10 Seasonal Outlook (Statistical Model) Victoria Jul-Sep The expected MEI, adjusted by the Indian Ocean Dipole Mode Index and also by recent values of the SOI, for MAY/JUN is Such a value of MEI indicates a sea surface temperature distribution that corresponds to a very weak La Niña. This suggests: RAINFALL: There is a very slightly enhanced chance that total JUL/AUG/SEP rainfall will be above normal in most districts OVERNIGHT TEMPERATURES:There is a very slightly enhanced chance that average JUL/AUG/SEP overnight temperatures will be above normal in some districts DAYTIME TEMPERATURES: There is a very slightly enhanced chance that average JUL/AUG/SEP daytime temperatures will be below normal in some districts

11 Monthly Outlook (Statistical Model) Melbourne In Melbourne, at this time of the year, a combination of the MEI, the DMI, and the MJO Phase, such as what we have operating now, suggests, over the following 30 days: RAINFALL: There is a 41% chance of it being wet, a 33% chance of normal rainfall, and a 26% chance of it being dry. OVERNIGHT TEMPERATURES: There is a 36% chance of warm nights, a 33% chance of normal overnight temperatures, and a 31% chance of cool nights. DAYTIME TEMPERATURES: There is a 25% chance of warm days, a 32% chance of normal daytime temperatures, and a 43% chance of cool days. 11
