Light rain up here in the Southern Namib, the tail end of the cold front currently hitting the Cape… always nice to see…

Interesting that this front reached you, while others didn't. I see a small area of rain (1mm) on the charts, while we are getting 10-25mm:

Whereabouts? The annual average around Cape Town ranges from 450mm at the airport, to 1500mm in Newlands. Orographic effects play a big role in this, and several recent fronts have had relentless wind and rain.

I haven't done a proper calculation for our gauge in Kenilworth (it overflows at 30mm), but it is probably close to your numbers. Our annual average probably falls in the range of 800mm to 1200mm in most years.

I'm close to you, on the other side of the M5.
Not sure of our average rainfall, but I was working on around 600mm for winter (April to September/October).
I know that the closer you go to the mountain side the more rainfall, Kirstenbosch the highest.

Grew up in Rondebosch, bordering Newlands, so I know how hard it can rain in the Cape behind Table Mountain.

My gauge goes to 100, I emptied it out twice this week with 93mm on Tuesday and 95mm on Thursday, with 9mm inbetween.

Dry mid morning here SP side until about an hour ago when it started bucketing down.... the weather Gods have finally more than compensated for a dry May and June... been a while since a recall such continuous spell of inclement weather with rain in CT.

Last year, June was our wettest month in the Cape.
One overnight session produced 80mm.

This winter we've had two overnight (24 hour) periods of over 90mm, and it's still raining.

I agree May and June this year were dry. July is making up for that.

It rained this morning, was meant to rain around now, but blue skies have opened. For what it's worth, I recall similar weather patterns in the eighties, I can remember a massive front that reached all the way up past Henties Bay from the Cape...

What I love is that from Rondebosch the rain almost always comes in along the mountain - can see it moving in as the mountain gets blotted out and countdown till it hits.

We have entered the showery phase of this system (a bit like on Sun 7th). After many days of gloomy but relatively mild temperatures (16C), the wind direction is swinging to SW, and cold upper air is causing convective instability. This will also bring snow overnight into Sun 14th. It will be clearer on Mon 15th, but deteriorate soon after.

Depending on the wind direction, it can be twice as wet in Claremont/Kenilworth as in Rondebosch. The orographic effects of Devil's Peak are much less than the broad mass of Table Mt.

I grew up in Plumstead, where rain also depends on wind direction. I used to work in Newlands, which is always wet in winter.

Some interesting observations.

I'm in Plumstead at the bottom of Wynberg Hill. Measured 38mm so far today, 317mm for the month. The measurement compares well with others around me.
 
Nice double rainbow over False Bay around 16h15.

The barometer is rising quite quickly signifying a bit of relief for the next few fours before the next system arrives. 1009mb last night to 1015 tonight. (23:00)
