WebThe temperature of a plant's foliage may be higher than the outside temperature if the plant does not have enough moisture to evaporate and cool off the leaves. Relative humidity measures the saturation level of air with water; hence a relative humidity of 100% implies that the air cannot take any more moisture. If the humidity levels would be 80%, it will feel like 157F (thats why Florida is close to hell temperatures in the summer). If you cool it down to below 78.8F, the relative humidity level goes to 100% and the water condenses (The dew point).
