Warm days, with a cooler edge after dark
Rio in June suits travellers who want warmth for spending time outdoors rather than persistent high heat. The average daytime high is 5.5°C above London's, and 54% of days reach 25°C. Days reaching 30°C are uncommon, so very hot weather is not the main reason to choose this month. Light clothing should work well during the day, though midday can still feel hot, particularly with humidity at 81%. Bring a light jumper or jacket for evenings: the average low is around 18°C, and colder nights can feel noticeably fresher. June is among Rio's cooler months, but that is a relative judgement, not a warning to expect British-style chill throughout.
Enough sunshine for outdoor plans, but keep them flexible
Expect some rain rather than a reliably dry holiday. June has about 7 rainy days, so a light waterproof is useful and weather-dependent plans are best kept movable. That does not mean those days are complete washouts, but you should not assume the rest will be cloudless either. Sunshine averages about 5.7 hours within 10.6 hours of daylight, leaving scope for outdoor time without promising uninterrupted blue skies. Put your most weather-sensitive plans on brighter days and avoid making every day depend on beach weather. The combination of warmth, some sunshine and some rain suits a flexible trip better than a holiday built entirely around sunbathing.
