Is Cape Town’s drought coming to an end?

Figure 1

I’ve just been looking back at the rainfall statistics for Cape Town which as you probably know is suffering its worst drought since at least 1933. They knock out a good SYNOP at Cape Town international airport, so it wasn’t that difficult to add up the 24 hour rainfall totals to find that in the last 12 months 266.2 mm of rain has fallen there (fig 1). That doesn’t sound too bad on the face of it, but in the last five months, that’s since the start of November, there has been only 51.7 mm of rain.

The climate here is pretty equable as you can see from the six hourly temperatures for the last year (fig 2).

Apparently Day Zero, the day when water runs out completely, and which was expected to occur this April, has now been pushed back to 2019. Let’s hope (no pun intended) that the 6 mm of rain that fell in the last week is an omen of a wet winter to come for Cape Town’s sake.
