Areas of Snow 18-2-2025

Conditions
There has been a significant thaw on the mountain since the previous report, but despite this there are still areas of snow, affecting walking on the paths in many places. The snow and ice is quite patchy for the most part, starting at a height of around 800m.

Most of the snow observed is by now very hard and icy in nature, but thawing gradually across the mountain, with the temperature on the summit just at the freezing point. The snow that was thawing was still hard and icy, with a softer surface in some places, this surface was loose, sugary and uncertain in other places and compacted and slippery in areas higher on the mountain.

On the PyG and miners' paths there was pure ice on the route above about 800m. These patches of ice were easy to avoid at first, becoming more extensive and harder to avoid as you went higher up, until old snow covered the path rather than ice below Bwlch Glas. There is still a significant area of thick old snow covering the path below Bwlch Glas on the PyG and miners' paths where the path crosses consequential steep slopes. There were some slippery areas here with the path confined and narrow, and it could become more slippery as it thaws further during the week. Anyone who wants to avoid accidents when traversing the miners' and PyG's paths through this area will carry dedicated winter mountaineering equipment (see Essential Equipment below) in order to be able to choose a safer way to travel the path to Bwlch Glas and therefore the summit along these routes.

Between Bwlch Glas and the summit on the Cwellyn (Snowdon Ranger), Llanberis, the miners and PyG paths there were areas of compacted snow which were icy and slippery to walk on in places, and required considerable care to travel safely.

Although there was considerable snow on the Llanberis path, especially from the upper reaches of Allt Goch (around 900m), it did not cover the path completely at any point before reaching Bwlch Glas. While there was a strip without snow or ice along the path, it was narrow enough to make passing walkers coming in the opposite direction quite awkward, and the surface of the path was quite muddy in some places too. Although this does not look likely from the forecast on the day of the report any re-freezing could make walking the route difficult (see Additional Information below), and you should look out for any periods where the temperature is forecast to be below freezing (especially overnight the night before, or long periods of clear skies overnight). While the Llanberis route is unfrozen it will offer a choice that is much more likely to be possible to travel more safely compared to the PyG path or the miners' path for anyone without winter mountaineering equipment (with the Cwellyn (Snowdon Ranger) path also likely to be an even more reasonable choice), although carrying microspikes could be helpful for anyone having trouble with the icy areas near the summit.

No part of the path was walked for further information, but a fairly significant patch of snow was seen on the upper part of the Watkin path as it joins the Rhyd Ddu path above Bwlch Main, and it seems that this snow was causing considerable difficulties for walkers on the path without dedicated winter mountaineering equipment.

A fine day with light or moderate winds on the whole, but the wind swirling around the summit, and increaseing in the afternoon.

Essential equipment
Seasonally appropriate walking gear, including lighting (such as a headtorch or two).

Carrying an ice axe and mountaineering crampons will give you options to stay safe on the mountain. This is specifically relevant to the PyG and miners' paths, or any other route where significant patches of snow completely cover the path in places. There may be routes where they are not needed, but carrying microspikes could offer options when encountering slippery areas on routes where there is less snow.

Additional Information
On the Tuesday of the report the forecast suggests that the temperature on the summit will be close to freezing initially, rising several degrees above freezing later in the week, with a significant thaw likely on Thursday and Friday in the strong winds and wet spells. The temperature at the summit is forecast to be as low as 0˚C, feeling as low as -10˚C at times, and it will continue to feel very cold in the wind and rain even when the temperature is several degrees above freezing.

On the day of the report any new snow or ice looks unlikely from the forecast, with any lying snow most likely to be icy on Wednesday morning after a relatively cold night on Tuesday night. After this any snow is likely to thaw, but is likely to persist in places, being wet and slippery in nature as it thaws.
