Conditions at St. Laurent du Var in December
December: Maximum Winter Energy
December brings the longest average swell periods of the year (5.7s) and a solid average height around 2ft (0.6m). The S/SSW/SW/WSW window accounts for over half the total swell energy, with SW (20.0%) and SSW (14.5%) dominating. There is also a slight increase in the bigger categories: 7.2% of swell reaches 1-1.5m and 1.3% reaches 1.5-2m, so the chance of a proper 5ft (1.5m) wave is better than any other month.
Offshore winds remain frequent at 34%, especially light N/NNE flow. Air temperatures cool to 11.7°C and water temperatures drop to 15.5°C, so winter rubber is a must. Rainfall averages 2.39mm/day. If the Gulf of Genoa low aligns with a NE offshore wind, December can offer clean, punchy, surprisingly fun waves on this normally mellow Riviera beach break-though you'll still want to keep expectations in check for an average 2ft day.
