If you want to attend a show offered by Dame Nature at Fontaine de Vaucluse, come and see the source overflow the first months of the year.
It should be noted that the level of the source varies constantly from year to year. Indeed, every year is different! The source may well spill for several months, or only dump a few days.
It should also be taken into account that the source pours after snow melt or after very heavy rains.
On average, the best time to come and see the source in flood is in March. According to one study, the monthly flow rate for March is 23.50 m³/s (data calculated over 56 years).
According to this graph, the most conducive months for the source to spill are: January, February, March, April and May.
If you visit the village of Fontaine-de-Vaucluse when the source level is low, usually from June to October, the ride is just as beautiful!
It would have to come every season to see the source in all its facets.
