Is September a good month to go to Cancun?
From a weather forecast perspective, September is a fantastic month to visit Cancun, despite the fact it is still in the rainy season.

Alongside October, September is the month when a hurricane is most likely.
The oceans to the east and south of the resort are where hurricanes form. And since these areas will be at their hottest, their formation is more likely.
But even though September falls in the middle of the hurricane season, the chances of Cancun being affected by a hurricane are still remarkably low. In fact, only two hurricanes have hit Cancun in the last 30 years.
Daily averages stay pretty constant at 28°C (82F) throughout the month, with a few fluctuations up to 29°C (84F) at the start. Temperatures may drop to around 27°C (80F) by the end of the month.

Beaches for September for Cancun
Playa Caracol is known as the last "real beach" in the north of the resort along the Hotel Zone, found in between Plaza Caracol and Xcaret Dock.

Onsite services and amenities include lifeguards, bars, restaurants, sun loungers and parasols.
For another quiet beach, try Playa Langosta. Also set within the north of the Cancun Hotel Zone, this beach is made up of fine golden-white sand and gentle turquoise waters which are roped off so swimmers can't go too far and get swept out to sea.

Although there are no toilets provided on the beach, there is a snack bar which sells traditional Mexican food and cool drinks, plus locals regularly walk along the beach selling fruit and homemade sandwiches.
