Cuenca weather in September

Forum posters describe Cuenca's roughly 8,400-foot elevation and near-equatorial location as producing genuinely fast-changing weather essentially year-round, September included - bright sunshine can give way to a hail or rain shower within an hour, and back again. Posters consistently recommend light layers that work as both sun protection during the day and a barrier against the evening chill, since temperatures drop noticeably fast around sunset (roughly 6:30pm). Average highs stay fairly consistent across the year at around 70F with lows near 50F, so September doesn't represent a dramatically different month climate-wise from the rest of the year - the defining feature is the day-to-day and hour-to-hour unpredictability rather than a distinct seasonal shift.

Forum advice for the Sierra region in March lines up closely with Cuenca's own numbers: sunny mornings giving way to overcast, showery afternoons, with nights cool enough to want a sweater (around 50-55F) and days comfortable in a light jacket (mid-60s F). Cuenca's high elevation means it rarely gets properly hot even at midday. Multiple posters recommended packing in layers and always carrying a light rain jacket, since a clear morning can turn into an afternoon shower with almost no warning - locals just wait it out under a café awning rather than change plans.
