一年中,1月平均气温最低,1℃;7、8月平均气温最高,28.7℃,夏季长达135天。

由于武汉处于北纬30度,夏季正午太阳高度可达83°,居于内陆、距海洋远,周围地形如盆地、集热容易散热难,河湖多、晚上水汽多,加上城市热岛效应和伏旱时副高控制,因而城区气温最高可以达到42℃,是中国三大火炉之一。

而硚口区属亚热带湿润季风气候,年降水量1150毫米──1450毫米,年日照总时数1810小时──2100小时,年平均气温16.3℃。

硚口区为武汉市七大主城区之一。

武汉市地形属于残丘性河冲积平原,地势北高南低,中部地平,沿长江、汉江展布平原。

平原南北两侧和蔡甸区中部为第四纪阶地,呈波状起伏的高岗和低丘,东北和北部为大别山余脉,地貌特征是低山丘陵,南部为丘陵岗地,全境土地大致为“二山三水五分田”。

在武汉市主城区内,长江及其最长支流汉水横贯市区,将武汉一分为三,形成了武昌、汉口、汉阳三镇隔江鼎立的格局。

硚口区地理坐标为北纬30°33“、东经114°19”,位于武汉市汉口西部,东接长江,与江汉区毗邻,地形平坦。

2、社会资源及发展前景硚口区地处武汉市商贸中心地区──汉口,南滨汉江,与汉阳区隔水相望;西抵舵落口、额头湾,北至张公堤与东西湖区接壤,东部是商贸旅游区,西部是武汉市新经济增长带,北接武汉市中央商务区,是武汉市重要的商业发展中心。
