| The season 2008/2009 The current season had a slow start with no rain from July to September, and each month from October to December below average for the month. However January to March were exceptionally wet. This pattern is to be expected while the Southern Oscilation is in the la Nina phase - cooler and wetter weather from December to February. Rainfall records for Johannesburg, South Africa, as recorded by Irwin Juckes from 1983 to 2009.

Johannesburg is in a summer rainfall region, that has experienced cycles of drier and wetter weather of about 9 years each over the last century. Compare these cycles with my rainfall records from 1983 to 2007. |

Early rainfall history (reference)
Recent rainfall historyThese published statistics are for the period from the start of the 20th century to the early 1980's. The rainfall records in this website, recorded in Edenvale, Ekurhuleni, on the east of Johannesburg, begin in 1982. The expectation was that the 1990's would be wetter and the decade of 2000 drier. However the pattern seems to have become less consistent. Could this be due to global warming? |
