Conditions at Ferrugem in July
July: Mid-Winter Force
July keeps the cold-front engine running. Ideal surf wind remains high at 70%, average swell height is 4.3ft (1.3m), and period is a solid 9.3s. Swell direction edges back toward the E quadrant: ENE 17.3%, E 17.8%, ESE 15.3% and SE 12.8%, with SSE (14.7%) and S (15.9%) still in the mix. This balance of true E/SE groundswell and occasional S-swell, combined with long periods, means Ferrugem can produce clean wrapping lines on the better sandbars.
Wind patterns are similar to June: NNW 17.7%, SSW 11.2%, SW 9.5%, with the offshore WNW/NW/W block contributing near 20% of readings. Water temp bottoms out at 17.6°C and air temperature at 15.1°C, making July the coldest month, but the ocean is very much alive. The average height may sound modest, but 3-5ft (1-1.5m) long-period surf with light offshore winds will have the beachie firing. This is a favorite month for the local crew.
