Ground Conditions

Reported on Wednesday, December 10, 2025

Time: At the summit around 1500
Snow above: no snow
Route taken: PyG path
Next report: Friday 12-12-25

No Snow 10-12-25

Conditions
This report has been published a day later than the usual Tuesday due to very windy conditions on Tuesday 9th December. This change was made for safety on the mountain, as well as to make fuller observations possible.

No significant snow or ice was observed during today's observations and the paths were completely clear.

Two small patches of snow were seen holding on to the upper slopes of Garnedd Ugain, but they were not an obstacle of any kind on the mountain.

A cloudy and windy afternoon, and although a few streams were still flowing full the paths were surprisingly dry after yesterday's deluge.

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

Additional Information
On the Wednesday of the report the forecast suggests that the temperature on the summit will remain above, or close to, freezing for the period until the next report on Friday. The temperature at the summit is forecast to be as low as 0ºC (feeling like it is as low as -7ºC at times).

While the temperature remains above freezing any new snow or ice is unlikely, but with the temperature at the summit close to, or reaching freezing the possibility is not very far away at times, especially on Friday morning. You should keep an eye on the latest forecasts for full information, keeping an eye out for periods when the temperature is below freezing on the summit before, during or immediately after the time you intend to travel on the mountain. Carrying microspikes just in case could provide options if such freezing periods develop.
