The weather during Commencement weekend is unpredictable. We hope that it will be glorious and sunny, so you may want sunglasses and a water bottle for Ivy Exercises and for Commencement. Your parents and other guests may want sunglasses, a sun hat, and a water bottle. We will have water dispensers and paper cups at these events, but a water bottle might be more convenient.If the weather threatens rain, a raincoat and/or an umbrella would be in order. We will move Ivy Exercises or Commencement indoors only in the event of heavy rain.
