Newport Beach generally benefits from consistent ground swells throughout the year, with the highest probabilities occurring from April to September, peaking at 87% during June, July, and August. During these months, wind swells are minimal (8–10%), and the chance of no swell is low (4–5%), making summer and early fall the most reliable periods for surfable waves. However, wind conditions are less favorable in these months, with bad onshore winds dominating (77–85% probability), particularly from May to August. The mean swell size remains small to moderate (0.7–0.9m), which suits intermediate surfers but may lack power for advanced riders. Winter months (November–February) bring slightly better wind conditions (31–36% good winds), though ground swell consistency drops (56–70%) and no-swell days increase (16–30%). December has the highest likelihood of no swell (30%) and the smallest average wave height (0.7m). Late fall and early spring (October–March) offer a compromise, with decent ground swell frequency and marginally better wind odds. For the best balance of swell consistency and acceptable wind conditions, late winter (February–March) and early fall (September–October) may be preferable, though surfers should expect smaller waves and occasional unfavorable winds. Overall, summer provides the most consistent waves but with challenging wind patterns, while winter sees improved winds at the expense of reduced swell reliability.
