Weather models are currently indicating a significant influx of hot air over the Iberian Peninsula, bringing the potential for several consecutive days of intense heat, particularly in inland regions.

According to meteorological forecasts, the warm spell is expected to strengthen from the start of the week, with temperatures rising steadily through Monday before peaking around Tuesday and Wednesday.

Some of the highest temperatures are forecast for inland areas, including the Douro Valley, Beira Baixa, Ribatejo and Alentejo. In the hottest locations, thermometers could reach 42°C to 44°C if current projections are confirmed.

Coastal areas are expected to remain somewhat cooler due to the influence of Atlantic air, although temperatures along parts of the coast may still rise above normal for June.

Forecasters say the heat is being driven by a weather pattern that is allowing very warm air to move northwards across the Iberian Peninsula. While details may still change over the coming days, the overall trend points towards a prolonged period of above-average temperatures.

The heat is not only expected during the day. Night-time temperatures could remain unusually high in several regions, particularly across the interior, making conditions uncomfortable and reducing opportunities for overnight cooling.

Meteorologists also note that the combination of intense heat and atmospheric instability could trigger isolated showers or thunderstorms in parts of northern and central inland Portugal during the afternoons.

Current forecasts suggest temperatures may begin to ease towards the end of next week, although confidence remains lower at that range.

Health authorities typically advise people to take extra precautions during periods of extreme heat, including staying hydrated, avoiding strenuous activity during the hottest part of the day and checking on elderly relatives, young children and other vulnerable individuals.

If forecasts hold, the coming week could bring some of the highest temperatures recorded in Portugal so far this summer, with inland regions expected to experience the most challenging conditions.
