From Madrid I am going South and West to Portugal then North and East back to Madrid. What should I expect in weather and how should I pack?
Some lightweight raingear might come in handy (I carry an Eddie Bauer Nylon Rain Parka). In general, March weather is cool (highs 16-20 Celsius (60's F)) with some showery activity. It may be windy on the Portugal coast - another use for that nylon rain parka.
BTW
MAD for Madrid: 10 Celsius is
50Farenheit, not 40.
