Max Temperature

As expected, temperatures are generally highest close to the equator and decrease when further away. As the data in this sample was pulled in late September (shortly after the seasonal lag from the summer solstice caught up and temperatures began to decline,) the temperatures actually skewed higher toward the northern hemisphere, with peak temperatures at approximately 10 degrees north.

Note: Despite sampling of data from random coordinates, there still exists bias towards island and coastal cities. This is because greater than 70% of the Earth is covered in water, and attempting to pull samples from oceans would result in sampling the closest coastal city. This would be even more significant in the Southern Hemisphere where there is less landmass. Removing redundant cities helps somewhat, but the effects may be visible in the data.

• A few samples from 0 to 20 degrees south have an isolated trend of lower temperatures than other reported cities. These are likely a few non-coastal cities because coastal cities maintain more consistent temperatures during seasonal changes due to the insulation/heat-retention of water. Therefore, non-coastal cities in the southern hemisphere would have dropped to lower temperatures in the winter and and just begun warming up.
