Belfast enjoys a temperate oceanic climate influenced by its coastal position on the Irish Sea. The maritime moderating effect limits temperature extremes, creating mild winters and cool summers. The urban heat island effect slightly mitigates nighttime temperatures in the city center.

Harbor Area: Direct maritime influence with more frequent winds
