The increase in the ocean's average water temperature during mid months of the year may be associated with the summer season and therefore those cities should be located in the northern hemisphere.
<h3>Why does temperature vary in the Hemispheres?</h3>
Temperature varies in the Hemispheres due to the amount of solar radiation received by the earth's surface, which is higher during mid-months (i.e. June, July and August) in the northern hemisphere.
Therefore, with this data, we can see that temperature varies in the hemispheres according to the month which is associated with the solar radiation received in these months.
