St Ives in the United Kingdom offers surfable conditions year-round, but the best months for quality waves and favorable winds are typically from late autumn through early spring, particularly November to February. During these months, ground swell dominates (65-82%), providing more consistent and powerful waves with mean swell sizes ranging from 2.0m to 2.4m. However, wind conditions are often challenging, with bad onshore winds prevailing 88-91% of the time, which can make sessions messy. The prime window is likely December to February when ground swell percentages peak, but surfers must be prepared for strong winds. Spring (April-June) and summer (July-August) see a significant drop in ground swell activity, replaced by wind swell (42-77%) and smaller waves (1.1-1.4m). While wind conditions improve slightly (15-17% good winds), the lack of consistent ground swell makes sessions weaker and less reliable. September and October mark a transitional period, with ground swell increasing again (37-53%) and better wave energy returning (1.3-1.7m). For surfers seeking cleaner conditions, these shoulder months might offer occasional good days, though wind remains a limiting factor. Overall, winter delivers the most powerful waves, but patience is required to score optimal wind alignment.
