Traveller notes on Gibraltar in September
Other months in Gibraltar
May in Gibraltar comes in around 23°C — the forum's phrase is warm enough to sunbathe but not so scorching that you cannot comfortably do the Rock, which is rather the point of timing a visit here. Rain is possible but May is usually fine, with only a handful of wet days. The local phenomenon worth knowing is the levanter: a cloud that forms when hot air off Africa rises and condenses against the Rock. It is not a rain cloud, and it typically either burns off by early afternoon or sits for a couple of days — but while it is there, the view from the top is gone.

Cruise calls
1 Apr – 31 Oct · usuallyCruise seasonCrowdedAround two hundred and fifty ships a year berth on the western arm, and on a two-ship day Main Street and the cable car queue belong to them until the middle of the afternoon. The schedule is published months ahead. Source ↗
- Nature
Dolphins in the bay
1 Apr – 30 Sep · usuallyWhale seasonThree species work the bay year-round and the boats out of Marina Bay run several trips a day through the summer. Sailings thin out in winter and are called off outright on a hard Levanter. Source ↗

The Levanter cloud
1 May – 30 Sep · usuallyWind seasonRiskWhen the easterly blows, damp air piles against the Rock and a banner of cloud sits on the ridge for days. It ruins the view from the top and diverts flights to Malaga.
- Season
Summer border queues
1 Jul – 5 SepSchool holidaysCrowdedThe land frontier with Spain can take up to two hours to cross by car in high summer and on Spanish holiday weekends. Parking on the La Linea side and walking across is what residents do. Source ↗
- Nature
Raptor migration over the Strait
20 Aug – 31 Oct · usuallyWildlife seasonStorks, honey buzzards and eagles funnel over the Strait in autumn to make the shortest crossing to Africa, and on a good easterly morning they pass low over the Upper Rock in thousands.
- Holiday
Gibraltar National Day
