How to read this: each of the 51 runs starts from slightly different conditions. If most runs put a week above the normal high, a warm week is likely. If they split, nobody can say yet. The long-range model uses a coarser grid than the daily forecast, so its figures are smoothed: read the signal, not the exact degree. For days 1–16, use the 14-day forecast.
Typical October weather: 23.8°C by day, 17.4°C at night, sea 22.5°C, about 5.5 rain days. Benidorm weather in October.
How far ahead can you trust a forecast?
Day highs for the next three days are usually close. By day 7, misses of a few degrees are common and rain timing is only a rough guide. After about 10 days, a single day-by-day figure is little better than the average for the date. That is why we show a range from 51 model runs beside each day: a narrow range means the models agree, a wide one means wait a few days and check again.
