If you have a proxy running today then usage statistics will tell you
this information.

This very basic usage statistics can either be collected by running
statistics on your access.log, or by looking into cachemgr. When
using cachemgr make sure to read the values at peak load time, not
after hours when the proxy is barely used..

For runtime monitoring I recommend plotting requests/s and other basic
performance metrics using MRTG or RRDTOOL. This gives very nice
graphs showing how the traffic load varies over the day, updated in
near real time. This type of information is easily queried by such
tools via the SNMP interface of Squid.
