Additional weather information
Meteorologist's view
Warm temperatures - notably a few degrees higher than Monday - bring a risk of dehydration and heat stress, especially on long climbs. Despite some cloud cover UV-levels will remain high, so appropriate sun-protection is recommended.
Weather
A dry and bright day and a few degrees warmer than Monday. Plenty of prolonged bright or sunny spells, but high-level cloud will turn the sunshine hazy at times. Chance of a few showers later in the day.
Chance of cloud-free hill tops
90% or higher.
Low cloud and visibility
Summits clear and good or excellent visibilities for the majority of the day. The odd mist or fog patch may form in valleys in the early hours, lifting and breaking soon after dawn. Visibilities may fall temporarily moderate or poor should any showers pass through.

No recent ground conditions report available.
