The best time to visit Niagara Falls is between June and August. During these peak summer months, the weather is warm and consistent, with average highs around 27°C, which makes the mist from the falls a refreshing experience rather than a cold one. This is also when all attractions, including the Maid of the Mist boat tour and the Journey Behind the Falls, are fully operational. While this period is the most crowded and expensive, it offers the "full" experience with long daylight hours—up to 15 hours in June—and nightly fireworks displays. For those seeking a balance of good weather and fewer crowds, September is an excellent alternative, offering comfortable temperatures and the beginning of beautiful autumn foliage. Conversely, winter visits (December–February) offer a stunning "frozen" landscape but result in many outdoor attractions being closed.
