Get ready for a real temperature swing tomorrow in Barrinha, with the day starting off quite fresh but turning into a noticeably warm afternoon. The morning will feel crisp and pleasant, but by midday the sun will be intense and the air will take on a dry, baking quality.

Temperatures will climb from a low of 13°C in the early hours to a high of 29°C later on, so you will definitely feel that dramatic shift. With humidity sitting at 56 percent, the heat won't feel oppressively sticky, but the strong sun will make it feel warmer than the thermometer suggests, especially around midday.

There is no chance of rain at all, and the wind will be a steady 20 km/h, which could provide a bit of relief during the hottest part of the day. The UV index is very high at 8.4, so the sun's rays will be especially strong.

If you are heading out, plan for layers that you can peel off as the day warms up, and definitely bring sunscreen and a hat. The morning is ideal for any outdoor activities before the heat peaks, and the dry, sunny conditions will make for a great day overall.
