Daytime and night-time in September
The typical September day in Nerja peaks at 26.6°C, but that is an average: the warmest 10% of days reach 29.4°C or more. About 76% of days top 25°C and 1 in 14 pass 30°C. Nights average 20.4°C; one night in ten drops to 17.7°C or lower, so pack a layer for evenings. Between 1991 and 2020 the hottest September day here reached 36.7°C (2016-09-05) and the coldest night 13.7°C (1994-09-23).
Rain in September
Dry (3 rainy days or fewer): about 3 days with 1 mm or more, 18 mm in total. Year to year it varies a lot - the wettest September was 2012 with 66 mm, the driest 2002 with 1 mm. Humidity averages 70%.

Warm enough for summer clothes, but plan around midday
September still feels like a hot-weather month rather than a cool autumn break. Days reach 25°C on 76% of occasions, so light clothing is a sensible default, though it is not a promise for every day. Only 7% reach 30°C, making that level of heat possible rather than typical. Put more active plans towards the morning or later afternoon, and leave room for shade at midday. Average nights are mild enough that heavy layers are unlikely to earn their luggage space. A light extra layer is sensible, though: the coolest nights can fall to around 18°C or below. This suits travellers who like warmth but do not need intense heat throughout their stay.
Mostly dry weather with plenty of time outside
Rain is a relatively small risk to outdoor plans, with about 3 rainy days across the month, but a dry holiday is not guaranteed. Keep plans flexible rather than packing as though showers are impossible. Around 8.4 hours of sunshine within 12.2 hours of daylight leaves plenty of scope for swimming, relaxed lunches and time outside; it does not mean clear skies from morning to evening. Sun protection still belongs in your day bag. The sea is warm enough for swimming on average, making September a reasonable choice if water time matters as much as air temperature. The balance favours travellers happy to mix swimming with breaks in the shade, rather than those seeking cool conditions for sustained activity.
