The first sentence is best filled in with "climate" - it's the most general characteristics of how warm it is in Hawaii, not only today.
In the second sentence, the situation is the opposite- it's only about the situation on that given day, so the answer should be "weather"
And about climate:
is predictable (it depends on the longitude for example)
it occurs over a long period (this is true!)
has a global impact (for example the climate change in the Amazon region also influences climate in other parts)
