Cabo San Lucas is one of the most arid cruise ports on the Mexican Riviera. But there are still best and worst times to visit this popular vacation destination on the west coast of Mexico.

The best time to visit Cabo san Lucas is April through June. The worst times are August and September. But some months are better than others.

Cabo San Lucas is one of the driest cruise ports on the Atlantic and Pacific coasts of North America.

Cabo lies at the southern tip of the Baja California peninsula. It attracts numerous tourists throughout the year because of fishing, golf, quality resorts and of course the warm Mexican Riviera weather.

What makes it a little unusual is that it rarely feels the impact of the annual Pacific hurricane season that often sends drenching rains to places along the western Mexico coast. Still, it’s not always dry.

Best Months to Visit

Cabo San Lucas has distinct wet and dry seasons, and the dry season is pretty close to bone dry. The city averages only about one inch of rain per month or less for 10 months out of the year.

The driest period starts in February and goes through July. February has averaged less than one inch over a 30-year history, according to Mexico’s government meteorology service (Comision Nacional Del Agua). March through June are even more dry and average less than 0.1 inches of rain per month—barely any rain at all.

But Cabo San Lucas temperatures vary quite a bit throughout the year. The best months to visit also depend on how much time visitors want to spend at the beaches or in the water.

The average daytime temperature in January and February is in the upper 70s Fahrenheit. This is the worst time to visit for beach lovers. The average high eventually climbs into the upper 80s Fahrenheit in May and June and finally breaks through 90 in July.

Nights are quite cool for most of the dry season with the average lows in the 50s Fahrenheit from January through April.

That makes the ocean too cool for swimming in the early part of the dry season for people who like to spend time on the beach.

Anyone who wants the warmest temperatures and doesn’t mind a little more rain might plan on a vacation there in July. The average high is 92 degrees Fahrenheit, and the average rainfall is still less than one inch.

Another good option is June. It has little rain and warm daytime temperatures. The only downside is the nighttime temperatures, which again will make the seawater chilly at times, especially in the mornings.

A bad month for weather in Cabos San Lucas is an average month for many Caribbean islands.

The rainy season is brief and light. August averages about 2.5 inches of rain and September exceeds more than three inches. September is the peak month of storm and hurricane activity each year for the Pacific and Atlantic coasts.

But it rains on average only three days each month, which is well below the normal levels for many destinations. Based on the total rainfall, any day that it rains will produce a lot of rain.

Temperatures remain quite warm with the average highs at 90 degrees Fahrenheit or above in August through October. During our last 10-day visit to Cabo in October, temperatures reached into the 90s every day, and it never rained once.

Like the dry season, November and December usually experience less than one inch of rain each month, but high temperatures start dropping into the 70s Fahrenheit. These months are good for land activities but less appealing for water activities.
