Considerations

Unpredictable spring weather means you'll experience four seasons in one day - pack layers as morning chill gives way to afternoon heat and evening coolness
September rains arrive without warning and last 45-60 minutes, turning unpaved streets in Mercado Cuatro area temporarily muddy
Strong spring winds (up to 40 km/h or 25 mph) make riverside walks along Costanera challenging and outdoor dining uncomfortable on some days

Best Activities in September

Paraguay River Boat Tours

September's mild temperatures make river cruises perfect as morning mist lifts off the Paraguay River around 9am, revealing wetland wildlife awakening from winter. Water levels are optimal after winter rains, and you'll spot capybaras, caimans, and over 200 bird species without summer's oppressive heat. Afternoon tours benefit from spring's golden light hitting the water.

Booking Tip: Book 7-10 days ahead through established river operators. Tours typically cost 150,000-250,000 PYG (roughly $20-35). Morning departures (8am-11am) offer best wildlife viewing and cooler temperatures. Look for boats with shade covers as September UV is intense.

Historic Center Walking Tours

September mornings are perfect for exploring Casco Histórico when temperatures hover around 16°C (61°F). The spring light beautifully illuminates colonial facades along Palma and Chile streets. You can comfortably walk 3-4 km (1.9-2.5 miles) through cobblestone streets before midday heat arrives. Evening tours work well too as temperatures drop after 6pm.

Booking Tip: Self-guided walks work best in September's pleasant weather. Organized tours typically cost 80,000-120,000 PYG ($11-16) for 3-hour walks. Start early (8am) or late afternoon (4pm) to avoid midday heat. Download offline maps as some historic areas have poor cell coverage.

Ñandutí Lace Workshop Experiences

September's indoor cultural activities become appealing during unpredictable weather days. Traditional Paraguayan lace-making workshops in Itauguá (28 km or 17 miles from Asuncion) offer authentic cultural immersion. Spring is when artisans begin preparing pieces for summer festivals, so you'll see master craftswomen at peak creativity.

Booking Tip: Day trips to Itauguá workshops cost 200,000-300,000 PYG ($27-40) including transport and materials. Book through cultural centers in Asuncion 5-7 days ahead. Most workshops run 9am-3pm with traditional lunch included. Bring cash as most artisan cooperatives don't accept cards.

Cerro Lambaré Nature Hikes

September's moderate temperatures make the 2.5 km (1.6 mile) hike up Cerro Lambaré comfortable, offering panoramic city views. Spring wildflowers bloom along trails, and clear September skies provide excellent photography conditions. The summit at 156 m (512 ft) gives spectacular sunset views over the Paraguay River without summer's haze.

Booking Tip: Independent hiking is safe and free. Guided nature walks cost 100,000-150,000 PYG ($13-20) for 4-hour experiences. Best hiking times are 7am-10am or 4pm-6pm when temperatures are comfortable. Bring 2 liters (0.5 gallons) of water per person and sturdy walking shoes for rocky sections.

Traditional Market Food Tours

September brings seasonal specialties to Mercado Cuatro and Mercado Central as spring ingredients arrive. Vendors sell fresh surubí fish, early spring vegetables, and traditional soups like bori bori perfect for variable September weather. Morning market visits (6am-9am) offer the freshest selections and most pleasant temperatures.

Booking Tip: Food market tours typically cost 120,000-180,000 PYG ($16-24) for 3-hour experiences including tastings. Book through local food bloggers or cultural centers. Bring small bills for vendor purchases and avoid wearing expensive jewelry. Most tours include 8-10 tastings of traditional foods.

Botanical Garden and Zoo Visits

September's spring awakening makes Jardín Botánico y Zoológico spectacular as native trees bloom and animals become more active after winter. The 110-hectare (272-acre) space offers comfortable walking in variable weather, with indoor exhibits during rain showers. Spring bird migration brings unusual species not seen other times of year.

Booking Tip: Entry costs 15,000 PYG ($2) for adults. Visit early morning (8am-10am) for active animals and comfortable temperatures. The full circuit covers 5 km (3.1 miles) of walking paths. Bring insect repellent as spring rains create mosquito breeding areas near water features.

September Events & Festivals

September 14-15

Día de la Independencia Celebrations

Paraguay's Independence Day features military parades along Avenida Mariscal López, folk dance performances in Plaza de la Democracia, and traditional music concerts. Streets fill with vendors selling chipa, empanadas, and terere. The main parade runs from 9am-noon with best viewing spots along the government palace route.

Mid to Late September

Festival de la Primavera

Spring festival celebrating seasonal renewal with outdoor concerts in Parque Ñu Guazú, artisan fairs featuring traditional crafts, and food festivals highlighting spring ingredients. Local families gather for traditional asados (barbecues) throughout the city's parks and plazas.

Essential Tips

What to Pack

Lightweight rain jacket or poncho - September showers last 45-60 minutes and arrive without warning, especially between 2pm-5pm

Layered clothing system - morning temperatures at 16°C (61°F) require light sweater, afternoons at 28°C (82°F) need t-shirts

Comfortable walking shoes with good grip - cobblestone streets in historic center become slippery when wet from spring rains

SPF 50+ sunscreen - September UV index of 8 causes burns within 15 minutes despite moderate temperatures

Light scarf or shawl - evening temperatures drop quickly after sunset, and many restaurants have outdoor seating

Insect repellent with DEET - spring rains create mosquito breeding areas, especially near Paraguay River waterfront

Waterproof bag for electronics - protect cameras and phones during unpredictable spring downpours

Cash in small bills - many local vendors, market stalls, and traditional restaurants don't accept cards

Reusable water bottle - September heat and humidity at 70% requires constant hydration during outdoor activities

Light cotton or linen clothing - avoid synthetic fabrics that trap moisture in humid spring conditions

Insider Knowledge

Locals drink terere (cold herbal tea) religiously in September as temperatures warm up - try it at Costanera Sur waterfront where families gather with their thermoses and metal straws

The best exchange rates are at casa de cambio shops along Palma Street between Oliva and Chile - avoid airport exchanges which offer 15-20% less favorable rates

September winds make outdoor dining uncomfortable on restaurant terraces - choose indoor seating or establishments with windbreaks during lunch hours

Bus fare increases occurred in January 2025 - city buses now cost 3,500 PYG (about $0.50) instead of previous 2,800 PYG, and you need exact change or prepaid card

Avoid These Mistakes

Underestimating temperature swings - tourists pack only for warm weather and freeze during 16°C (61°F) mornings or get caught without rain gear during afternoon storms

Planning too many outdoor activities - September's unpredictable weather requires flexible schedules with indoor backup options like museums or shopping centers

Ignoring Independence Day closures - September 14-15 sees most businesses, banks, and government offices closed, so plan accordingly for cash needs and restaurant reservations
