Conditions at Ilha dos Lobos in May
May: Winter Groundswell Machine
May is arguably the best month of the year at Ilha dos Lobos. The average period jumps to 9.8s -- the highest of the year -- while average heights reach 1.7m (5-6ft). The swell direction shifts south: S (18.1%), SSE (16.7%), ESE (13.7%), SE (13.4%) and E (11.5%) make for a rich mix, and there is plenty of size in the 1.5-2m (5-6.5ft) and 2-2.5m (6.5-8ft) range, especially from S and SSE. These are real groundswells generated by mid-latitude cyclones rolling through the South Atlantic.
Offshore wind opportunities are at their peak, with ideal conditions around 50% of the time. The W/NW/NNW flow is more frequent as cold fronts clear the coast, giving May a combination of power and clean surface that the summer months simply cannot match. Air temps drop to 16.6°C, water temp to 20.4°C, so booties may still be optional but a spring suit is becoming necessary.
