The Olive tree thrives in areas with Mediterranean climate, where mild winters are followed by sunny springs and hot summers. The areas where olive trees are cultivated for commercial use must have an average annual temperature of 60-68 °F (15-20 °C). The absolute maximum temperature can reach 104 °F (40 °C) without causing damage, but the minimum should not fall below 20 °F (-7 °C). Lower temperatures than this can cause serious damage to the trees. Of course, the temperature of 20 °F is only indicative, because the resistance of the tree in cold depends on other factors as well, such as how quickly the temperature drops, the length of the frost, the presence of strong cold winds, humidity, germination and health of the tree variety, weather conditions before frost etc. In general, we can say that the olive tree cannot not be cultivated commercially in areas where the temperature often drops below 20 °F (-7 °C). However, a certain amount of cold is necessary for the fruit set. This is the reason why olive trees cannot be grown in tropical climates.
