Summer is the sweet spot here — highs peak around 83° in mid-July, making it prime time for Lake Erie and Cedar Point. By mid-January, average highs barely crack 32°, so winter visits require serious cold-weather commitment. The wettest stretch runs late June through early July, averaging about an inch of precipitation per week, so pack a rain layer even at the height of summer.
