Conditions at Il Bunker in May
May: Late Spring Funk - Small Windswell and Stubborn Breezes
May is the point where Il Bunker shifts into a low-energy spring pattern. Average swell drops to 2ft (0.6m), period shortens to 4.5s, and ideal wind conditions are present only 12% of the time. The southern quadrant still delivers waves - S is 16.9%, SW 14.1%, SSW 10.0% - but most of that is sub-1m, groveling material. WSW and SSE fill out the spectrum. On the wind side, offshore N/NNE/NE/NNW totals only around 29%, while SSE/S/SSW/SW onshore flow totals another 29%, so conditions are often compromised by the developing thermal sea-breeze cycle. Air temperatures jump to 17.8°C, water to 18.9°C, and rainfall is lower at 1.67mm/day. Dawn patrol is your best bet for clean, small waves before the summer breeze takes over.
