About this spot

About

Graters is a low-profile, exposed reef break on Oahu’s North Shore near the Marconi area. It’s described as working only once in a while, with conditions and swell angles strongly influencing whether it offers rideable waves. The bottom is reef/coral with rocky hazards, and the spot is especially unforgiving at low tide because the reef can be very shallow for paddling back out. Sources specifically call out rocks/sharp shallow reef and sea urchins, so caution around the shoreline is essential. Currents can also become a factor during larger winter swells. For surfing, the wave is generally described as inconsistent: it can be lefts and rights when the swell is correctly angled, but it can also close out on bigger sets. Wind sensitivity is noted as a key variable for wave quality—cleaner surf tends to require favorable winds rather than just stronger wind alone. Winter conditions are the headline: January is highlighted as the best month, and the wider seasonal pattern points to winter (roughly November through March) for surf-focused trips. While rescue is not specifically reported for the spot itself, nearby medical facilities are in Kahuku, so plan accordingly if you are venturing out.
