La Plata faces a cold, dry Wednesday, June 17, 2026, with a forecast high of 13°C and a low of 5°C. The Servicio Meteorológico Nacional says no rain is expected at any point in the day, even as light to moderate winds move through the morning, afternoon and night.
That is the reason people in La Plata are checking the forecast now: the day begins at 5°C and never really warms much beyond a cool 13°C, with 78% average humidity adding to the sharp feel in the air. In the early hours, the forecast calls for no rain and south winds at 13 km/h. By mid-morning, humidity rises to 86% and winds ease from the southeast at 12 km/h, still with no rain. The afternoon stays dry with east winds at 15 km/h, and night brings no precipitation and east winds at 18 km/h.
The strange part of the forecast is what sits beside it. The same weather bulletin that clears the day of rain also spends time on alert definitions, including warnings for rain, storms, extreme temperatures and other unusual conditions. That matters because the absence of precipitation does not mean the day is harmless; cold mornings and evenings can still shape travel, errands and outdoor plans, especially when the air stays damp and the wind keeps moving.
For now, the best reading is simple: Wednesday in La Plata is set up to be dry, chilly and breezy, with the most uncomfortable stretch likely to come before sunrise and again after dark. The forecast leaves one open question that matters to anyone planning around it: whether the conditions will stay unchanged through the day or be updated later, as weather bulletins sometimes are.
