Orange and red shading represent values above the 80th (Warm) and 90th (Hot) percentile, respectively; regions shaded in light and dark blue indicate values below the 20th (Cool) and 10th (Cold) percentile, with respect to the 1981-2010 climatology. The data used in this map

However, ENSO is most likely to remain neutral through the next three months. More information on typical impacts can be found here: https://www.metoffice.gov.uk/research
