Marcio Jose Sanchez / AP Photo: Google I / O has previously been held indoors.
Around 5000 participants are expected to flock to Google I / O, the Internet giant's developer conference which starts on Wednesday.
To cope with the nearly 30-degree heat in Mountain View, Google has put together a survival kit for the conference visitors.
It includes, for example, sunscreen, sunglasses, a water bottle and a headgear that can be worn as headband, hat and, for the slumbering, blindfolded.
One must assume that Google hopes that the sunglasses will be a bigger hit than the deferred project Google Glass, whose purpose was to develop a computer worn as a pair of glasses.
In addition, participants receive a copy of Google's own virtual reality glasses of cardboard and plastic.
