In a week's time I'm going to be setting off to sail on a tall ship from
Gibraltar to Madeira. I have no idea what the weather is likely to be,
except vague tourist-friendly spiel about the lovely weather on the
island itself.

Can anyone recommend somewhere that I might find out typical (or even
forecast, now we're getting closer) conditions for that part of the
Atlantic, both day and night. I want to work out what clothes to pack.

I realise this isn't a "scientific" question, so apologies if it falls
totally outside the bounds of the group.

Thanks,

Pete
