Climate & Best Time to Visit
The Great Blue Hole in Belize experiences a tropical climate, with warm temperatures throughout the year. However, the best time to visit is during the dry season (November to May) when the weather is sunny, the sea is calm, and visibility for diving and snorkeling is at its best. During these months, average temperatures range between 24°C to 30°C (75°F to 86°F), making it perfect for outdoor activities.
The rainy season (June to October) brings increased humidity, heavy rainfall, and the potential for hurricanes. The rough seas and unpredictable weather during this period can lead to tour cancellations and poor underwater visibility, making it less ideal for diving. If you plan to visit during this time, it’s essential to check weather forecasts and be prepared for possible delays or rescheduling.
For the best experience, plan your trip between December and April, when Belize has the most stable and pleasant weather conditions.
