I received an excited call from a colleague on Wednesday evening saying that I should really look outside and take a photo of the setting sun. So I grabbed my camera, drove to a viewpoint, and snapped this beautifully cloudy red sunset (click the photo to see the big version).
The following day's weather was terrible - it rained buckets in the morning. This led me to think of the saying, and how it should have been a "sailor's delight". Today, Friday, I type this post as the sun is setting. The sky is again a brilliant red hue, so I just took a look at WeatherSA and guess what I found? Saturday:"Cloudy, rain mainly afternoon (60%)"!
So I'm thinking that perhaps the saying should go "red sky at night (in Cape Town), sailor's warning, red sky in the morning (in Cape Town) sailor's delight". Our red-sky mornings really do turn into beautiful days. :)
