Nope, that is ‰. The degree symbol is Alt 0176 (must use the numeric keypad too).

not on my side ... been using Alt167 for donkey years ... and sorry I said 137 ... meant to type 167

but alt137 gives me ë

Some weather reports saying 60mm tomorrow, others almost none....

Can you be more specific? I don't see anything significant for tomorrow (Wed 23rd).

YR, shows


Meteoblue and Windy show


Very bizarre, but YR has become very unreliable for my use in recent years

False Bay last night (supposedly - for all the everything is AI crowd)

SABC news reports 100 houses damaged at 4am this morning in Mitchell's Plain, due to strong winds, rain and hail!?

Yeah, no. That's a bug. Stick to the main city forecasts. There is really no difference between model points so closely spaced together, and sometimes you get bogus information, or the 'wrong' location.

P.S. A few years ago my brother was checking the weather for a wedding in Noordhoek, and got completely wrong information...

Place: Noordhoek (Farm)
Region: Namakwa District Municipality, Northern Cape, South Africa

Rather watch the weather ladies, they are usually right:

Look carefully at the place you have chosen:

Section of populated place, City of Cape Town, Western Cape (Republic of South Africa), elevation 246 m

The elevation of 246m above sea-level is not a 'normal' forecast, and involves significant orographic enhancement. Sometimes yr.no is better, but in this case clearly not...

Always, always, cross check the reasonableness of a forecast! When in doubt check Robben Island, which has no hills or mountains. Yr.no shows 0.1mm on Wed 23rd:

Long term weather forecast for Robben Island

Weather forecast for Robben Island for the next 10 days.

OK, a weather friend has clarified what is 'wrong'. All of the yr.no forecasts use a model called the EURO. The chart for tomorrow has this anomalous patch of rain centered over Cape Town, which does not match any sense of reality IMO:

Yr.no 's prediction now showing 36mm for tomorrow. 2 hours ago or so it showed 10mm for Wednesday, and 10mm for Thursday. Chop and changing the whole time.

See my post above. Sometimes models get it wrong, and sometimes models get bad data, and sometimes they swallow their own tail. I can't see which it is, but I will eat my hat if that forecast is anywhere near reality...

Dunno what all the weather stuff means but I can tell you now.. my butt crack is soaked in sweat bru

Sure that's not from the lube!?

Well, I get the same result if I choose Bellville or Durbanville as well. Don't really understand the point of looking at the weather for Robben Island if I want to know if I can braai.
But anyway, meteoblue and windy is spot on, even with the elevation.
Yr seems to be getting it more wrong than right these days, at least the places I go.

Sometimes forecasts are wrong, and you have to use common sense, and not rely on a single forecast from a single provider. I don't think yr.no is any better or worse than other sources. For a while it had an exaggerated reputation. This is just balancing out the accuracy, or lack thereof...
