I haven’t found a source for the real time water temperature on Watts Bar Lake near Spring City yet. If you have one please leave it in the comments below. In the mean time I put together this short blog article with some general guidelines on the water temp based on the seasons. At the end of each season you’ll see a footnote with tips on how to dress. While you might think when it is 70+ degrees you can go out with a T-shirt and you may be comfortable for a time but when you are moving on the water and the wind is blowing it will be cold especially if the water temp is in the 50’s. This is why it is best practice to dress for the water temperature. Hope this helps!

- Spring Dress -Since the tempeture varies wildly in the spring dressing in 2 or 3 layers is best with the outer layer being waterproof as it can rain out of nowhere during this time. ↩︎
- This is full summer apparel season. Whatever you are comfortable in goes here. One important thing to remember if you are going to be out on the water into the evening bring a sweatshirt to put on especially after dark. There is something about being out in the sun all day and then in the evening even if it is still 75 out you can get a chill.
↩︎ - A most wonderful time of year to be on the water but tricky to dress for. At times the water will be warmer than the air especially in late fall. So dressing in layers is in play here, just opposite of spring. More than likely you’ll start out light and add layers as the day moves on.
↩︎ - Think full winter apparel. Coat, toboggan hat, gloves and even a balaclava mast are advisable especially if you plan on going fast on the water. Typically we will get an extreme cold spell for a week or two in January and I would just stay off the water then. But in December I’ve seen it in the 70’s and the water temp is still in the upper 50’s and it’s just beautiful on the lake if you dress appropriately. ↩︎
