July can be a strange month for the weather in Costa Rica. Though it is the Green Season, there is often a mini Dry Season, locally known as veranillo or little summer, from the beginning of the July and lasting through most of August. Temperatures are fairly constant with other months as elevation has more effect than seasonal patterns. Generally, it is a good idea to carry rain gear with you during the month of July, particularly in Caribbean areas. The Central Valley and Arenal has the usual comfortable upper 70s temperatures. The mornings are generally nice with showers developing in the late afternoons.

Local mosquito transmission of Zika has been reported in Costa Rica. The CDC recommends that travelers to Costa Rica protect themselves from mosquito bites. The mosquitoes that spread Zika usually do not live at elevations above 6,500 feet (2,000 meters) because of environmental conditions. Travelers whose itineraries are limited to areas above this elevation are at minimal risk of getting Zika from a mosquito.
