Mountain Forecast: Wind, Freezing Level and Storms

In groups, students interpret real or adapted mountain forecasts (summit winds, freezing level, chance of thunderstorms, wind chill and cloud cover) and decide whether a planned route goes ahead, changes or is postponed. The focus is on reading data critically and making reasoned decisions.

How to play

1. Explain the key parameters of a mountain forecast and how wind lowers the feels-like temperature, using a simple chart (6 min).
2. Groups of four: each gets a route sheet (schedule, maximum elevation, exposed sections) and three forecasts for three different days (2 min).
3. Analysis: for each day, the group works out the wind chill at the summit, finds when the storm risk peaks and compares it with the route schedule (10 min).
4. Decision: the group chooses to go, adjust (start time, route or turnaround point) or postpone, and writes two data-based reasons (5 min).
5. Reveal: the teacher shares what actually happened each day and groups defend their decision in one minute (5 min).
6. Wrap-up: as a class, agree on three sky signs that mean it is time to turn back (2 min).

Rules

• Every decision must rest on at least two pieces of forecast data.
• Everyone in the group gives an opinion before deciding.
• If there is reasonable doubt about safety, the default is the most conservative option.
• Tablets are used only to look up the assigned sources.

Variations

Adaptations

• Visual impairment: sheets are in large print and data are read aloud within the group.
• Dyslexia: receives forecasts as icons and tables with little text.
• Autism: has a defined role in the group, such as wind chill calculator.

Learning goals

• Interpret the main parameters of a mountain weather forecast.
• Make reasoned safety decisions based on data.
• Adopt a cautious, responsible attitude when planning outdoor activities.

Equipment for a class of 25

• worksheets: 30
• tablets or phones: 8

Teacher tip

Use past forecasts from a familiar area so you can tell students what really happened. Stress that turning back in time is a technical decision, not a failure.
