You wake up one morning and notice raised, red welts spreading across your arms or torso. They itch intensely. They weren't there yesterday. You haven't changed your detergent or tried a new food. So what's going on?
For many South Florida residents, late April is prime time for this exact scenario. Allergy season is in full swing, and the same environmental triggers causing runny noses and watery eyes can also send your skin into a reactive spiral. Hives, also known as urticaria, are one of the most common skin reactions tied to allergen exposure. And in South Florida, those allergens are everywhere right now.
South Florida's climate is unlike most of the country. Warm temperatures, high humidity, and year-round plant activity mean pollen counts don't follow a tidy seasonal schedule. But late spring brings a notable surge in airborne allergens, including tree pollen, grass pollen, and mold spores that thrive in humid conditions.
When your immune system overreacts to one of these triggers, it releases histamine into the skin. That histamine response causes the classic signs of hives:
Beyond airborne allergens, South Florida's lifestyle adds more potential triggers into the mix. Sunscreen ingredients, insect bites, outdoor foods at spring gatherings, heat, and sweat can all contribute. If you've noticed your skin reacting more this time of year, you're not imagining it.
Not all hives are the same, and the distinction matters when it comes to treatment.
Acute urticaria lasts less than six weeks and is often tied to a specific trigger, such as a food, medication, insect sting, or viral illness. Many cases resolve on their own or with over-the-counter antihistamines once the trigger is removed.
Chronic urticaria lasts longer than six weeks, often with no clear cause. This form is more common than many people realize and can be frustrating to manage without professional guidance. Chronic hives may come and go over months or even years, and they can significantly affect sleep, concentration, and quality of life.
Other allergic skin reactions that tend to flare this time of year include:
Getting an accurate diagnosis matters, because the right treatment depends entirely on what's actually driving the reaction. If you've been dealing with recurring eczema flare-ups alongside hives, a dermatologist can help sort out what's what.
Many patients assume hives are always an allergist's territory. In some cases, that's true. But when the skin itself is significantly involved, or when reactions are chronic and difficult to identify, a board-certified dermatologist is an essential part of the care team.
You should schedule an appointment with a dermatologist if:
Seek emergency care immediately if hives are accompanied by difficulty breathing, throat tightening, dizziness, or chest pain. These can be signs of anaphylaxis, a serious allergic reaction that requires urgent medical attention.
It's also worth noting that some medications commonly used this time of year, including certain allergy drugs and NSAIDs, can themselves trigger or worsen hives. A dermatologist can help piece together that timeline. For patients wondering whether their sunscreen is causing skin reactions, that's a surprisingly common issue in South Florida and worth exploring with a specialist.
