Heat and summer weather in Jacksonville
JACKSONVILLE, Fla. – Jacksonville is officially welcoming the first day of summer, and if you’ve felt like it’s already been here for weeks, you’re not alone. Meteorologist Katie Garner, as seen on News4JAX’s Weather Authority, confirmed that today marks the summer solstice—our longest day of the year. Sunrise is at 6:25 a.m. with sunset coming late at 8:32 p.m., making this Thursday truly stand out.
The forecast calls for a high near 92 degrees, right in line with a streak of hot days. According to The Weather Authority’s Exact Track 4D, highs for the next week are predicted to remain in the low to mid 90s, with overnight lows steady in the lower 70s. While these numbers seem familiar already, the real kicker is how it feels: humidity and heat index values will likely push those feels-like temperatures into the upper 90s or even the 100s, especially into the afternoon.
The hot trend is expected to stick around. If you’re hoping for relief, the seven-day forecast doesn’t show much of a break anytime soon, but at least mornings may offer a brief window of cooler temps in the 70s.
Rain and storm forecast, including severe risk
This classic summer heat brings a good chance for storms each afternoon. Katie Garner explains that the storm window is likely to open between 3:30 p.m. and 10 p.m., with the greatest risk for stronger activity later in the day, especially for areas north and west of Jacksonville, like Brunswick and St. Marys.
Based on The Weather Authority’s radar and forecast rain chance graphics, Saturday carries a 40% chance of rain. This is expected to drop to 20% by Sunday, making for a sunnier end to the weekend. While a few storms may turn stronger, most are expected to dissipate by late evening, setting up slightly drier conditions into next week.
As always, Exact Track 4D will keep you updated as the storm risk develops.
Safety precautions: Rip currents and outdoor activity tips
Getting outdoors quickly becomes more challenging in this kind of heat. Meteorologist Katie Garner specifically reminds you to plan dog walks or any outdoor activities early in the day. Temperatures will rise fast—expect it to feel like the 90s or hotter before noon. News4JAX’s Dog Walk Forecast points out that the asphalt can be much hotter than the air temperature, so watch out for your pet’s paws. Plus, those afternoon storms can pop up quickly, so keep an eye out before heading outside.
If you’re heading toward the beaches, The Weather Authority has upgraded the rip current risk to moderate for most of central and southern Florida. While this doesn’t specify Jacksonville’s beaches directly, it’s a good reminder to swim with caution and check the local advisories before hitting the waves.
