This page shows 16 days ahead, refreshed every hour. It blends ECMWF, NOAA GFS and whichever national high-resolution model covers San Martín 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.
