Portland Parish

Portland Parish occupies the northeastern corner of Jamaica, where the Blue Mountains — the island's highest range, reaching 2,256 metres at Blue Mountain Peak — descend steeply to the Atlantic coast. The combination of the mountain mass, the northeast trade winds, and the orographic rainfall makes Portland the wettest parish in Jamaica and one of the lushest landscapes in the Caribbean, in sharp contrast to the drier south coast parishes. Port Antonio, the parish capital, sits on two bays divided by a narrow peninsula — the Titchfield Peninsula — and was Jamaica's original resort destination in the early twentieth century, before Montego Bay took that role. The northeast coast from Port Antonio to the Río Grande mouth and east to Boston Bay and Long Bay faces the Atlantic with varying degrees of exposure. Boston Bay is the most wave-active beach on this stretch and has a claim to being the origin point of Jamaican jerk cooking — the roadside jerk pits above the beach predate the tourist versions in Ocho Rios and Montego Bay by decades. The tidal regime is Caribbean-influenced mixed semidiurnal, spring range roughly 0.4 to 0.6 metres. The Atlantic swell from the northeast is the dominant coastal variable, not the tide; during winter north swells the Boston Bay shore becomes a significant bodysurfing and bodyboarding beach. Tide data comes from Open-Meteo Marine gridded model — accuracy within plus or minus 45 minutes on timing and 0.2 to 0.3 metres on height.
