Latitude plays a crucial role in determining the intensity and distribution of solar energy received on Earth's surface. At lower latitudes near the equator, solar energy is more direct and intense due to the perpendicular angle of sunlight, resulting in higher temperatures and prolonged daylight hours during the summer months. Conversely, at higher latitudes closer to the poles, the angle of sunlight becomes more oblique, leading to less intense solar radiation and shorter daylight periods in summer. This variation significantly impacts local climates and ecosystems.

The intensity of solar energy at lower latitudes contributes to higher temperatures during summer. Areas near the equator experience more consistent and intense sunlight throughout the year, leading to warmer climates characterized by fewer temperature variations between seasons. This consistent solar heating also influences oceanic and atmospheric circulation patterns, which further shape regional climates and weather patterns.

In terms of harmful radiation, the angle of sunlight affects the amount of ultraviolet (UV) radiation reaching the Earth's surface. At higher latitudes, especially during summer when the angle of incidence is lower, the atmosphere absorbs more UV radiation. This absorption reduces the amount of harmful UVB radiation that reaches the ground, lowering the risk of UV-related health issues such as skin cancer. Conversely, regions near the equator experience higher UV radiation levels due to the more direct path of sunlight, increasing the risk of skin damage and skin cancer without proper protection.

Skin cancer rates are significantly influenced by latitude. Countries closer to the equator generally report higher incidences of skin cancer compared to those at higher latitudes. This correlation is primarily due to prolonged exposure to intense UV radiation, which damages skin cells and increases the likelihood of developing skin cancers such as melanoma. Public health initiatives in these regions often emphasize sun safety practices to mitigate the risks associated with excessive UV exposure.

High daily temperatures in summer are directly impacted by latitude and the angle of solar incidence. Near the equator, where sunlight is more direct, temperatures tend to be consistently high throughout the year. This results in hot and humid conditions, characteristic of tropical climates. In contrast, regions at higher latitudes experience more seasonal temperature variations. Summers are generally shorter and cooler due to the less direct sunlight, which results in milder temperatures compared to equatorial regions.

In conclusion, latitude influences solar energy distribution, UV radiation exposure, skin cancer rates, and daily temperatures in summer. Understanding these geographical factors is crucial for assessing climate patterns, health risks, and environmental conditions across different latitudinal zones. Efforts to manage and mitigate the effects of solar radiation on human health and environmental sustainability often take into account these variations in solar energy based on latitude.
