Osbourne - surf spot statistics

Osborne, Canada, is a surf spot that primarily relies on wind swells, with ground swells making up a smaller portion of the swell mix. The best months for surfers are typically September through December, when the swell size is larger (averaging 1.4m to 1.7m) and ground swells contribute more, especially in September (22%) and December (20%). Wind conditions are challenging year-round, but the least unfavorable winds occur in July and August, with 34% and 35% good wind days, respectively. However, those summer months also bring the smallest swell sizes (1.1m to 1.2m). For surfers prioritizing wave quality, late fall and early winter (September to December) offer the best balance of swell size and ground swell presence, despite the high percentage of bad wind days (73% to 84%). The worst time to surf Osborne is from May to August, when wind swells dominate (85% to 94%) and waves are generally smaller and less powerful. Overall, the spot suits experienced surfers who can handle challenging wind conditions and prefer a mix of ground and wind swells.

December at this surf spot offers decent but inconsistent conditions for experienced surfers. The average swell height is 1.7m with a period of 8.6s, providing reasonably powerful waves when conditions align. The swell direction is most favorable from the SSW, SW, and S, with a significant portion of waves in the 1.5-2.5m range—ideal for good surf when combined with clean wind. However, the wind is only ideal for surfing 16% of the time, meaning many days may be blown out or choppy. The dominant winds come from the W, WNW, and NW, often in the 20-40kph range, creating onshore or cross-shore conditions that can disrupt wave quality. Swells from the ENE and E contribute some clean, smaller waves, but they’re less frequent. December sees a mix of rideable days (especially when SW winds align with SSW swells) and challenging conditions, so patience and timing are key. It’s best suited for surfers comfortable with variable wind and swell patterns.
