Tropical belts has the highest salinity due to high temperature(evaporation) and low precipitation than equatorial area. Maybe the temperature is high at equators but the evaporation creates precipitation which compensate or dilute the salt in the oceans. read more
On average, seawater has a salinity of 3.5% (or 35 parts per thousand). Water salinity often varies by location and season, particularly with hypersaline lakes in arid areas, so the salinity figures in the table below should be interpreted as an approximate indicator. read more
