A good exchange rate for pounds to dollars, meaning using pounds to buy dollars, is when the pound is strongest against the dollar. The stronger the pound is to the dollar, the more dollars you will get for your pounds. As of Oct. 8, 2021, 1 pound will buy 1.36 dollars. If the pound strengthened in a few months, and 1 pound bought you 1.5 dollars, this would be a better exchange rate.
