WarmWeather in Prague in July
July is a good time for Prague if you want warm city weather and can keep your plans flexible around rain. Average daytime highs are about 25°C, with nights around 15°C, so light clothing usually makes sense but an evening layer earns its place. The catch is about 12 rainy days: this is not a reliably dry summer break. Go for comfortable warmth rather than a guarantee of clear skies.

Warm enough for summer clothes, with occasional hotter days
July suits travellers who enjoy warm days without wanting intense heat throughout their trip. The average high is comfortable for spending time outdoors, but it does not rule out a sweaty afternoon: 10% of days reach 30°C. On hotter days, put more active plans in the morning and leave room for a shaded or indoor break at midday. Evenings need a different approach. The average night low makes a light jumper useful, and the coldest nights can fall to around 12°C or below. Pack mostly light clothes, but do not rely on shorts and T-shirts for every part of the day.
Rain is the main compromise
The reason to hesitate over July is rain rather than cold. About 12 days have measurable rainfall, so a waterproof layer and shoes you are comfortable wearing in the wet are sensible packing choices. That does not mean those days are wet from morning to night, but it does mean a fully outdoor schedule leaves little room to adapt. Keep indoor options available and use dry spells for longer walks. July works well if you can change the order of your plans; it is less suitable if your enjoyment depends on consistently dry weather. Warm conditions alone are not a reason to leave rainwear at home.
