08Editor's notes
What the numbers don't tell you
January is dark, chilly and damp, with afternoons around 8 °C and daylight from half past eight to half past four, but TradFest fills Temple Bar's pubs and churches with traditional music in the last week, and the January sales run all month. It is the cheapest month for hotels, and the National Museum, the National Gallery and Trinity's Book of Kells are uncrowded. Rain falls on about twelve days.
New Year's Day is a holiday; the first Monday of February follows as St Brigid's Day. Frost is occasional, snow rare. The Dublin Bay coastal walk from Howth to Dún Laoghaire is bracing but bright on clear days. Pubs run reduced hours in the first week after the Christmas rush. For the Six Nations and the film festival, see February.
