In Santa Rita, heat sets the agenda in summer: summer highs sit around 31–33 °C and can reach 38 °C (Wikipedia PT (opens in a new tab)). The working rule is simple: be outdoors before 10 am and after 5 pm, spend the middle of the day eating and resting indoors, and always have a fallback for storms, because it rains here every month of the year.
What is Santa Rita's weather like through the year?
- Summer (December to February): hot and humid, highs of 31–33 °C and peaks of 38 °C (Wikipedia PT (opens in a new tab)). This is when splitting the day into blocks pays off most.
- Winter: mild, but cold fronts roll in from the south; lows can drop to 0–3 °C, with light frost in low-lying spots (same source). Afternoons are the best time for walking.
- Rain: 1,800–2,000 mm a year, spread across every month (same source). There is no dry season when you can leave the umbrella behind.
When should you do what in summer?
Paraguay's Health Ministry and the IPS social security institute advise staying out of the sun from 10:00 to 17:00, when radiation is strongest, and exercising before or after that window (ABC Color, February 2026 (opens in a new tab)). In Santa Rita that looks like this:
- 7:00–10:00: anything outdoors. The Túnel Verde, the tree-covered stretch of Route PY06 in barrio 14 de Mayo, is shaded in the morning (Última Hora (opens in a new tab)). It is also the time for errands, big shopping trips and sport.
- 10:00–17:00: lunch, siesta and anything indoors or air-conditioned. If you need to drive to Ciudad del Este (about 70 km), do it now in a cooled car rather than walking in the sun.
- After 17:00: plazas, cycling, a walk or a loop through the centre until dark.

What to carry and how much to drink
- Actual water: during the February 2026 heatwave, the Health Ministry and IPS advised 3–4 litres of water a day without waiting to feel thirsty, and pointed out that tereré (iced yerba mate) does not replace water (ABC Color (opens in a new tab)).
- Clothing: light, pale and loose, plus a hat, UV sunglasses and sunscreen even on cloudy days (same source).
- In the car: never leave children or pets in a parked vehicle, not even for a minute.
- People at risk: children, over-60s and anyone with a chronic condition. Older people should be in an air-conditioned room with company during the hottest hours (same source).
What if someone gets sick from the heat?
Dizziness, nausea and feeling generally unwell are warning signs, according to a Health Ministry cardiologist quoted by ABC Color (2022) (opens in a new tab). Move the person somewhere cool, lay them down with legs raised and cool them with wet cloths; if their skin is hot or they are confused or delirious, call an ambulance right away (same source).
In Santa Rita the public hospital is the Hospital Distrital; in September 2025 it was the only hospital in southern Alto Paraná with a 24-hour ambulance (La Nación (opens in a new tab)). Save its number when you arrive.
Storms and power cuts: the other side of summer
Strong heat is often followed by a windy storm. In October 2023 a storm damaged about 450 homes in Santa Rita municipality and brought down ANDE power poles across the south of the department (La Nación (opens in a new tab)); in March 2021 another one ripped roofs off businesses and dropped branches in the Túnel Verde itself (Última Hora (opens in a new tab)).
- Check the forecast in the morning and, if a storm is coming, move outdoor plans earlier.
- Don't park or wait under big trees in strong wind.
- Keep your phone charged, a torch handy and some water stored: when the power goes, so does the air conditioning.
When is the best time to visit Santa Rita?
If you can choose, come between late April and May: that is when the Expo Santa Rita and the 22 May patron saint festival take place, and the heat has eased (see our Santa Rita travel guide). In winter you can walk comfortably at any hour, but pack a jacket for the evening. Midsummer works too, as long as you plan the day around the sun; for a two-day plan, read a weekend in Santa Rita.
