Ten Tors

This weekend sees the 2015 Ten Tors challenge and once again, the Met Office will be providing tailored forecasts for the organisers to help with event planning and coordination. This year, for the first time, an Operational Meteorologist will also be at Okehampton Camp for the weekend, providing the latest information on weather conditions across Dartmoor throughout the event to help the organisers make the necessary decisions to keep the teams safe.


Chief forecaster Dan Suri said “The event may start on rather a wet note, with some heavy showers likely on Saturday morning”. These showers will clear later in the morning leaving a drier and brighter afternoon. It will be breezy too, making it feel quite chilly in the wind. Saturday night will be largely dry, but it is likely to become murky through the early hours of Sunday, with occasional drizzle and hill fog. The cloud base will probably lift a little during Sunday morning, but higher parts of the Moor are likely to stay murky, and whilst the odd brighter spell may develop with shelter from the wind, it will remain largely cloudy. Still quite breezy on Sunday too.

The challenge

The weather plays a major part in the successful completion of the event for everyone taking part. Around 400 teams of six take part in the challenge to complete the course. There are three different course lengths, depending on the age and ability of the team:

  • 35 miles
  • 45 miles
  • 55 miles.

The idea of the challenge is for the teenagers to become self-sufficient for the weekend – carrying everything they’ll need for the trek and making their own decisions.

At this time of year, conditions can be varied, from torrential rain to hot sunshine.
