History
Regular observations of rainfall were started by the Royal Engineers in 1790 and have continued with only minor interruptions until the present time, this provides the Meteorological Office with one of the oldest and most complete data sets in the whole of the Iberian Peninsula. In the mid thirties the Royal Navy set up an observing station at Windmill Hill to serve the need of the flying boats operating in the Bay of Gibraltar. In 1938 the Meteorological Office took over the responsibility of all observing and forecast services including the supply of weather information to the Combined HQ for the North Africa landings in 1942. At the end of the war in Europe the forecast and observing services were combined in Nissen Hut accommodation moving to the current location in the Air Traffic Control building in May 1955. At present, surface weather observations of temperature, wind, visibility, cloud, sunshine, rainfall and atmospheric pressure are made hourly, and sounding of the upper atmosphere, by radio-sonde balloons is carried out every 12 hours. The Meteorological Office Gibraltar today enjoys high speed satellite data links with its HQ in Bracknell providing services to Aviation, Shipping, Building, Business, Media and Leisure.

Gibraltar's weather is governed by the "Levanter and Poniente", local winds that blow through the Strait from an easterly or westerly direction. In summer, the mainly dry season, the wind from the East or Levanter, brings warm and humid conditions and generates a rather persistent 'Rock Top' cloud that hangs over the city area. Sea fog is not uncommon on these occasions. The Poniente or wind from the West, however brings hot, clear and mostly dry weather. Because of its location, on the edge of Europe, close to Africa and guardian of the Strait, linking the Atlantic and the Mediterranean, Gibraltar is a place of Meteorological extremes. Gibraltar and the immediate Strait area enjoy a unique position lying at the western entrance to the Alboran Basin which is guarded by the Atlas mountain range to the south, and Sierra Nevada to the north. These ranges act as a massive barrier to air entering or leaving the Alboran Basin and consequently, in the Strait Area, the low level air is constrained to flow in mainly easterly or westerly streams. Summer is dry and warm with an average of 10.5 hours of sunshine per day. The summer drought frequently lasts 90 consecutive days. The mean temperature in August is 24.3°C. Winter in Gibraltar can be a mixture of fine, wet and cool weather. On average only 30% of days are classified as 'wet', although rainfall amounts can be variable in the extreme. The mean temperature in January is 13.5°C. The Office is one of the few in the region that is continuously manned for both forecasting and observations. Whilst our main work concentrates on the weather of Gibraltar, nearby Spain and the Straits we are able to provide reliable guidance for up to five days over most of Europe, North Africa and for the Canary Islands.
