Hi there!
Most of the ocean has salinity of about 34-36 ppt (parts per thousand, as in 34-36 ppt salt out of 1000 g water). There are areas of the world where there are high winds and low rainfall or river inflow around salty bodies of water, such as the North and South Atlantic, and the Mediterranean Sea.
Another area where there the water can be extra salty could be in Antarctica, right at the ice, even though much of the waters around Antarctica are of the typical salinity of 35 ppt. It's harder for salt water to freeze due to the salt, but when sea water freezes, the ice rejects the salt (due to easier energy and heat flow). That salt of course remains in the liquid water nearby while the water freezes and could greatly increase the salinity in that brine.
Hope this helps! You can look up this information further online. Please let me know if you have any further questions.
