In Khasan, Russian Federation, awareness of the UV Index is crucial for safeguarding your skin health. With summers characterized by a Dwa climate, residents and visitors alike face heightened UV exposure, particularly during the midday hours when the index soars to 10—indicative of very high risk of harm from unprotected sun exposure. Understanding UV levels helps in preventing sunburn and reducing long-term skin damage, making it essential to stay informed about daily UV fluctuations. As you enjoy the beautiful outdoor surroundings, keep an eye on the UV Index to protect yourself from its potentially harmful effects.
The UV Index reveals a dynamic ascent and descent throughout the day, peaking with intensity during midday. Starting at a gentle 1 at 7:00 AM, it climbs steadily, reaching 10 by 1:00 PM and maintaining this highest level until 2:00 PM. This critical window indicates significant sun exposure, and it’s essential to take precautions. As the afternoon progresses, the index begins to taper off, dropping to 8 at 3:00 PM, then gradually falling to 1 by 7:00 PM. This data highlights the importance of being sun-smart during the peak hours to minimize UV exposure risks.

Throughout the year, the UV Index experiences significant fluctuations, indicating varying levels of sun exposure risk. From January (UV Index 2, low exposure) to February (UV Index 3, moderate exposure), there is a gradual increase in UV intensity. However, a sharp rise can be observed starting in April (UV Index 7, high exposure) peaking during the summer months of June and July (UV Index 10, very high), followed by an extreme level in August (UV Index 11, extreme). The high-risk months for sunburn are April through September, where burn times decrease to as little as 10 minutes in August. Residents and visitors are advised to take precautions during these months, including seeking shade, wearing protective clothing, and using sunscreen with a high SPF, especially during midday hours. As fall approaches, the UV Index drops again, providing some relief with moderate levels in October and November before returning to low levels in December.
