Plan on getting wet from Cancun weather in October. It’s definitely part of the rainy season.

The annual Caribbean hurricane season hits Cancun especially hard in September and October.

They are the worst two months of the year for this Mexican coastal resort area that faces the Caribbean Sea.

Then again, the brave of heart might give it a try because prices are lower at that time of year. They might also get lucky with occasional clear skies.

The following numbers are based on a 30-year history and will vary year by year.

Average Rainfall

Cancun rainfall averages about nine inches in October, according to Servicio Meteorológico Nacional, Mexico’s government meteorology service. It is one of the highest amounts for any month and any destination in the Caribbean.

It is just slightly below the nine-plus inches that typically fall in September.

In contrast, less than two inches fall per month from February through April during the annual dry season.

The average number of days it rains during the month is 16, which actually is higher than September and any other month of the year.

Average Temperatures

The good news is that Cancun is still quite warm during this time of year.

The average high temperature in Cancun during October is about 88 degrees Fahrenheit or 31 Celsius, according to Servicio Meteorológico Nacional. The average low (mostly at night) is 75 Fahrenheit or 24 Celsius.

Seawater will feel comfortable for swimming and beaches will feel comfortable for sunbathing—when the sun is available.

Temperatures will get cooler as the month progresses.

Whether to Go

Cancun in October is an option for last-minute vacations in which the weather forecast looks clear in the days ahead.

It also is tempting because Cancun is more easily accessible than many other Caribbean destinations.

But it is not a good choice for anyone taking a long-term view of when to go. Cancun is much more attractive during the comfortable temperatures and low risk of rain during the spring.

Anyone who does think about going should consider travel insurance in case bad weather looks likely.
