Eastern Equatorial Pacific is Now Record Warm!

Last week, the Nino12 SSTA warmed to +4.6C and Nino3 SSTA surged to +3.5C combining for the warmest equatorial eastern Pacific Ocean surface temperature anomalies on record. In the Nino34 SSTA region, where ENSO phase is assessed, conventional Nino34 SSTA is +2.7C qualifying as Super El Nino while the new relative Nino34 SSTA index is +1.8C just below the Super El Nino threshold.

East/Southeast Brazil Forecasts Trend Wetter

ECMWF is most aggressive with the ongoing rains in Southeast/East Brazil. The outlook is supported by ongoing negative Antarctic oscillation (-AAO) which implies semi-permanent low-pressure troughs in the middle latitudes. ECMWF projects a semi-permanent low-pressure trough east of Argentina located across an area of relative cool SSTA. Meanwhile, east of Brazil, a marine heat wave (MHW) is expected to strengthen. The upper trough entrains increased low-level atmosphere moisture across the MHW driving a wetter Southeast/East Brazil climate likely to last through spring.

  • Latest Multivariate ENSO Index Report

    09/13/2026, 12:11 pm EDT
    The JUL/AUG 2026 multivariate ENSO index (MEI) was +2.5. MEI is an excellent indicator of the atmospheric response to the equatorial Pacific Ocean sea surface temperature anomaly (SSTA) regime. When comparing the JUL/AUG 2026 MEI with the past 3 previously most intense El Nino episodes on record, the 2026 signature ranks strongest. Note that after rapid intensification of previous strong El Nino events, there is a tendency of MEI to level off except for the 1982-83 event which peaked in strength well into the second year of the event.

    • Glance at U.S. Population Weight HDD Forecasts for NOV-26 to MAR-27

      09/15/2026, 9:19 am EDT
      The initial U.S. gas population weight HDD forecast for the 2026-27 cold season reveals a mild regime with each month forecast below the 10-year/30-year climatology. Regionally, all zones are warmer than normal for NOV-26 to MAR-27 except near the 10-year normal for Texas.
