Clothing layers for the forecast

The calculator needs JavaScript. The worked example, sum and figures below show exactly how it works, so you can do it yourself. A guide, not advice.
Short answer
Choose how the forecast feels for your group and whether rain or wind is expected. The tool gives you a packing prompt for removable layers, waterproofs and spares. Comfort varies and forecasts change, so check the latest forecast and official warnings before travelling.

Forecasts change and comfort varies. This is a packing prompt, not a weather safety decision; follow official warnings and change plans if needed.
Our figures (adjustable)
These are our planning allowances and, once checked, typical figures with their sources. They aren't facts about your kit: change any of them in the calculator.
This calculator has no built-in defaults: every figure comes from you or your kit's own label.

FAQs
What layers should I take camping?
Pack removable layers so you can adjust to changing conditions, plus waterproof protection when rain is forecast. Consider spare dry clothes and check the forecast again before setting off.
Does this tell me whether the weather is safe?
No. It is a clothing prompt only. Follow official warnings and change plans if conditions are unsuitable.
