Cave - surf spot statistics

Cave in Portugal offers consistent surf conditions year-round, with the best months falling between October and March. During this period, the swell is predominantly groundswell-driven (63-91% probability), providing powerful, clean waves with an average size ranging from 1.7m to 2.2m. November to February stands out as the peak season, featuring the largest swells (2.0-2.2m) and the highest groundswell consistency (74-91%), making it ideal for experienced surfers seeking quality waves. However, wind conditions can be challenging, with only 34-38% of days offering favorable offshore winds—January and December slightly edge out other months with marginally better wind probabilities (38% and 36% good wind days, respectively). From April to September, conditions weaken significantly, with wind swells dominating (35-83%) and smaller wave heights (1.1-1.7m). Summer months (June-August) are the least reliable, with minimal groundswell (15-26%) and poor wind conditions (only 27-33% good wind days). While still surfable, these months are better suited for beginners or those prioritizing warmer water over wave quality. September and October mark the transition back to better surf, with increasing groundswell influence (46-63%) and improving winds (36-37%). For the best balance of swell energy and manageable winds, mid-fall (October) and early spring (March) can be good alternatives to the crowded winter peak. Overall, dedicated surfers should target winter for powerful waves, accepting the higher likelihood of onshore winds.
