Explanation

May well and might well add well after the modal to strengthen a guess: He may well be right means 'it is quite likely he is right'. It is stronger than a plain may (simple possibility) but still not a certainty. Might well works the same way and is only slightly more tentative. Use it when the evidence makes something clearly probable.

Examples

He may well be right about that.
It might well rain later, so take an umbrella.

Note

Don't mix up may well (= very likely) with may as well (= there's no better option, so let's do it): We may well win the prize is a prediction, while We may as well go home is a decision. See the next point for may as well.
