There is no way to accurately predict when Bermuda will come to life each spring, but in very general terms, the Bermuda will likely be greening up by mid-April, though still fairly thin. It varies; 2024 was pretty early, 2023 much later. Conventional wisdom is that overseeding slows up the Bermuda at least somewhat.
But as Hart said, I don’t think I’d let any of this keep me from that trip.
