Days 1–10: a high-resolution global weather model (0.25° grid), adjusted to this place's own climate so that a hill village is not given the valley's warmth. New model runs arrive twice a day.
Days 11–34: the average of the 31 runs of a global ensemble model. Day-to-day weather cannot be forecast this far ahead, so read these days as a trend — warmer or colder, wetter or drier than usual — and check again closer to the date.
