Good-bye El Niño, hello La Niña. Forecasters are seeing a shift in weather patterns over the Pacific Ocean that typically translates into an
especially dry period for Southern California. La Niña is a natural, periodic climate change in which a cooling trend over the Pacific leads to
below-average rainfall in this region.
Orange County could face an exceptionally dangerous fire season. Since July 1, the county has received 1.88 inch of rain – eight inches below normal.
And the National Weather Service says no major storms are in sight.
La Niña can cool local ocean waters during the summer, so swimmers and surfers might find water temperatures in the low 60s or high
50s, rather than the normal high 60s to low 70s. One cautionary note: These same forecasters said an emerging El Niño this winter would bring
above-average rain to Southern California.
