The Instituto Português do Mar e da Atmosfera (IPMA) has placed the South Coast and Mountainous Regions of Madeira under a yellow weather warning due to forecasts of occasionally heavy precipitation early Sunday morning, November 1, 2026. The warnings cover the period from midnight until 9 a.m. that day, accompanied by potential thunderstorms in the affected areas. The Serviço Regional de Protecção Civil is alerting the population to the worsening weather conditions in Madeira starting in the coming days, appealing for the reinforcement of preventive measures given the possibility of periods of heavy precipitation, recommending special attention during road travel and outdoor activities, particularly in areas most exposed to intense rainfall.
Weather Warnings and Forecast Details for Madeira
Meteorological alerts issued by the IPMA indicate that showers could reach high intensity during the early hours and morning of Sunday, November 1. JM Madeira reported that ahead of the weekend, precipitation would generally remain light, particularly on the northern slopes and highlands, before intensifying from Saturday, October 31, onward with a heavier impact on the southern slopes and elevated terrain. The weather will become unstable in the archipelago starting from the mid-afternoon of Saturday, October 31, with effects beginning to be felt especially from that afternoon onward.
SAPO noted that weekday forecasts for the region featured periods of cloudy skies and scattered showers driven by light southern winds under 20 km/h. An analysis cited by climatologist Alfredo Graca pointed to an isolated cold upper-level depression originating near the Azores, which could push accumulated rainfall past 40 mm in specific southern sectors such as Ponta do Sol, Câmara de Lobos, and Funchal. The weather system will feature frequent, sometimes heavy showers potentially accompanied by occasional thunderstorms, as well as a temporary drop in temperatures in some localities of the Madeirensian archipelago, particularly on Sunday, November 1, the All Saints’ Day holiday. Southern winds are expected to blow occasionally strong during these upcoming days, especially in the highlands of the archipelago.

Marine forecasts predict shifting wave heights across coastal zones
Marine forecasts from the IPMA outline shifting wave heights across coastal zones. JM Madeira reported that northern coastal areas and Porto Santo can expect north-northwest waves measuring between 1.5 and 2.5 meters. On the southern coast, waves will initially stay below 1 meter before climbing up to 2 meters by Monday, November 2.
Authorities recommend that residents keep drainage systems, gutters, and rainwater runoff paths clean whenever safe to do so; remove objects and materials that could hinder or obstruct water runoff; fix or collect exterior structures and objects that could be dragged away; and check the safety conditions of doors, windows, and shutters. On the road and outdoors, citizens are advised not to cross flooded roads, watercourses, or torrential zones; avoid circulating or parking in locations historically vulnerable to floods, landslides, and coastal overwash; redouble attention on mountain roads, hillside zones, and spots subject to falling rocks and trees; avoid remaining near the coastline during periods of greater marine agitation; and respect signage, closures, and all instructions from authorities.
