Seasonal climate variability affects the amount of chilling during dormancy, the accumulation of heat units during fruit development, threat from freeze and ice damage, and impacts from diseases and pests.
In the Southeast, El Niño years tend to have more chilling and rain during the dormant season than normal, while La Niña years have less chilling and may require additional irrigation during fruit growth and maturation. With dry conditions and low humidity, La Niña years may also impact pest and disease incidence.
During Neutral years damaging freezes are more common. (See the Freeze forecast)
