During the summer of 2007 several Greek regions suffered periods of extreme heat, with midday temperatures of over 40 degrees C on several consecutive days. High temperatures were also recorded on the east coast of central Greece, where a complex sea breeze circulation system frequently develops. The more intense events occurred at the end of June and July. The highest temperatures were observed on 26 June and 25 July, while the sea breeze developed only on 25 July. Meteorological data collected at two sites-a coastal urban location and an inland suburban site that is not reached by the sea breeze flow-as well as pollution data collected at the urban site, were analysed in order to investigate the relationship between sea breeze development and the prevailing environmental conditions during these two heat wave events. The analysis revealed that sea breeze development affects temperature and pollution levels at the shoreline significantly, causing a decrease of approximately 4 degrees C from the maximum temperature value and an increase of approximately 30% in peak PM10 levels. Additionally, several stress indices were calculated in order to assess heat comfort conditions at the two sites. It was found that nocturnal comfort levels are determined mainly by the urban heat island effect, the intensity of which reaches up to 8 degrees C, while the applied indices do not demonstrate any significant daytime thermal stress relief due to sea breeze development.
2007 年夏天，几个希腊地区经历了一段时间的极端高温，连续几天中午气温超过 40 摄氏度。希腊中部东海岸也记录到了高温，那里经常出现复杂的海风环流系统。更强烈的事件发生在 6 月底和 7 月初。最高气温出现在 6 月 26 日和 7 月 25 日，而海风仅在 7 月 25 日发展。为了研究这两次热浪期间海风发展与盛行环境条件之间的关系，对两个地点（沿海城市位置和内陆郊区位置，海风不会到达该位置）收集的气象数据以及城市位置收集的污染数据进行了分析。分析表明，海风发展对海岸线的温度和污染水平有显著影响，导致最高温度值降低约 4 摄氏度，峰值 PM10 水平增加约 30%。此外，还计算了几个应激指数，以评估两个地点的热舒适条件。结果发现，夜间舒适水平主要取决于城市热岛效应，其强度可达 8 摄氏度，而由于海风发展，应用的指数并没有显示出任何显著的日间热应激缓解。
