electron releasing groups decrease acidic strength of phenol whereas electron withdrawing groups increase its acidic strength.
methyl is a electron releasing with both +I effect and hyperconjugation.
At para position it has both +I and hyperconjugation but farther distance from OH .
at both ortho and meta position it shows only +I effect but since ortho is closer position to OH group hence higher +I than meta and hence least acidic.the order of acidity is
meta methyl phenol>para methyl phenol>ortho methyl phenol
