Seasonal lag is the phenomenon whereby the date of maximum average air temperature at a geographical location on a planet is delayed until some time after the date of maximum insolation. This also applies to the minimum temperature being delayed until some time after the date of minimum insolation. A planet is generally considered to be a relatively large mass of accreted matter in orbit around a star that is not a star itself. ... Insolation is the incoming solar radiation that reaches a planet and its atmosphere. ...
Seasonal Lag on Earth
Earth's seasonal lag is largely caused by the presence of large amounts of water, which has a high latent heat of freezing and of condensation. Its length varies between different climates, with extremes ranging from as little as 15-20 days (for polar regions in summer) to as much as 2 1/2 months (for low-latitude ocean areas). Interestingly, in many locations, it is not "seasonally symmetric", that is, the time between the winter solstice and coldest time is not the same as between the summer solstice and hottest time. In low and middle latitudes, the summer lag is usually larger, while in polar areas the winter lag is larger. In mid-latitude continental climates, it is approximately 20-25 days in winter and 25-35 days in summer. Latent heat describes the amount of energy in the form of heat that is required for a material to undergo a change of phase (also known as change of state). Two latent heats are typically described. ...
Seasonal Lag on other planets
Other planets have different seasonal lags. Neptune, for instance, has a year that lasts 165 Earth years and a seasonal lag of about 30 Earth years.[1] The gas giants Jupiter, Saturn, Uranus and Neptune, as well as Saturn's moon Titan, all have substantial seasonal lags corresponding to the equivalent of between two to three months in Earth terms. Mars and Venus on the other hand have negligible seasonal lag of no more than a few days, and the same would be expected of Mercury since it has no atmosphere.
