In an updated travel advisory, the FCDO said coordinated strike action and large-scale demonstrations in the country are next planned for Thursday 6 April, and may start the evening before and run for several days.
Earlier this month Brits travelling to France were warned protests "could turn violent" after pension reforms passed without a vote saw the French retirement age rise from 62 to 64.
"Since mid-March there have been spontaneous protests in central Paris and elsewhere in France," the FCDO said.
