Consensus Outlook for the Southwest Monsoon (JJA 2015) Rainfall and Temperature over Southeast Asia

For the upcoming Northern Hemisphere summer (Jun-Jul-Aug) season in 2015, there is strongly enhanced probability for below normal rainfall over the southern part of the Maritime Continent and the eastern margins of mainland Southeast Asia. Over the remainder of mainland Southeast Asia there are slightly enhanced probabilities for normal to below normal rainfall, while over the Philippines there are slightly enhanced probabilities for normal to above normal rainfall.

Above normal temperatures are most likely over much of the Southeast Asia region for the Northern Hemisphere summer, with the highest probabilities over the western Maritime Continent and mainland Southeast Asia. Below normal temperatures are slightly favoured over a relatively small area in the south-eastern part of the Maritime Continent.
