08Editor's notes
What the numbers don't tell you
October brings the Theatre Festival for two weeks, the Bram Stoker Festival over Halloween weekend with parades and light shows, and the October bank holiday on the last Monday. Days are cool, around 14 °C, and wet, with rain on about ten days, and the clocks go back on the last Sunday. Hotel rates drop, and autumn colours fill Phoenix Park and the Botanic Gardens.
The Dublin Marathon on the bank holiday weekend closes central roads for a Sunday morning, with 20,000 runners. Rugby's Champions Cup and the Leinster home games fill the Aviva and the RDS. Daylight drops below ten hours by month-end. For the darkest, cheapest weeks before Christmas, see November.
