November is April in reverse. The Southern Hemisphere is winding down, so the swell that ran all season arrives less often, and by the last two weeks the north-east trades are re-establishing themselves and the coast starts behaving like January again.
That is a middling month on paper and a genuinely mixed one in practice: the first half can still deliver a proper south-west swell, and the second half is clean, small and offshore. The rain stops before the month does. The water is at 28°C. On the Caribbean side the opposite is happening, and December to March is that coast's season.
