How accurate is the Haystack forecast, and how far ahead does it go?

This page shows 16 days ahead, refreshed every hour. It blends ECMWF, NOAA GFS and whichever national high-resolution model covers Haystack best. The first three days are the dependable part - day one is usually within a degree or two - and accuracy falls off steadily after day five, so read the far end as a trend rather than a plan. We publish our measured error against real station observations on the accuracy page.
