At 15° Celsius the specific gravity values for fully charge battery = 1.290.
The Half charge = 1.200.
And Fully discharge = 1.110.

So, the Specific gravity at any particular "t" temperature is given by;

S( at t ) = S( at 15 ) - (0.018/25)*(t-15).

It's clear that on increasing temperature specific gravity decreases.
