July: Winter's Peak Battles the Coastal Wind
July stands at the heart of the austral winter, with average swell still maxed out at 1.9m (6.2ft) and the surf direction shifting further south. S-sourced swell rises to 18%, while SSW still supplies 70%, giving Santa Rosa a more southerly, angled pulse than the summer months. The average period dips to 12.8s, indicating a touch more local wind influence mixed into the long-period groundswell. Wind-wise, there is no letup: S and SSW make up roughly 94% of the directional distribution and ideal offshore wind remains at 0%. Water temperatures drop to 15.9C, with air temps around 16.9C. It's cold, combative and powerful - a month for winter wetsuits and a healthy respect for the ocean.
