Snow in the Caribbean? Examining Frost Records on Jamaica's Highest Mountain Peaks
By Chloe Bennett
Jamaica sits firmly within the tropical maritime belt between latitudes 17°42' N and 18°31' N. Warm North Equatorial currents circulate past its shores. Northeast trade winds sweep across the island year-round, regulating coastal humidity and maintaining winter temperatures in Jamaica that rarely drop below 70°F (21°C) at sea level. The Caribbean climate produces a predictable annual thermal band along the perimeter, where frost is physically impossible.
Interior geography tells a dramatically different story. The island features an exceptionally rugged topography dominated by east-west cordilleras. Moving just 15 miles inland from the parish capitals, elevation gains create microclimates ranging from tropical rainforests to a temperate subtropical highland climate. These stark altitudinal gradients alter air density, ambient moisture, and nightly temperature minimums.
During the northern hemisphere winter, spanning December through March, continental polar air masses occasionally push southward across the Gulf of Mexico. Locally known as "Northers," these cold fronts weaken before reaching the Greater Antilles. Even in their attenuated state, they force marine air upward against the island's steep slopes. The resulting uplift chills incoming air masses and sets the stage for the island's lowest verifiable readings.
