In my experience so far, January is usually the worst month when it comes to real hiking. It’s usually around zero, which means the uncomfortable mix of snow and mud. There were a few years when mid-February was quite a cold wave – 2006 comes to my mind, when the temperature remained around -20°C day and night for great part of the month, the lowest temperature here in the city being around -25°C during day. Or it’s not as cold, but there’s cold and strong wind. The unpredictability means that for hikes planned by the club, it’s usually short walk near the city where it’s not that hard to make some last-minute adjustments. And it was long before I decided to go out alone in this month.
