What has been a dismal year so for with respect to rain last night we had 24 mm and the good news it doesn’t look like its finished.
According to the Sat map below; there is a mass of cloud to our west (reddy/brown colour) and it seems to be moving in our direction. What we have found in the past is that our big rains come in from Angola, which this system is doing.
Temperatures are beginning to drop and it feels like winter is on its way. See our updated weather page
