The local saying
Icelanders say: “if you don’t like the weather, wait five minutes.” It’s true literally often enough that it’s worth taking as planning advice.
Practical implications
- Bring layers. A waterproof shell is not optional.
- Don’t fix a single fragile plan to a single day. Always have a back-up indoor option.
- Check the forecast the morning of your activity, not just the night before.
- Take warnings seriously. Iceland’s weather can kill people who shrug off “a bit of wind.”
