How accurate is a 15-day forecast?

Weather models are reliable for the first few days, but small errors grow over time. That is why every day on this page is marked: days 1–3 are reliable, days 4–7 moderately so, and from day 8 onwards the forecast shows the direction of travel – a warmer or cooler spell, a wetter period – rather than the exact temperature of a given day.
