On average, the relationship between La Niña and below normal precipitation in New Mexico increases across much of New Mexico from winter to spring, and that is certainly true at Aztec Ruins and Chaco Canyon. However, since these stations are located in the northern section of the state, the precipitation deficits are not as large as those noted across the southern tier of the state. During the six strong La Niña events, precipitation is below normal during five of the events at both sites.

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

Precipitation values for 3-month periods during the 19 La Niña starting in 1950. Events 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 La Niña Event was considered to be strong are colored in purple. "M" represents a 3-month period with missing data. Finally, the percents of longterm normal for all La Niña events and for the strong La Niña events are listed below each graph.
