Forecast questions

Can I plan a trip on a two-week forecast?

The first week is solid for planning. The second week shows the trend — go by the averages and the comparison with the climate normal, and check again closer to the date.

What does the "vs average" column mean?

It is the difference between the forecast and the climate average for the same dates in Merthyr Tewdrig, calculated from 60 years of observations. A plus means the week is warmer than usual.

Why are weekends shown separately?

Saturday and Sunday plans are what people ask about most, so we break them out as separate cards with temperature and rainfall.
