Ground Conditions

Reported on Friday, December 05, 2025

Time: At the summit around 0900
Snow above: 950m
Route taken: PyG path
Next report: Tuesday 9-12-25 (may be delayed in case of strong winds)

Snow near summit 5-12-25

Conditions
A little new snow was seen lying on the mountain close to the summit today. Most of the patches of old snow seen on Tuesday were also still present on the mountain.

There were a few very scattered patches of snow on the mountain above about 700m which did not affect walking the path at all, with the slightly more significant patches of snow on the path above 950m.

Above 950m on the PyG and miners paths approaching Bwlch Glas was where this slightly more significant snow was present. It was easy enough to avoid this snow on the path with some care in the less windy conditions that existed earlier this morning, but as only a narrower margin existed without snow in a few places it is possible that this snow could affect walking more significantly in times of strong winds. The snow seen here, although thawing, was hard and compressed in nature.

Above Bwlch Glas on the PyG, miners, Llanberis and Cwellyn (Snowdon Ranger) paths there was more recent thin snow on the mountain and on the path. It was relatively easy to walk the path despite the snow here initially, but there were some places close to the summit where there was some very slippery compacted partially thawed and re-frozen snow, and care was needed to walk it safely. The snow here was also gradually melting during the observations, and further thawing seems likely in the coming days (see Additional Information below).

A cloudy and misty morning, opening up, and strong winds picking up during the morning, before afternoon rain.

Essential equipment
Suitable seasonal walking equipment, including lighting (such as a head torch or two each).

Although it is likely that technical winter equipment will not be needed in the coming days, carrying microspikes just in case could offer options if some patches remain on the mountain for a while in the coming days.

Additional Information
On the Friday of the report the forecast suggests that the temperature on the summit will rise above freezing later on Friday, remaining above freezing throughout the period until the next planned report on Tuesday. The temperature at the summit is forecast to be as low as 3ºC (feeling like it is as low as -7ºC at times).

While temperatures remain above freezing any new snow or ice is unlikely, and the snow that was present today will continue to thaw. It is worth keeping an eye on the latest forecasts in case this changes unexpectedly.

Although snowy and icy conditions are not likely in the coming days, periods of strong winds are forecast. These strong winds could mean that it will be safer to postpone the day of the next report (possibly until Wednesday when slightly less strong winds are forecast). The windy and wet conditions will continue to make it feel very cold even at times when the temperature at the summit is several degrees above freezing.
