Climate Data Historical

Located in the windward part of the Caribbean’s archipelago, Barbados enjoys a tropical, oceanic climate with hot and humid conditions that persist year-round.  The country enjoys an average temperature of 26.8°C, with no drastic changes in either seasonal or daily temperatures. Weather seasons can be classified as either wet or dry, with the wet season coinciding with the Atlantic hurricane season, which runs from June to November. Monthly average rainfall ranges from a peak of approximately 168.4mm (6.63in) during the wet season, to a low of approximately 39 mm (1.53 in), during the dry season. Barbados’s climate is heavily influenced by the El Niño Southern Oscillation (ENSO). The El Niño phenomena brings hotter and drier conditions during the months of June to August while La Niña brings colder and wetter conditions to the region. These phenomena have been historically the main determinants of the severity of weather events in the country. 

Temperature

  • Mean annual temperatures have increased from 0.6°C at an average rate of 0.14°C per decade since 1960.
  • There is insufficient daily observational data to identify trends in daily temperature extremes.

Precipitation

  • Mean rainfall over Barbados has increased during the months of September to November and by 12.9 mm per month (6.2%) per decade since 1960, but this increase is not statistically significant. This increase is offset partially by decreases of around 4.0 mm per month (2.1%) per decade during the months of June to August.
  • There are insufficient daily rainfall records available to identify trends in daily rainfall extremes.
