I would like to reiterate from the first email as well as what Tom had stated that a lot of ventilation would be your best friend in your situation. The more the better. Your main concern should be simply keeping the rain off of the Electronics but use a lot of ventilation. Solar powered fans may help. Your enclosure should stay as close to ambient temperature as possible. That is the ideal of what you would be able to hope for when it's sunny and hot.
