During the period from August through 15 October, anomalously warm conditions persisted in most of mid and high latitude regions of the Asian and American sectors of the northern hemisphere; exceptions are Mexico through September, central USA up to September, and eastern USA in October. Africa in general experienced warmer than normal conditions, while Europe was in general anomalously warm except in August. In Australia, anomalous temperature signals changed from cold in August to warm since September. The equatorial Americas also experienced anomalously warm temperatures. Moderately drier than normal conditions were seen in many parts of East Asia including Mongolia, the Middle East where severe dry conditions have been persisting, along with other parts of west Asia, and adjoining Africa; in Africa, southern parts also experienced dry conditions. Several parts of north and central North America experienced warm and/or dry signals. Dry conditions have also prevailed in southern Australia since late August. On the other hand, anomalously wet conditions were seen in northern tropical Africa and the western tropical Pacific. Near normal surface temperature conditions were seen in the tropical Pacific.
