Final answer:
The hottest day of the given month reached 95 degrees, while generally, July and August are the hottest months due to the ocean's slow heating response.
Step-by-step explanation:
The hottest days of a month are determined by analyzing daily high temperatures. Referring to a given data set, which lists daily high temperatures, we can identify the hottest day by selecting the highest temperature recorded. In the data provided, the hottest day of the month reached 95 degrees. Based on the bar chart and time of year, the warmest days generally fall in July and August, rather than on June 21, which is the summer solstice. This delay is due to the ocean's slow response to changes in solar heating. As a large thermal reservoir, water takes time to heat up and cool down, causing the peak heat to occur weeks after the days with the most sunlight.
