South Florida is gearing up to experience a surge in warmth and humidity, with Miami temperatures set to hit the low- to mid-80s. According to NBC Miami's forecast, today could see a high of 81 degrees and a slim chance of showers. Runners participating in the Miami Marathon and Half Marathon should be prepared for a race that's not just dry but also distinctly warmer and more humid than ideal conditions.

As the weekend progresses, the weather is expected to become increasingly stuffy, with feels-like temperatures nearly to touch 90 degrees by the end of Sunday. On the other hand, the forecast from the National Weather Service suggests a high near 79 today and calming east winds in the afternoon. Runners are advised to stay hydrated and pace themselves as the heat intensifies.

Relief from the heat is on the horizon, with a front slated to push through next week, mitigating the mini heatwave Miami has been experiencing. This upcoming transition is forecasted to bring morning temperatures down to the 50s and afternoon highs settling in the 70s, ensuring a much cooler climate following several days of unseasonable warmth.

For those planning weekend activities, tomorrow is expected to be mostly sunny with a high of 82°, leading into a very warm and humid Sunday with a high of 84°, as reported by NBC Miami. Meanwhile, the overnight conditions maintain a pattern of moderate temperatures, with lows hanging around the 70s before the anticipated cold front arrives to seemingly wave goodbye to the heat.
