conditions thereafter - this is the dry season, so observed rainfall totals were small. 3-Month Outlook September to November - Rainfall Outlook: Over the next three months, the West African Monsoon will move south. Many areas of west and central Africa are likely to be wetter than normal. Eastern
this is more difficult, increasing health risk to humans. Analysis of the new data has shown that global annual / seasonal mean of maximum daily wet bulb temperature, a measure of humidity, has increased by around 0.2°C each decade between 1973-2022. This rate of change is even higher when looking
balanced (Climatological Odds). This wet signal extends into northern Mozambique. Otherwise, much of southern Africa is more likely to be drier than normal, although in absolute terms the potential rainfall deficit is likely to be small as this is towards the end of the dry season.
