This weather condition is perfect for smaller excursions, such as exploring towns in the Adriatic area:
If your excursion to Portogruaro - a town in the Venetian Gothic style - falls on a Thursday, you're in luck because Thursday is market day. Chance for good bargains. Apart from sightseeing through this beautiful town you can settle in the Bar Roma (just on the Piazza) with a cool drink or delicious appetizers.
Under the Basilica of Concordia (in the center of the town, you can not miss it) excavations were uncovered, which one may visit for free. After this cultural experience you can relax with a chilled glass of Sauvignon from the Collio and fried mini fish (fantastico!) (Russiz Superiore!) at Gigi's (officially: Hostaria da Fanio, diagonally across the front of the basilica, the left-side bit hidden).
Incidentally, in Concordia Monday is market day.
A small town in the midst of almost magical hills (a trip to this area is definitely worth it, simply because it is so beautiful). And if you are lucky (in this particular case, every 2 years in September), you can witness the most unusual game of chess in Italy in Marostica.
