Seasonal variation in surface temperature and salinity around Lagos harbour, Nigeria.
Continuous monitoring of Sea and Harbour (Lagoon) Surface temperature and salinity at two stations has been carried out from 1978 to 1981. This paper presents the findings for the period and relates it to the prevailing meteorological regimes. The pattern of sea surface temperature at Victoria beach in the study period shows a clearly defined mean maximum temperature of 29.34oC in April, and clearly defined mean minimum temperature of 25.63 in August. Depending on the year, there may be a less clearly defined mean maximum and minimum temperature in October/November and in January respectively. The pattern of surface temperature in the Harbour station is basically similar. The salinity cycle especially in the Harbour was found to be critically dependent on rainfall. Practical salinity values as low as zero was recorded in the Harbour during the rainy season while in the dry season, values greater than 30.0 were sometimes recorded. The effect of rainfall on sea surface salinity was expectedly less significant.
