Out and About on Ben Nevis
9th March 2026
Another relatively benign day in Lochaber today with the freezing level again fluctuating around the higher summits. The snowpack is now well consolidated throughout. There were fair few climbers out, and there looks to be a reasonable amount of ice surviving at higher levels on Ben Nevis. However, I don’t know anything about the quality of that ice.
Some photos to show conditions below, and then a few temperature graphs and tables looking at the January and February temperature.
Two cheery climbers to whom I was chatting on the walk in. There were a good number of climbers out today which is good to see. I don’t have any numbers, but it feels like there have been more people out climbing and mountaineering this season as compared to the previous couple of seasons. Conditions have been better this season, so it makes sense that more people have been getting out.
Looking over to Carn Mor Dearg. The South-East winds earlier in the winter filled in the West face. However, the snowpack has been retreating in the mild conditions of late.
North-East Buttress to Tower Ridge.
Looking up Observatory Gully. A couple of climber can be seen on Point Five Gully if you know where to look; one person belaying at the base of the second pitch, and another about 10 metres above that.
The Hadrian’s Wall/Point Five Gully area. Thanks to Tom Lawfield for the photo.
Looking into Coire na Ciste.
The Aonach Mor Midday Summit Temperature for each January and February since 2008. The left hand chart shows the data ordered chronologically, the right hand chart shows it ranked coldest to warmest with this year marked in yellow. This January was 4th coldest out of those 19 years, and February the 9th coldest. They were 0.6°C and 0.4°C below the mean for January and February respectively.
The January Aonach Mor midday summit temperature anomaly. This year had a small negative anomaly. The cold Januarys of 2010 and 2021 and warm January of 2020 stick out. Interestingly, no January in this time has had an anomaly of ±2°C or greater
The temperature anomaly for February for the last 19 years. This year had a small negative anomaly. Interesting February had 5 years (2008, 2010, 2018, 2019 and 2023) during which the anomaly was greater than ±2°C. During the same period January had no years when the anomaly was that large. In terms of mean monthly temperature February has been a more variable month than January. I am not sure the reason for this, or if the day to day temperature change in February is greater than in January. Something else to look into at some point.
