And at 20, 25 or 30 days? No model seriously forecasts that far: beyond two weeks, only the local climatology gives a reliable trend.

Frequently asked questions

Are these 15-day forecasts reliable?

Reliability decreases with the horizon: excellent at 3 days, good up to 7, indicative beyond 10. Each passing day sharpens the rest.

Can the weather be forecast a month ahead?

No, not day by day. That is why this page completes the 16 forecast days with the MeteoSwiss monthly norms for Walenstadt: the most honest estimate beyond two weeks.
