Central Oklahoma in December

April through June gives you wildflower season without the brutal summer heat. October's perfect - crisp mornings, warm afternoons, and the State Fair if you're into funnel cakes and livestock competitions. Avoid July and August unless you enjoy feeling like you're inside a hair dryer. Winter's mild but unpredictable - you might get 70-degree days or ice storms that shut down the city. Spring brings tornado season, which sounds scarier than it is. Most storms pass through quickly, and locals treat severe weather like dinner theater. The National Weather Service in Norman is the best in the country, so you'll have plenty of warning. Summer festivals like the Red Earth Native American Cultural Festival happen during the hot months, but indoor venues keep you comfortable.
