Manzanillo Average Weather - Best and Worst Months to Visit

Surfer
Manzanillo’s average weather ranges from extreme dry to extreme wet. No doubt most visitors will want the dry season.

This cruise port on the Mexican Riviera is located about 170 miles south of another popular cruise port at Puerto Vallarta in the state of Jalisco.

The city is known for its beaches, fishing and historical sites. It also overlooks two bays -- Manzanillo and Santiago.

Its location means temperatures will be warmer, but more importantly it feels the impact of the Pacific hurricane season, which runs from mid May to the end of June.

The Manzanillo hurricane season shows the same pattern as most other cruise ports in the Mexican Riviera.

Even though the season officially begins in the middle of May, few major storms or hurricanes start to appear until later in the year.

Manzanillo has about five inches of rain and nine rain days on average in June, according to historical data from the Mexico National Water Commission.

Storm and hurricane activity picks up starting in July. Total rainfall increases to nearly six inches, but then it jumps to more than eight inches in August and more than 10 in September.

Rain days increase to 14 in July, 15 in August and 16 in September, the commission reports.

Like June, October is a transition month between the wet and dry seasons.

Dry Season


Manzanillo’s dry season is nearly bone dry for a large part of winter and spring.

Average rainfall is one inch or less per month from November through May. Some months have almost no rain at all.

The average number of rain days declines to less than two from November through January and less than one from February through May.

Manzanillo Temperatures


Temperatures are warm and moderate throughout most of the year and stay within a small range each month.

The coolest months of the year are January through April with an average high of about 85 degrees Fahrenheit or 29 Celsius, according to the commission.

The average lows during those months reach the upper 60s Fahrenheit and upper 20s Fahrenheit. Water temperatures will be cool in the mornings.

The warmest months of the year are July and August with an average high of about 90 degrees Fahrenheit or 32 Celsius.

Average lows during the summer increase to the mid 70s Fahrenheit or mid 20s Celsius. Water temperatures may be balmy at times.

Best Times to Go


Mexican Riviera weather has a clear pattern of wet and dry seasons for cruise ports such as Manzanillo.

For people who like beaches and swimming, the best months to visit Manzanillo are May and November because of the combination of low rainfall and warm temperatures.

For everyone else, the best months are November through May.

Anyone planning a vacation during other times of the year should avoid Manzanillo in August and September because of the high risk of rain.

June, July and October have a moderate risk of rain and are worth a look for last-minute vacations. In those cases, it is wise to check the seven- or 10-day weather forecast before making a decision.
