Grand Cayman weather in April is hotter and drier than most other months of the year.

Grand Cayman, the largest island in the Cayman Islands chain, is hot in more ways than one. It is one of the busiest ports for western Caribbean cruises.

Major attractions such as Seven Mile Beach and Stingray City make the island especially popular with active vacationers.

The Caribbean Tourism Organization says that March is much more popular for Grand Cayman visitors than April. Many schools have spring break during that March, but April offers warmer temperatures and fewer days with rain.

Temperatures in April

The average high temperature for Grand Cayman in April is 89 degrees Fahrenheit or about 32 Celsius, according to historical data from the National Meteorological Service of the Cayman Islands.

The average low temperature is 71 Fahrenheit or about 22 Celsius. The average lows occur mostly at night.

Seawater temperatures usually average about midway between the highs and lows of the air temperatures. A water temperature of about 80 Fahrenheit or 27 Celsius is usually comfortable for swimming. Mornings will have the coolest water temperatures and mid afternoon the warmest.

Because of hot daytime temperatures, visitors may find that land activities are best in the mornings and water activities best in the afternoons.

Rainfall in April

The Cayman Islands have the lowest amount of rain historically in March for the entire year. April is the second lowest with an average of less than two inches.

But April has an average of seven days with rain while March has an average of 10. So it rains less often in April than March.

Anyone planning a cruise or overnight vacation to Grand Cayman should know that April is the end of the dry season for the island.

Rainfall jumps to nearly six inches in May and stays at that level until August. It starts to climb again until reaching a high point for the year of more than eight inches in October.

Whether to Go in April

April weather for the Cayman islands is ideal for visitors who like hot temperatures and comfortable seawater. It also is a great month for low rainfall and smaller crowds.

March weather is less hot during the day, but it also is quite a bit cooler at night. Seawater temperatures may feel chilly at times for swimming for part of the day.

April also is better than May or later months that have a higher risk of rain.
