the Earth and of the Sun's position relative to Ecuador. Find our article that illustrates this tide phenomenon here.
For your information, the tide clock does not need to be adjusted when time changes, in Summer and Winter. Indeed, those changes have no impact on solar or lunar cycles and thus they do not impact tides.
Mais pourquoi procéder à un nouveau réglage ? C’est tout simplement aux périodes d’équinoxes que l’on enregistre les plus fortes marées en raison des attractions combinées de la Lune et du Soleil sur la Terre et de la position du Soleil par rapport à l’Equateur. Retrouvez notre article expliquant le phénomène des marées ici.
Pour information, aucun réglage pendule des marées n’est nécessaire lors du changement d’heure, été comme hiver. En effet, ces changements n’ont aucun impact sur le cycle lunaire ou solaire et donc aucun sur les marées.
