Lisboa The Port of Lisbon is the principal port of Portugal. Lisbon is situated on the north bank of the Tagus River (Rio Tejo) . The harbor facilities are located on both the north (primary) and south side of an eight mile long and one mile wide channel extending eastward and then northeastward from the mouth of the River. The River is navigable by ocean going vessels to just above Lisbon.Lisbon offers excellent protection to ships within the harbor.

Spring : Hazardous weather conditions are rare during the spring. Frontal activity decreases in frequency and intensity. Thunderstorms are more likely in spring and autumn and least likely in summer.
Summer: During the summer months the Azores high is usually located in its most northerly position with a ridge of high pressure extending over the Bay of Biscay and the northern portion of the Iberian Peninsula. The thermal low over northwest Africa and southern Spain is well developed. This synoptic situation produces a northerly flow of air over Portugal with anti-cyclonic curvature. Frontal passages are relatively infrequent, and the few fronts that do pass Lisbon during the summer are very weak. The summer conditions extend well into the fall months of September and October. Northwest winds are more frequent in maritime summer (April-September) and are generally associated with the "nortada" sea breeze. The west or northwest sea breeze in the afternoon combines with the northwest wind produced by the Azores High to set up the nortada (16-21 kt sustained winds) along the western coastline.
Autumn: The autumn transition season is short. The winter frontal passage pattern is usually well established by the end of October. Normally, once the first frontal passage is experienced, the winter pattern is in control and the winter frequency of frontal passage is quickly established.
Winter: Frontal passages are fairly common. However, it is not unusual to have two to three weeks during the winter months without frontal passages.Fog is frequent in calm periods between November and February, forming in the early morning and generally dissipating during the afternoon.Statistically, the highest frequency of wind speeds greater than or equal to 27 kt occurs during the months of January and February. Wind speeds greater than or equal to 22 kt prevail during the maritime winter (October-March) and the predominant direction is south through west.
