When is it best—and worst—to pay a call on the Irish capital? The summer offers a real lift, as the natives spill out of the pubs into the slew of sidewalk cafés and open-air restaurants. The week around St. Patrick's Day (March 17) is, naturally, a nonstop festival of parades, cultural happenings, and "hooleys" (long nights of partying) throughout the city. Christmas in Dublin seems to last a month, and the city's old-style illuminations match the genteel, warm mood of the locals. The downside quickly follows, however, for January and February are damp hangover months. A warm sweater is a must all year round, as even summer nights can occasionally get chilly. Dublin gets its share of rain (though a lot less than other parts of Ireland), so an umbrella is a good investment—and best to make it a strong one, as the winds show no mercy to cheaper models.
The most appealing thing about Dublin isn't the sights, or even the great pubs and restaurants. It's the people—the citizens, the Dubs. They're fun, funny, and irreverent, and most of them love nothing better than talking to strangers. So, to get the most out of your visit, make a point of rubbing elbows with the locals. The pub is a natural spot to do this, but almost any place will do. Ask for directions on a street corner (even if you don't need them), and you might be on your way to a brilliant conversation.
And mind the slag. "Slagging" is the Dubliner's favorite type of humor. It consists of mildly—or not so mildly—insulting a friend or a soon-to-be-friend in sharp but jovial fashion. It's best employed to deflate vanity or hubris, but clearly marks out the victim as well-liked and worthy. Packed buses and late-night chip shops are classic slagging venues.
