Climate Forecast

What influences the next season? El Niņo Southern Oscillation (ENSO) Recent observations: In recent weeks, sea-surface temperatures (SSTs) in the equatorial eastern Pacific (NINO3.4) have fluctuated around average, meaning neutral El Niņo conditions.

Model forecast and guidance: Most models, suggest temperatures to remain around average by SON and DJF, thus favouring neutral (65-70% and 55% confidence for SON and DJF, respectively).

Expected impacts on rainfall and temperatures: The ongoing ENSO neutral state will have little effect on rainfall or temperatures.

FORECAST VALID THROUGH FEB 2018: Rainfall expectations for Aruba: SON, 80% for normal to above normal; DJF, 85% for normal to above normal. Temperature expectations for Aruba: SON, 80% for normal to above normal; DJF, 80% for normal to above normal.

HURRICANE SEASON 2017: Hurricane season for the Atlantic region runs from June 1st through November 30th.
Experts expect for Atlantic hurricane activity in 2017 a slightly above normal season.
