George Town Weather in September

September weather

September feels hot, sticky and often cloudy in George Town. The high reaches 30°C, and rain falls on many days, often in passing showers. That can interrupt beach time and boat trips, so keep your plans flexible.

Snorkelling at Eden Rock can still work between showers, while the Cayman Islands National Museum is a good rainy-day stop. Save long walks in the open sun for cooler breaks in the weather. With frequent rain and muggy air, September isn't the easiest month for a full day outdoors.

Events and crowds

There's no major island-wide festival or public holiday that reliably falls in September. It's also hurricane season, so storms can affect flights and boat outings, though that doesn't mean a storm is certain during your stay.

If you hate crowds, you'll find George Town quieter than in the winter high season. September is a low-season month, and accommodation can cost less than in the busier months. The trade-off is wetter weather and a greater chance that an excursion gets changed or cancelled.

Making the most of it

Plan a mix of indoor stops and short outdoor outings. Browse George Town's shops, visit the National Gallery, then head to Camana Bay for a meal when the rain eases. The usual beach day may be broken up by showers, but you can still enjoy a swim when conditions allow.

Travelling with kids? Keep the Cayman Islands National Museum in mind for a rainy spell.

One local tip: if rain catches you near George Town's waterfront, duck into the museum rather than trying to walk on to Seven Mile Beach in a downpour. It's close to the town centre, and gives you a useful way to wait out the weather.
