These maps are a scorecard of warm Northern Hemisphere summers versus cool ones (top) and wet versus dry ones (bottom) for all 29 El Niño summers on record, from 1950–present. For this analysis, an “El Niño summer” is any summer (June-August) leading into a winter (December-February) with El Niño conditions, regardless of whether El Niño was officially in place in the summer. Red areas mean warmer-than-average summers outnumbered cooler-than-average summers during El Niño, and blues mean cold El NIño summers outnumbered hot ones. Brown areas mean El Niño summers were dry more often than were wet; green areas mean wet El Niño summers outnumbered dry ones. In both maps, the darker the color, the more lopsided the count. In other words, the darker colors indicate how reliable or frequent the specific climate anomaly was at a given place, not how intense it was.
