Conditions at Faja da Caldeira de Santo Cristo in May
May: Small, Clean and Full of Potential
May marks the real shift toward summer. Average swell heights are down to around 4ft (1.2m) with periods of 8.7s, pushing the surf into average, punchy, rideable territory. The S/SSW/SW window is still present at around 15% - actually one of the higher percentages of the year - but the energy in that window is concentrated in the 2-5ft (0.5-1.5m) range. These are fun-sized, grovelling waves rather than heavy winter freight trains. The rest of the wave rose is dominated by NNW, NW, W and WSW swells that wrap or filter in with less consistency.
Offshore winds become more routine: N/NNE/NE/NNW flow accounts for about 29% of wind observations, with ideal conditions 19% of the time. That means May often delivers clean, lined-up waves on a shortboard or groveller, even if a 6ft-plus day is rare. Air temperatures warm to 16.9°C (min 12.5°C, max 21.2°C), water temperature reaches 17.1°C, and rainfall drops to 1.98mm/day. If you want the best balance of clean conditions and manageable size, May is a strong bet.
