7.17.1 Climate

The cool winter season extends over November to February with mean daily maximum temperatures of 25 to 30° C and night temperatures of 10 to 15° C. The lowest recorded temperature being 4° C. Ground frost can occur inland. The hot summer season extends over May to September with maximum day temperatures between 40 to 45°C, the highest recorded being 48° C. Night temperatures are about 20 to 25° C. Therefore, it is important that during the hot season the temperature within the visiting tankers accommodation shall not exceed 25°C. Relative humidity is high throughout the year averaging between 50 to 60 per cent by day and 75 to 80 per cent by night. Heavy dew may be experienced throughout the year. Rainfall is usually associated with thunderstorms which are prevalent from November to May giving a total annual rainfall of 10 to 50 mm. Rain is rare during the remaining months while in some years there is none at all. Throughout the year the prevailing winds are from the West to North North East sector. They are strongest between November and April when they occasionally reach gale force. Gusts of up to 50 knots have been recorded (April) and a 24-hour mean wind speed of 32 knots from the North-West is on record (January). The shamal or strong North West wind may blow for periods of up to three days and raise a rough sea with waves up to 4.5 meters. Land and sea breeze is experienced throughout the year. Visibility is 10 nautical miles for 70 per cent of the time and less than 2 nautical miles up to 5 per cent on occasions due to dust, haze or radiation fog. Fog can occur during any month of the year but is most frequent in winter. Normally it develops during the night and early morning and clears by 10.00 hours. Usually the fog banks drift to seaward towards Sir Baniyas Island. Sea temperatures at 3 meters depth, range from 20°C (in winter), to 32° C (in summer). During the summer the 15 meters depth temperature is only a degree or so lower than that at the surface.

7.17.2 Wind and Tide

Prevailing winds are from the North West. However there are occasions, when sudden gusts of local ‘Shamal’ winds may be experienced where winds can go as high as 50kts. or higher. Rise of tide can be up to 2 meters but the usual variation is 1 meter. The highest average, spring high tide is about 2.0 meters above chart datum. The lowest average, neap high tide is 1.0 meter above chart datum.

7.17.3 Tidal Streams/ Currents

In the outer approaches to Ruwais, tidal streams would appear to attain a maximum of 1 knot while 1.7 knots may be encountered in the channel NE of Jazirat Sir Baniyas.

_Tidal currents in the area of the berths seldom exceed 0.4 knots. Tidal current is generally along a NNW - SSE axis.

_Tides are generally diurnal; winds from NE and NW may cause an increase up to 0.6 meters in the height of the tide. Max. Tidal rise is 1.2 m.
