A strengthening super El Niño, with Niño 3.4 anomalies already exceeding +2.8°C in September 2026 and models projecting peaks near +3.5–4.0°C later in the year, is the dominant near-term driver pushing October global temperatures toward record territory. Combined with the long-term anthropogenic warming trend and exceptionally warm baseline ocean conditions, this supports widespread above-normal land and ocean temperatures during the August–October period, per WMO and NOAA multi-model ensembles. However, the lagged global temperature response to El Niño, potential model spread in exact monthly anomalies, and competition with prior record Octobers from 2023–2025 create substantial uncertainty, leaving trader consensus evenly split on whether the month finishes first, second, or third warmest versus lower.
