Summertime can be rough on your toenails. If you’ve noticed thick, brittle, or dry cracked toenails in summer, it may be more than just cosmetic wear and tear.

Dry, warm weather—combined with increased time in sandals, pools, and sweaty shoes—can weaken the nail structure. Toenails naturally lose moisture when exposed to heat and UV rays. Chlorine and salt water only make matters worse, drying out the nail bed and making cracks more likely.

But there’s another layer: cracked or brittle toenails are often linked to fungal infections or underlying health conditions like psoriasis, thyroid imbalances, or poor circulation. If your nails are discolored, thickened, or separating from the nail bed, it’s time to stop self-treating and get a podiatrist involved.

At Gauld Foot and Ankle, we evaluate the cause of toenail changes using visual exams, fungal testing, and patient history. If fungus is present, we offer both topical and oral antifungal options depending on severity. For nails damaged due to trauma, aging, or underlying skin conditions, we recommend targeted care routines that may include trimming, medical-grade moisturizers, and nutritional guidance.

We also educate our patients on toenail hygiene, especially in summer months. Tips like alternating footwear, using antibacterial sprays in shoes, and moisturizing nails regularly can make a big difference in nail health and appearance.

If you’re unsure whether your cracked toenails are something to worry about, we’re here to help. Book your appointment with Gauld Foot and Ankle and get your feet looking and feeling better for the rest of the season.
