Climate Forecast Aruba
PERIOD APRIL, MAY, JUNE (AMJ) AND JULY, AUGUST, SEPTEMBER (JAS).

What influences the next season?
Recent observations:
Weak La Niņa conditions have emerged in December
2024, with Sea Surface Temperatures (SSTs) having anomalously
cooled to 0.7°C below average by January 2025, but rebounded to
near-average in February.
Model forecast and guidance:
The forecast models forecast a return to
ENSO neutral conditions in AMJ (~80-85% confidence), more likely than
not remaining neutral through JAS (~55-65% confidence).
Expected impacts on rainfall and temperatures:
La Niņa conditions are
often associated with increased heavy shower activity in the southeastern
Caribbean, but the opposite in the northwestern Caribbean through April.
ENSO neutral conditions do not contribute to seasonal forecast skill.
