Stepping outside tomorrow in Barrinha, the first thing you will notice is that brilliant, unblinking sunshine. It will feel warm and pleasant, not oppressively hot, thanks to the relatively low humidity for this region at 56 percent. The air will be dry enough to make the heat feel crisp and manageable.

The day will swing from a cool morning low of 13 degrees to a high of 29 degrees in the afternoon, so you will want layers. That morning chill will burn off quickly, and by mid day, the humidity combined with the sun will make it feel a bit warmer than the thermometer reads. Keep in mind that the UV index is high at 8.4, so unprotected skin can burn fast despite the dry air.

There is zero chance of rain, with no precipitation expected, so you can leave the umbrella at home entirely. A steady wind from the north or northeast will blow at 20 kilometers per hour, which will feel like a welcome breeze against the afternoon warmth. That wind will help keep the air from feeling stuffy, though it may kick up a little dust in open areas.

For planning your day, the biggest takeaway is sun protection. Wear a hat, apply sunscreen, and bring a light jacket for the morning and evening. The breeze will be your friend during the hottest part of the day, so consider outdoor activities in the late morning or late afternoon when the sun is less intense.
