San Carlos Mexico WEATHER

The weather in Guaymas-San Carlos is hard to beat. With summer daytime highs in the 90’s and winter evening lows in the 50’s, there’s never a reason to stay indoors! Due to its location in the arid region of northwest Mexico, you won’t find the rainy seasons or the high humidity associated with the more tropical locations. As a result of this, you’ll find very few mosquitoes or pesky "no-see-ums" that inhabit the tropics. Finally if you are worried about hurricanes … they are not a major concern in San Carlos as they are in Cabo, La Paz or on the Caribbean side of Mexico. While we have seen major tropical depressions (and a destructive storm surge that hit Costa del Mar and Club Med several years ago) there are NO official recordings of even a Category 1 Hurricane (sustained winds between 74-95 mph) in San Carlos. Because of this, many sailboats are brought from La Paz and Mazatlan every hurricane season to avoid any potential storms in those areas.

Here a chart that will help separate fact from fiction concerning hurricanes.

Categories of Hurricanes

Cat.	Damage	Winds	Storm Surge
1	Minimal - Might blow over your tool shed and damage a few plants. Lowest roads flood.	74-95 mph	4-5 ft.
2	Moderate - Some building damage and a lot of plants and trees down. Mobile homes don't fare very well, either. Low-lying evacuation routes will be flooded 2-4 hours before the center of the storm arrives. This is when you start wondering if you secured your boat well enough.	96-110 mph	6-8 ft.
3	Extensive - Kiss your mobile home goodbye. Some structural damage to buildings. Flooding on the coast and anything less than 5 foot above sea level as far as 8 miles inland.	111-130 mph	9-12 ft.
4	Extreme - Your mobile home is in Tampa now, and roofs are blowing off houses. Lots of damage to lower levels of buildings on the beach, and inland terrain lower than 10 foot above sea level will flood.	131-155 mph	13-18 ft.
5	Catastrophic - You did evacuate didn't you? If not, this is when you kiss your butt goodbye. Roofs are blowing off left and right, and some buildings are just blown completely away (not even counting mobiles - they were gone long ago). Beachside buildings are going to be a huge mess on all the lower floors that they have. If you rode out the storm inland you better be on a ridge at least 15 foot above sea level, or you're going to be flooded.	156 mph...	18 ft. +
