While those living on the streets have to bear low, life-threatening temperatures in winter months, the summer is not without its challenges.
"Some of the less apparent concerns that our clients face would be things like access to water, sunscreen and places where they can go and get in the shade, and out of the sun," said Megan Baillie, acting executive director for Keys: Housing and Health Solutions.
Baillie said heat stroke and heat exhaustion are a concern during scorching summers and this year is expected to be a hot one.
"We always work with street nurses, for example, and our outreach teams will pack backpacks filled with sunscreen and bottles of water and take it out on the street and try to reach out to people who might not be interested in coming into the shelter."
