Conditions at Itapiruba in May
May: The South Atlantic Fires Up
May is the beginning of the prime window. Average period jumps to 9.9s, the highest of the year so far, and average height sits at 5-6ft (1.7m). The swell rose pivots dramatically toward the south: S alone accounts for 19.3%, SSE for 17.1%, and SSW for 4.2%, while E-ESE-SE still contribute a solid background of trade-wind swell. More importantly, these southern swells arrive with longer intervals and more punch. A large percentage of waves land in the 5-8ft (1.5-2.5m) range, especially from S and SSE, making for hollow, powerful peaks on the sandbars.
The wind picture improves too. Ideal-window frequency hits 57%, with NNE (18.9%) decreasing and SSW (10.5%), SW (12.6%) and WSW (7.6%) becoming much more common. The days when a cold front clears the coast and the wind swings to the W-NW quadrant produce standout sessions - glassy, lined-up waves under clearing skies. Water temperature cools to 21.3°C and air to 19.9°C, so a 3/2 wetsuit is now the call. Rainfall is moderate at 3.45mm/day. This is a serious surf month.
