Moments after being caught in a shower. The rainbow was a complete semi-circle but the camera lens was not wide enough to fit it all in. One of those magic moments.
A rainbow at night,
Fair weather in sight.
A rainbow at morn,
Fair weather all gorn.
Ok, not the best of poems and seemingly a take on the “Red sky at night, shepherd’s delight” folklore but the logic behind both poems is the same. Assuming a southwesterly prevailing wind a rainbow at night, i.e. late afternoon, will be in the east so the rain will have passed. A rainbow in the morning will be in the west and will have yet to reach us.
This photo is late afternoon and looking northeast and sure enough, the rest of the day has been just grand.
