The sky will be brilliantly clear from start to finish, with that intense late-spring sunlight that feels both invigorating and sharp on the skin. Despite the high temperature, the air itself won't feel heavy, which makes the warmth more pleasant than oppressive.

Temperatures will swing from a crisp 13 degrees in the early morning to a peak of 29 degrees in the afternoon, so you will want a jacket for the start of the day and then light layers later. With humidity at 56 percent, the heat won't cling to you, making the high feel more manageable and the low feel noticeably cooler.

There is zero chance of rain tomorrow, and the wind will be a steady presence at 20 kilometers per hour, enough to rustle leaves and provide a natural breeze. The UV index is rated at 8.4, which is strong, so plan for sun protection if you are spending time outside.

My concrete advice is to get your outdoor chores or a long walk done in the morning or late afternoon, when the sun is less aggressive. Keep sunglasses and sunscreen handy, and maybe a light windbreaker for the evening, as the drop in temperature will be quick once the sun goes down.
