Some years ago, a friend told me that when clouds first start appearing in the clear summer skies in Cyprus, it means that the first rain of the autumn will come in about six weeks' time. In subsequent years I took note, and found this was not far out.
In the last week, we've had a few clouds in the sky, and last night around 5pm the sky looked distinctly un-Cypriot:
So, maybe it might rain in mid-September? It would be wonderful if it did, as the drought is getting quite serious.
