"Nobody on the road/Nobody on the beach/I feel it in the air/The summer's out of reach" - Don Henley, "Boys of Summer" "The summer still doth tend upon my state" - Titania in A Midsummer's Night Dream by William Shakespeare "May the road always rise to meet you, May the wind always be at your back, May the sun shine warm upon your face" - Pilgrim's Blessing "Set the controls for the heart of the sun" - Roger Waters, Pink Floyd Most people set off a week or so before Christmas, and return early in the New Year.

Mauritius rumours The voluptuous island is not at its climatic best in the next week or two: you can expect strong south-easterly winds and a fair amount of cloud and rain.

Happily, the Northern Hemisphere's midwinter gloom enjoys an equal and opposite phenomenon south of the equator. From the beaches of Rio and the Western Cape to the wilderness of Tasmania and New Zealand's South Island, 21 December will be the longest day.
