Hash Point seasonal overview
Best Surf Season (October - March)
The North Atlantic roars to life during these months, with powerful extratropical cyclones marching eastward across the ocean. This climatological uptick in storm activity feeds Hash Point with consistent, long-period groundswell from the NW and NNW – the dominant swell windows here. Average wave heights hover between 1.8m and 2.2m, with periods often exceeding 12 seconds, translating to solid, rippable surf. Crucially, the percentage of offshore wind (N through E) peaks from December through February, topping out at 62% in December. When the wind locks in from the E or NE and a strong W-NW swell arrives, the point comes alive with clean, lined-up waves. This is the prime window for scoring Hash Point at its best.
Fair Surf Season (April & September)
These transitional months mark the shift between winter fury and summer doldrums. In April, the average swell height drops slightly to 2.0m, and the period shortens to ~11s, but there are still occasional pulses of NW groundswell. Offshore wind frequency falls to around 39%, meaning more days with variable or onshore flow. September sees a similar pattern – average height 1.5m, period 10s, with wind ideal 46% of the time. While not as consistent or powerful as winter, these months can still deliver fun sessions when a late-season storm or an early autumn front aligns with an easterly breeze.
Low Surf Season (May - August)
Summer settles in over the North Atlantic, and the storm track shifts northward, leading to a significant drop in swell energy at Hash Point. Average wave heights fall to 1.6m and periods shrink to the 7-9 second range – often powerless and short-period. The swell direction becomes heavily dominated by the NNW (over 93% in July and August), which is far from ideal for this WSW-facing spot. Furthermore, the frequency of offshore wind dips to its lowest levels (35-48%), with increasing northwesterly and westerly components that blow directly onshore. During these months, the surf is typically small, weak, and bumpy – best for a longboard or a groveler, but far from the quality that winter brings.

Conditions at Hash Point in May
May: Summer Slump Begins
May sees a noticeable shift toward summer patterns. Average swell height falls to 1.8m and period drops to 9.4s – now we're in the 'average, rideable' range. The swell direction becomes heavily dominated by NNW (62.9%), with NW at 19.3%. This extreme northwesterly direction is far from optimal for Hash Point's WSW orientation; the waves will be shadowed and less consistent. Offshore wind frequency is at a low 36%, and the wind patterns show increasing NW and NNW components (24.4% and 28.8% respectively), which blow cross-shore or onshore. The result is typically small, weak surf with bumpy conditions. Mornings can still offer clean windows when the land heats up and a light easterly breeze develops, but don't expect big, powerful waves. This month is best suited for longboarders or surfers willing to grovel on a high-volume board.
