NOAA's weekly Niño 3.4 sea surface temperature anomaly is +3.3 °C for the week centred November 4, 2026, in the very strong range of the usual thresholds, about level with four weeks earlier. The latest Oceanic Niño Index is +2.46 °C for Aug–Oct 2026; the relative index (RONI) is +2.00 °C. NOAA's Climate Prediction Center status is \"El Niño Advisory\": \"El Niño conditions are present and strengthening\" (discussion of October 8, 2026). CPC puts the chance of a strong to very strong El Niño through January–March 2027 at over 83%, and of the strongest El Niño since 1950 in October–December 2026 at 83%.","indices":[{"key":"nino34","name":"Niño 3.4, weekly SST anomaly","value":3.3,"display":"+3.3 °C","unit":"°C","period":"week centred November 4, 2026","cadence":"weekly","publisher":"NOAA Climate
