Welcome to the Mazatlan Forum. One Question that is asked many times is "Whats the weather right now" Or " Whats the weather like in July etc"
Well, here are a few resources for you.
For the weather station at the Airport wunderground.com/global/stations/76458.html
This site has the current forecast, and a historical search option. You can click on "trip Planner" enter your dates and see what the "average" weather is for that time.
Of course, just like at home, nobody can predict what the weather will be next month, let alone next year...but it will give you a pretty good indication of what generally happens at that time of year.
Note that there is a drop down menu for selecting a source for your current weather information. This option changes as the volunteers running the various weather stations have technical trouble or move etc. The Airport is always available, but sometimes there are stations to the north of the Golden Zone, sometimes there are also stations in Centro. Fun to see the temp differences in the various areas.
And a favorite resource is of course the Beach Cam!!
