Boston Bay is on the northeast coast of Jamaica in Portland Parish, where the Blue Mountains come close to the sea and the Atlantic swell from the northeast wraps around the headlands to produce one of the stronger shore breaks on the island. The bay is rocky on both sides, with a central strip of coarse sand that holds the beach between two low headlands. The Atlantic arrival here is not the gentle Caribbean of Negril or Montego Bay — Boston Bay faces northeast and receives the full trade-wind swell at 0.5 to 1.5 metres on most days, building to 2.0 metres or more during winter north swells from November through February. That swell regime has made Boston Bay the primary bodysurfing and bodyboarding beach in eastern Jamaica; on a good north swell day the inside shore break runs consistently enough for experienced water riders. The beach access is immediately off the main A4 road, which is the nearest the road comes to the sea along this stretch of coast, and the roadside vendors above the beach represent one of the strongest claims in Jamaica for the origin of jerk cooking. The Boston Bay jerk pits — a cluster of barrel smokers and open wood-fire grills — have been operating here since at least the 1940s and are documented as the geographical source of the style: pork and chicken slow-cooked over pimento wood with the dry rub that defines Jamaican jerk. The roadside stalls serve directly; there are no restaurants. The approach from Port Antonio, 10 km to the west, takes about 15 minutes on the coastal road; the drive itself passes through coconut grove and the occasional banana plantation backed by the forested lower slopes of the Blue Mountains. The tidal regime at Boston Bay is Caribbean-influenced mixed semidiurnal, spring range roughly 0.4 to 0.6 metres. The tide affects the shore break height and the beach width — on a spring low the beach widens by 15 to 20 metres and the shore break runs at a lower, more manageable height for waders. The flooding tide raises the break height and steepens the face for bodyboarders. Shore anglers fishing from the northern rocky point on the early morning ebb target the kingfish and jack that hold in the current seam where the Atlantic enters the bay.
