Asunción in May

April through September gives you the best weather - warm days, cool nights, less humidity. The rainy season from October to March brings oppressive heat and afternoon downpours that can flood streets. July and August are technically winter but feel like perfect spring weather elsewhere. Christmas and New Year see locals fleeing to beach towns, making the city quieter but also closing many restaurants. Independence celebrations in May bring parades and street parties worth timing your visit around. But here's the reality: Asunción works year-round if you can handle heat. Summer temperatures hit 100°F with crushing humidity, but everything costs less and you'll have attractions to yourself. Pack light, breathable clothes whatever season you choose. The weather changes fast, so layers help.
