Bwa’r arch prydnawn,
Tywydd teg a gawn.”
Rainbow in the morning,
Frequent and long showers;
Rainbow in the afternoon,
Fair weather we shall have.
Ceredigion, in “Bye-Gones,” August 2nd, 1905, says: “All along the Merioneth and Cardiganshire Coasts farmers watch the sea carefully in harvest time. If there be not a cloud in the sky; if the wind be in a dry quarter; and if the sea be of cerulean blue, if the margin be discoloured and muddy, the farmers know that rain is approaching and will probably be on them before nightfall.”
If distant mountains are clearly seen, rain may be expected; but if the mountains appear as if they were far off, it is a sign of fine weather.
When the smoke from the chimney falls down toward the ground, instead of rising upward, it is a sign that rainy weather will soon follow; but if the smoke goes upward straight, it is a sign of fair weather.
In the evening, when the horizon in the west is tinged with a ruddy glow it is a sign that fair and dry weather will come.
