Good Rats - surf spot statistics

Good Rats offers consistent surf conditions year-round, but the best months for quality waves are typically December through February. During this period, ground swell dominates (79%–83%), providing powerful, well-organized waves with an average swell size of 2.2–2.4 meters. Wind conditions, however, are less favorable, with bad winds (onshore or cross-shore) occurring 74%–78% of the time. The upside is that the strong winter swells produce longer, cleaner rides when the wind does cooperate. March and November are solid transitional months, with decent ground swell (67%–69%) and slightly improved wind chances (28% in March, 23% in November). The rest of the year sees progressively weaker swells, with wind swells taking over from May to September—resulting in smaller, choppier waves. The worst conditions are in summer (June–August), when ground swells drop below 40%, swell size averages just 1.1–1.2 meters, and bad winds peak around 77%–80%. If you prioritize wave power and consistency, winter is the optimal window despite the wind challenges. For smaller but potentially cleaner conditions, late spring (April–May) and early fall (September–October) offer a balance of moderate swells and slightly better wind odds.

In May, Good Rats offers surfers decent conditions with an average swell height of 1.3m and a solid period of 10.9s, providing well-organized, rideable waves. The swell direction is primarily from the SSW, WSW, and SW, with the majority of waves ranging between 0.5m and 2.5m—ideal for intermediate to advanced surfers. WSW swells dominate the larger wave categories (1-2.5m), making it the most productive direction. Wind conditions are favorable for surfing only 29% of the time, with lighter winds (0-20kph) from the WNW, NW, and N occasionally offering clean sessions. However, stronger winds from the SE, SSE, and E can create choppy or less ideal conditions. Overall, May delivers consistent, mid-sized waves, but wind reliability is hit or miss, requiring patience for optimal sessions.
