Forecasts for Cracow and nearby area:

Tuesday, July 26th

In southern Poland weather will be calm with small cloud cover. During the day locally cumuliforms would develop. Maximum temperatures will reach up to 28-31 Celsius degrees. Because of high temperatures it is recommended to have a headgear and bottled water mainly due to long remaining in the places of meeting. Showers and local thunderstorms could start to occur during midday and they may persist into the evening. Thunderstorms will be accompanied likely by excessive precipitation and small hail. During holy mass that will start the World Youth Day, thunderstorm will be also possible (5:00 PM). The development of storm cell exactly above Cracow has very small probability but it is still possible. Thunderstorms could also develop near Cracow before the holy mass, so cloud cover generated by the storm cell could decrease temperature, increasing thermal comfort of pilgrims thereby. Please remember that thunderstorm is local phenomenon.
