The weather is beautiful in the Grand Circle region and the water at Lake Powell is surprisingly warm for most of the season. It can get pretty hot in July and August compared to the milder months of May, June or September. Springtime (March, April & May) can sometimes be windy and the water is still chilly (you may need a wetsuit for skiing). Spring weather is unpredictable and a cold snap in March is not uncommon. September is an ideal month for travel to Lake Powell for many adventures as the air temperature has cooled off a bit, yet the water is still extremely warm and the crowds have dispersed somewhat. It rains more in September. Early October is still surprisingly a great time to visit Lake Powell as long as the weather holds. The lake is relatively empty of visitors and the water is usually still warm enough for skiing or swimming — even into the third week of the month. However, is seems as if more and more visitors have discovered that traveling during the “shoulder seasons” is a wonderful time to visit.
