In 1977, the 3.4 Region SST for May/June/July was +0.4 or within the zone of ENSO Neutral conditions. Later that Summer, El Nino conditions started in the 3.4 Region in the August/September timeframe and lasted through February of 1978. Storm totals in the Atlantic were 6/5/1 and in the Pacific they were 8/4/0. The EASTPAC storm season ended on October 8th (about two months earlier than normal) primarily because the SSTs had increased to a +0.8 anomaly, i.e., a moderate El Nino had kicked in - so this was a rare case where a season with a low number of storms in the Atlantic basin did not equate to a significantly higher level of activity in the eastern Pacific.
