1. Water needs a lot of energy to raise its temperature. This extra energy is needed to break hydrogen bonds. The temperature of water in oceans doesn't change with more than 1oC in one day: The temperature of other matters can change by 15oC in one day.
2. The boiling point of water is extremely high (100oC), while the hydrogen bonds are to be broken.
3. The freezing and melting point of water is high (0oC). Water becomes solid at a very high temperature, because the hydrogen bonds encourage the forming of a grating. A lot of energy is needed to break the combinations.
4. The weight of ice is less than the weight of water. That's why ice floats on water.
5. The thermal conductivity of water is high. Water can't be very warm at one point when another spot is cold. The warmth is always spread over all the water.
6. The needed energy to evaporate water is enormous. Again, the hydrogen bonds are taking a lot of energy to be broken.

the melting point for water is 33 degrees it can only melt from ice, otherwise the hottest it can get is boiling, solids melt

I don't think 33F is very high. Why does a gallon of water weight about 2 lbs more than a gallon of jet fuel.
