#57 Just South Of Toulon. Heading For Cap D’agde, We’d Refuelled In Porquerolles And Were Off The Coast When This Started To Role In

A wide ocean view showing a low horizontal band of clouds, typical of the bottom of the ocean
The Mistral had been blowing in the Gulf of Toulon for several days (F10) and we holed up in Elba until it had calmed down. Apparently, in this part of the world, when the cold, wet, Mistral stops blowing from the North, it’s met by warm, dry equatorial air coming up from the South. When they meet, this is what forms. My first time ever sailing in that part of the world, this was entirely new to me, so to say it came as a surprise is a little understatement.The night passed in dense fog (we had no radar on-board), and was spent with 2 on watch, 15-minute radio calls giving away our position, dodging shipping coming out of Marseilles and rounding that corner of France, and watching the clock tick down to daylight. We tied up in Cap D’agde the following morning - yacht delivery complete.
