April ENSO shift lifts northern coastal irradiance while suppressing Brazil and northern Argentina

South America’s April solar map shows why climate variability matters for energy planning

Solcast reported above-average irradiance along Colombia’s Pacific and Caribbean coasts and parts of southern Argentina.
Eastern and northern temperate regions, including areas from Buenos Aires toward Bolivia, saw reduced irradiance.
The pattern was linked to cloud and precipitation anomalies associated with an ENSO-neutral to El Niño transition.
