For your trip planning
December: warm water, substantially more rain
Compared with November, rainy days and rainfall rise while the daytime high falls and the sea warms slightly. January is wetter still, a little cooler by day and almost identical at sea. December therefore has only a small advantage over January, not a dry-season window.
