From around the 20th of June, a long-wave trough is expected to peak over SA, bringing good potential for cold fronts and the like to pass through, in turn increasing potential for rainfall.

So far, the outlook isn't particularly favourable for heavy rain, with the three day total from Saturday to Monday predicted to fall between 20 to 30 millimetres. However, there is still time for rainfall predictions to increase, especially as these systems are subject to change.

Further ahead than this the outlook is less certain. An increase in surface temperatures for eastern equatorial Pacific waters means that an El Nino could arise by the end of winter. However northern Indian Ocean waters are also warmer, which generally means more moisture can be drawn in by rainfall systems.

The good news so far is that the rainfall that has already fallen over the last month should help to produce a better crop yield than previously expected.
