Ground Conditions

Reported on Friday, December 12, 2025

Time: At the summit around 1000
Snow above: no snow
Route taken: PyG path
Next report: Tuesday 16-12-25

No Snow 12-12-25

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

One small patch of snow was seen holding holding on to the upper slopes of Garnedd Ugain.

A cloudy morning with a light breeze, and the odd sunny spell.

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

Additional Information
On the Friday 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 Tuesday. 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 point the possibility is not far off at times, especially on Tuesday morning (with the possibility of a period of freezing on Tuesday night as well). 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.

Periods of strong winds and heavy rain are also forecast, with the wind getting strong by Saturday afternoon, and continuing into the start of the week.
