It may be such that when you want to increase the heat content of water externally by changing the temperature,as specific heat capacity of water is high it will require more amount of heat in comparison to any other substance of same mass and same change in temperature.
Suppose heat required is #H1# for increasing the temperature of water by #x# degrees of mass #m# and it's #H2# for an other object of same mass and change in temperature.
So,we can write,
#H1#=#m*Swater*x#...1
#H2#=#m*Sobject*x#...2

So, #((H1)/(H2))#=#(#Swater#/#Sobject#)#...#(1÷2)#

As, S water>S object

#H1>H2#
So,you can have the idea that water gets heated the last than any other substance and you can explain from this why the sand of beach gets heated earlier than sea water.
