Sorry to here this, I love Portugal and the weather in early autumn is generally very pleasant. If fun things pall perhaps you could take some time out and watch the (Portuguese) world go round. I love to sit in tea shops and the lovely squares and watch the Portuguese make a not very convincing stab at the working day over cards with tea, coffee and delicious cakes and pastries.

JT is right about the vino though - the white port is my poison, delicious, but strong.
