"Like I said, Tuesday and Wednesday will be pretty rainy, but things are looking a little better for Thursday. This whole period is looking like it's going to be wet every day, though.
"It's a case of more or less wet. Again, Friday will bring more showers."
There would be a high of 26C on Monday and 25C on Wednesday, Bakker said.
"Apart from that, daytime highs remain at around 21C and 22C."
Overnight temperatures will gradually drop as the week progresses, with a high of 18C expected for Monday, 17C for Tuesday and Wednesday, and 15C for Thursday and Friday.
