The headland's rock platforms and reef-fringed shoreline create sheltered inshore snorkeling terrain, with clear waters around the cliff base revealing gutters, boulder gardens, and shallow caves. The headland overlooks Grants Beach below — a sweeping stretch of sand where the surf breaks off the point. Snorkelers explore the reefy edges at the base of the headland, particularly on calm, low-tide days when the submerged rock platforms are most accessible and the water clarity is at its best.","intermediate",null,"published",{"name":59,"amplitude":75,"phase":91,"latitude":22,"model":107,"epoch":108},[60,61,62,63,64,65,66,67,68,69,70,71,72,73,74],"2N2","J1","K1","K2","M2","M4","MF","MM","N2","O1","P1","Q1","S1","S2","T2",[76,77,78,79,80,81,82,83,84,85,86,87,88,89,90],0.025137994711353785,0.008931210627032138,0.17794824099483897,0.03400198438322234,0.5266816506095047,0.005940048636000638,0.0013674093184250194,0.005086149000581637,0.10676534003896553,0.09816007262562867,0.056202613828469354,0.021715382419001998,0.013953242741409619,0.12972573575574406,0.00293231106723236,[92,93,94,95,96,97,98,99,100,101,102,103,104,105,106],278.2067492423429,359.839071899023,338.2229542053406,303.87259459085755,303.7938600542446,320.8901940771791,191.64866862660557,221.09676227385182,295.38367915805793,310.5585049513991,336.26846577956553,261.212299489075,354.0417825487804,317.28160529964543,335.77893802686833,"EOT20","1992-01-01T00:00:00Z",[110,115,119,122],{"name":111,"description":112,"severity":113,"season_start":36,"season_end":114},"Ocean swell and surge","The exposed headland receives open ocean swell.
