In James Joyce’s Ulysses, the events of Bloomsday are so carefully worked out that even incidents of weather can be recognized across the various episodes. Episode 1, at the tower:
A cloud began to cover the sun slowly, wholly, shadowing the bay in deeper green.
In Episode 4, Bloom notices the same thing as he walks home from Dlugacz’s shop:
A cloud began to cover the sun slowly, wholly. Grey. Far.
Four paragraphs later the cloud has passed:
Quick warm sunlight came running from Berkeley road, swiftly, in slim sandals, along the brightening footpath.
And back at the tower it passes as well:
Stephen, still trembling at his soul’s cry, heard warm running sunlight and in the air behind him friendly words.
“The breeze is therefore approximately from the west, that being the prevailing direction of winds in the British Isles,” observes Ian Gunn in James Joyce’s Dublin (2004).
