Detailed answer

Temperatures

The average daily high in October is 22.5°C and the average low is 17.3°C, based on 1991 to 2020 records at Gibraltar Airport. Older German Weather Service records for 1961 to 1990 are very close.

Rain and sunshine

October averages around 85 mm of rain over about 6 days with 1 mm or more, though totals vary a lot from year to year. Sunshine averages about 6.4 hours a day.

What October is like

October is usually the last warm month. Early October often feels like late summer, while later in the month the first autumn rain arrives. The sea is still around 21°C, so a swim is possible on calm days.

The Levanter, the easterly wind that brings a lasting cloud over the Rock, is most frequent between April and October, so a grey, humid cap over the Rock is still common.

Wind

Gibraltar's weather is shaped by two local winds through the Strait: the Levanter from the east, which brings humid air and cloud over the Rock, and the Poniente from the west, which brings clearer, drier weather. Strong winds around the Rock can make flights divert to Malaga.

What to wear

Pack summer clothes with a light jacket or jumper for evenings, plus a compact umbrella. Comfortable walking shoes matter more than anything else if you plan to walk the Upper Rock.
