Methanol is simply more acidic than waterjust because its pKa value is less than that of water. And the less numerical pKa value a compound has, more acidic the compound is. pKa value of water and methanol are 15.7 and 15.5 respectively. Not much difference , still this much only makes the Methanol to be called more acidic. The lower magnitude of pKa of Methanol accounts for its more acidity.

Methanol is slightly more acidic than water Explanation:- A compound would more readily release a proton or H+ if upon release it gets more stabilized than what it was earlier. Waterupon release of H+ would result into hydroxide ion, OH- , whereas Methanolreleasing a proton would give Methoxide ion , CH3O-. Now checking for the stability of the resulting anions in both the cases. In OH- the electron density over the negatively charged Oxygen increases , since Hydrogen is more electropositive than Oxygen and thus has a tendency to increase the electron density over Oxygen , this being resulting to be comparatively destabilizing of the resulting anion. While that in Methoxide , the carbonbeing attached to the Oxygen is comparatively less electropositive than Hydrogen , thus decreases the electron density over oxygen atom quite a little
