By spring, the effect of El Niño in the southwestern mountains increases, and the average increase of precipitation increased as well, particularly at Luna Ranger Station. In strong El Niño events, increases in precipitation ranged from 132% to 158% of the long term normal. In 1992 was an especially wet spring, particularly in May, and Luna received March-April-May precipitation that is almost four times the long term average.

A description of the graphs is located at the bottom of the page.

Precipitation values for 3-month periods during 18 El Niño Events since 1949-50 are plotted with respect to the long term precipitation average, listed to the right of the graph. The precipitation totals for each 3-month period are plotted above or below each bar. Years for which the El Niño Event was considered to be strong are colored in drk green. "M" represents a 3-month period with missing data. Finally, the percents of long term normal for all El Niño events and for the strong El Niño events are listed below each graph.
