How long does it take to process a Tourist ME visa application for Thailand?

If you got your METV issued today it would be valid to the beginning of April so a 60 day re-entry then would take you to the end of May and there would also be a 30 day extension available

I applied for a METV back in August, I honestly submitted on a Friday and got it Tuesday. Couldn't believe it. I was in the UK

You're asking a question that no one can answer 🙁 the processing time varies by consulate.

Also it is controlled by how well you are at filling out and uploading the required documentation.

IF they have to ask for additional documentation it slows the processing time, if you get everything uploaded correctly when you apply it goes faster

I'd say depending on the consulate start the application a minimum of 4 weeks before you're planning to make your trip

BUT

take into consideration any holidays (when they don't process visa applications) and also check the posted processing time on the website of the thai consulate you're applying for the eVisa thru.
