Conditions at Marinaretti in January
January: Midwinter Mix - Bora Grooms and Southern Pulse
January sits right in the heart of Marinaretti's surf season. The average swell height reaches about 3ft (0.9m) with an average period of 5.7s, putting the surf right at the boundary between short-period chop and punchy, rideable windswell. Swell from the preferred S/SSW/SW quadrant accounts for around 19% of the wave rose, and about 6.5% of the time the combination of direction and size actually delivers surfable waves over 3ft (1m). That may not sound like much, but on a south-facing Italian beach it is a solid winter baseline.
The wind story is also good: N/NNE/NE/NNW directions make up about 35% of all wind observations, with the 'ideal wind' score reaching 29%, one of the best months of the year. Air temperature sits near 10.7°C, water temperature is a cold 14.4°C, and the 2.42mm/day of rain means plenty of frontal activity. When a low pressure center tracks across the Mediterranean, expect Sirocco to push S/SW swell into the coast; when the pressure gradient tightens from the north, offshore Bora lines clean it up. It is small, but it is the season.
