How the forecast was made

IMGW-PIB released a map based on the ECMWF long-range model. Moreover, the map shows weekly averages of daily maximum temperatures. Therefore meteorologists compare four weekly maps for July. The first full week, July 6-12, will feel noticeably cooler. In addition, coastal cities like Gdańsk should see highs near 20°C. Central Poland will enjoy 23-24°C. However that respite will end quickly.

When the Warsaw heatwave will hit: 13-19 July

The model predicts a strong warm air mass from the Mediterranean or North Africa. Consequently, much of Poland will see a sustained heat spell between July 13 and 19. In Lower Silesia and Greater Poland, weekly mean daily highs may reach 30-31°C. In central Poland, cities such as Łódź and Warsaw should average about 30°C. The east will be slightly cooler, near 29°C. Importantly, these numbers represent an average of seven days. Therefore this is a week-long pattern, not a one-day spike.

What follows later in July

After the peak, temperatures should fall moderately. From July 20 to 31, expect highs around 25-28°C. However the month will stay warmer than average. Consequently people with heat sensitivity should remain cautious. Meteorological predictions will likely change. In addition, ECMWF updates daily, which improves accuracy near the date.

💡 GOOD TO KNOW: If you live in Warsaw, plan outdoor events carefully. Public services like NFZ (the national health fund) provide emergency care, and local clinics can fill prescriptions. Heat can cause dehydration and heat exhaustion, especially for older adults and children. Keep ID documents like PESEL numbers or passports handy in case you need urgent care. Moreover, public cooling centers and shaded parks often help during heat waves. Lastly, employers must consider worker safety during heat; contact local authorities for guidance.

Why this matters to newcomers. First, heat affects daily life and logistics. For example, public transport can suffer delays. In addition, construction or manual work may require schedule changes. Second, health systems such as NFZ can see higher demand. Therefore register with a GP early. Third, a prolonged hot spell raises electricity use. Consequently buildings without air conditioning may heat up fast. For long trips, book accommodation with cooling options.

Practical tips for the week of July 13-19. Start planning now. Buy sun blinds or a fan. Drink water often and avoid intense exercise midday. Moreover, move strenuous chores to morning or evening. Check forecasts daily as the date approaches. Finally, keep flexible plans for outdoor events and be ready to shift them to cooler days.
