Lets assume you live in an area where you get 16 hours of daylight, and 8 hours of night on the longest day of the year. This results in 8 more hours of daylight. During the dark of night you are loosing heat to space, and during midday you are adding heat from the sun. The hour before and after sunrise and sunset are fairly neutral in adding or loosing heat. As a result there is about 6 hours of extra heating on the longest day. Additional daily heating continues for most of the remainder of summer, even though the amount of daylight gets shorter each day. A month after the longest day, you might still be getting 2-3 extra hours of heating per day. If you add more heat each day, the temperature will rise. This explains why the hottest days of summer are usually about 6-7 weeks after the longest day. The neutral heat gain/loss an hour before and after sunrise and sunset help explain why the hottest day isn't the last day of summer. A reversal of the "daily heat budget" results in the coldest days of winter occurring 6-7 weeks after the shortest day.

So it takes a couple of months for everything to warm up annd melt all the snow.So thats why it takes a month or two for the hottest weather.
