D\u00e9j\u00e0 ce lundi les temp\u00e9ratures au sud de Paris atteindront 30 \u00e0 35 degr\u00e9s. Port\u00e9e par un vent de sud, cette masse d&rsquo;air n&rsquo;aura donc que peu de mal \u00e0 atteindre notre pays.<\/p>\n<p>Mardi vers 15 heures. les temp\u00e9ratures monteront jusqu&rsquo;\u00e0 25 \u00e0 29 degr\u00e9s dans la majeure partie de la Belgique. Ce n&rsquo;est qu&rsquo;en Flandre occidentale et dans les r\u00e9gions c\u00f4ti\u00e8res qu&rsquo;il fait nettement plus frais, entre 20 et 24 degr\u00e9s.<\/p>\n<p>Cependant, une telle chaleur n\u2019a rien d\u2019inhabituel \u00e0 cette p\u00e9riode de l\u2019ann\u00e9e.
