The record low in the city is the coldest since 1901, very close to the all-time low.
NE winds and High pressure was in controll several periods during the month, giving us very cold lows but also sunny days. Edit: March was not colder than Feb. No data for the upgraded Lade  station for Jan, so Værnes is used that month.
Now we have two very cold months in a row. When will we get some deserved above avg weather?

April snow seems unusually early for your climate and latitude. Has there ever been any snow fall in January/February? The wikipedia box shows 0.1 snow days for January and 0.2 for February (and March).

Highs were below average and lows above so it ended up finishing bang on average for the month. It was a very snowy month.

I'm guessing it has to do with the altitude. If you have two climates with the same average temperature but one is located higher than the other, the higher altitude climate will experience more snow.

I've never seen snow in January nor February.

I. Aye, certainly true! Oberon's winters are averaged in such a way that it makes it look warmer than it really is; despite average winter highs of 7°-8° C according to documentation, there are many days not in excess of 3° C (with some ice-days); the averages are such due to the odd 10° C days that arrive with plentiful sunshine—this is what balances it. Of course, winter averages were much cooler back in the 19th century, particularly the severe winters of 1836 & 1900.

II. Contrarywise to your climate, snow has fallen about five times since 1893 in summer up here, most recently on 5th December 2013; www.blackheathweather.com/pastfalls.html
