Rain, rain, and more rain. The wet stuff epitomizes Athens' weather, and not just in the spring. It rains in Athens year round, but thankfully, it's really only constant in the springtime. Students agree that you should never leave home without an umbrella because the rainstorms can be completely random and without warning, not to mention torrential. Some students even go as far as to say, you should own a fleet of umbrellas, just so wherever you are, there's one handy. That may be a bit overboard, but as stated above: it rains. It rains and it rains and it rains. But, other than showers, the weather is pleasant and typical to Ohio.
If you don't like rain, then maybe OU isn't the best choice. But, the rest of the weather is decent and predictable for the season. The rain does, after all, help the gorgeous flowers that pop up all over campus in spring. Just make sure to bring an umbrella, rain coat (OU rain pullovers are available at bookstores), and make sure to layer clothes; it may be cold outside, but it can be assured that the heat is blasting in the classroom buildings. Stay on your toes as Mother Nature throws a few curves your way.
