The Partial Sun Eclipse of this Saturday, March 29 promises a grand spectacle in the sky of France, provided that the weather is at the rendezvous. Hours, concealment rate, observation conditions, all practical information.
The solar eclipse of this Saturday, March 29, 2025 is a rare spectacle not to be missed in the sky of France. The phenomenon will be partially visible from all regions of France between 11 a.m. and 1 p.m. approximately. If the time of observation and the concealment rate of the Sun By the moon differs according to the city where you will find yourself, it is important to note that what you will see will depend on the weather.
Fortunately, the weather conditions promote favorable to the northwest of the country, where the partial eclipse will be the most visible, with the surface of the sun hidden 32.5% in Brest at 11:55 am at the maximum of the eclipse, from 25% in Lille at 12:06 and 23.5% in Paris at 12:03 p.m. Thanks to the Mistral, the sky will be relatively cleared in the south with good observation conditions in Marseille which will see the sun nibbled by the moon up to 11.7% at 11:57 am. The weather conditions will however be more unfavorable in the cities of eastern France with significant cloud coverage.
It will be imperative to wear special glasses to observe the solar eclipse. Where to get this equipment? What is the percentage of occultation and the observation schedule according to the City of France where you are? How to explain the solar eclipse phenomenon? We tell you everything.
17:25 – Here is the place where we will best see the solar eclipse in France
Some regions will be more advantaged than others to observe the partial solar eclipse of this Saturday, March 29, 2025. The more west of France will be found, the better the observation. It is therefore in Brest, as was the case for the previous lunar eclipse, that the show will be the greatest. The Brestois will indeed have the chance to observe almost a third of the sun hidden by the Moon! The icing on the cake, Météo France announces beautiful clearings at the time of observation of the eclipse, that is to say between 10:57 am and 12:52 am, with a maximum of the eclipse provided for at 11:55 am.
16:50 – What is a partial solar eclipse?
A partial eclipse of the sun takes place when the alignment earth-moon-sun is not perfect, when the moon passes slightly above or below the alignment-sun. The moon only hides a piece of the sun, which is not enough to completely darken the sky. “To start having a feeling of darkness in the sky, to perceive a kind of cold light, it takes at least 95% obscuration of the sun,” said Florent Deleflie, astronomer at the Paris Observatory. This astronomical phenomenon of partial sun eclipse, which occurs when the sun, the moon and the earth are imperfectly aligned, does not assist the sky and is observable that with adequate protections, under penalty of “irreversible retinal burns”, warns Florent Deleflie, of the Paris Observatory.
16:20 – At what time to see the solar eclipse of March 29 according to your city?
The Sun Eclipse of March 29, 2025 will be visible in France partially, masking only 9.9 % of the surface of the sun in Nice while in Brest, the surface will be covered by 32.5 %. Here is the percentage of concealment of the solar eclipse according to the city where you will find yourself (IMCCE data) as well as the observation schedule when the eclipse is at its maximum:
- Paris : 23.5% obscure by the moon with a maximum at 12:03 pm (Paris time).
- Brest : 32.5% obscure by the moon with a maximum at 11:55 am (Paris time).
- Lille : 25% occultation by the moon with a maximum at 12:06 pm (Paris time).
- Lyon : 15.7% occultation by the moon with a maximum at 11:59 am (Paris time).
- Bordeaux : 22 % concealment by the moon with a maximum at 11:51 am (Paris time).
- Biarritz : 21.6 % Occultation by the Moon with a maximum at 11:48 am (Paris time).
- Marseille : 11.7% obscure by the moon with a maximum at 11:57 am (Paris time).
- Toulouse : 17.4% OCCULTATION BY THE Moon with a maximum at 11:51 am (Paris time).
- Strasbourg : 16 % obscure by the moon with a maximum at 12:08 p.m. (Paris time).
- Nice : 9.9 % occultation by the moon with a maximum at 11:59 am (Paris time).
15:40 – An observation of the difficult solar eclipse in the extreme southwest of France
According to the weather chain, the inhabitants of the Pyrenees and the Massif Central regions, in cities like Tarbes, Foix, Saint-Etienne or Le Puy-en-Velay, will have difficulty observing the course of the solar eclipse which will occur this Saturday, March 29, 2025 between 11 a.m. and 1 p.m. Indeed, the sky is likely to be “very busy” with clouds and heavy rains. Those who will not have the chance to observe the phenomenon will be able to console themselves with a next eclipse of sun visible in France on August 12, 2026, therefore in the middle of summer, with less chance of meeting weather disturbances!
15:04 – Bad weather, low concealment rate of the solar eclipse. East of France disadvantaged
This Saturday, March 29, 2025, the inhabitants of eastern France will only see a small piece of moon hiding a piece of the sun. Indeed, the inhabitants of the city of Strasbourg, prefecture of Bas-Rhin and the Grand Est region, will be less spoiled to observe the solar eclipse, with an obscuration rate of only 16% at 12:08 am at its maximum. In order not to fix anything, the weather channel announces this Saturday, unfavorable weather conditions in the east of France, “with cloudy coverage which should remain important in cities like Strasbourg, Besançon and Lyon”.
13:45 – The south -east of France benefited to observe the solar eclipse
Good news for the inhabitants of Perpignan, Avignon or Marseille. Saturday, March 29 at the end of the morning, at the time of the partial solar eclipse, the weather chain announces a “clear sky” or “little cloudy” in the south-east of France, favored by the Mistral and the Tramontane. In this region of France, the sun will be hidden by the moon at 14.2% in Perpignan (at the maximum of the eclipse at 11:52 am), 11.7% in Marseille (at the maximum of the eclipse at 11:57 am) and 13.3% in Avignon (maximum of the eclipse at 11:56).
13:17 – Partial solar eclipse: ideal observation conditions in the northwest of France
The Sun Eclipse of March 29, 2025 will be visible in France partially, masking 32.5 % of the surface of the sun in Brest while in Nice, the sun’s concealment rate by the moon will only be 9.9 %. This show will not be missed under any pretext for the inhabitants of the cities of Nantes, Rennes, Rouen, Paris and Lille because the weather chain announces “a clear sky” in “the northwest half of the country”, the region which is therefore the most advantaged for its observation, with “beautiful sunny periods”.
