May ushers in genuine autumn colour in parks around Parque Rodó and Prado, with cool, fresh mornings and tops in the low-to-mid teens Celsius. Windy spells from the south clear the sky and make evenings feel colder - a warm sweater and a rainproof layer are advisable. Travel is quieter, prices are lower, and cultural venues are easier to book, though outdoor swimming is essentially over.
May introduces cooler, windier conditions and the low hills inland start to green after spring rains; daytime highs are comfortable in the mid-teens Celsius. Many beach facilities close for the low season and the area becomes quieter - ideal for travelers who prefer a slower pace and coastal drives without crowds. Nights can be chilly; a midweight jacket is useful for seaside dining.
By May the coastline quiets considerably and strong southerly winds become more frequent, lending a wild character to the beaches. Seasonal closures increase and many restaurants limit hours; independent travellers should stock up on supplies in La Paloma or Rocha town. Cooler days are ideal for inland hikes and exploring the broad estuaries without the summer dust and heat.
May sees cooler, blustery days and an unmistakable lull in tourist services; many small riverside cafés reduce hours for the low season. Daylight shortens and evening air becomes nippy, so a warm layer is needed for alfresco meals. The quieter roads and lower rates are ideal if you prefer a tranquil visit to Colonia’s heritage sites and Carmelo’s boutique wineries.

May introduces noticeably cooler weather and the landscape’s pastel tones; frost can hit in some low-lying places at the month’s end, though hard freezes are not widespread. Daytime activities such as thermal baths remain enjoyable but the water feels especially comforting against cooler air. Many rural attractions slow services for winter, so check opening times if scheduling remote estancia stays.
There are no major festivals or events in Uruguay during May to be aware of.
