easterly trades in the T&C have a bit of northerly component in the winter. More later in the winter and usually
blow harder later in the winter.
When a cold front comes down from our friends up north, IF it makes it as far as the T&C then the winds will shift and clock around the compass
to south, west and north, returning to E - NE when the front passes.
Some fronts don't make it that far south and you never see them. Some fronts get that far and stall over you for days and days and you end up with strong north winds until the tropical patterns eventually return. Also some fronts are weaker than others and may just show a reduction the strength of the easterly winds and never shift to the north.
So, I guess I would say there is no "normal" cold front. Just like snowflakes every one is different but you do see some general patterns. However, planning a trip don't depend on the general patterns, try to analyze the specific front you will have to deal with.
