Best Time to Visit Puglia for Swimming: Water Temperatures by Season
Quick Summary: Swimming Season in Puglia
Swimming season runs May through October, with July-September offering the warmest water (25-28°C). May and October are swimmable but cool (18-20°C). Water below 18°C requires a wetsuit for most people. If comfortable water temperature is your priority, plan your visit for late June through mid-September.
Monthly Water Temperature Guide
May: Spring Swimming (18-20°C / 64-68°F)
Best for: Experienced swimmers, athletes, dedicated beach-goers
May offers beautiful weather—sunny, 22-25°C air temperature—but the water is refreshing rather than warm.
June: Early Summer (21-23°C / 70-73°F)
Best for: Those wanting decent water without peak summer
This is the "sweet spot" for many travelers. Water is warming noticeably, days are long, and crowds are moderate.
July-August: Peak Summer (26-28°C / 79-82°F)
Best for: Maximum water enjoyment, peak beach season
This is when the sea is at its warmest and most inviting. However, this is also peak season: beaches are crowded, hotels fully booked, and prices at maximum.
September: Late Summer (24-26°C / 75-79°F)
Best for: Ideal balance of warm water, smaller crowds, better prices
September is many travelers' favorite month. Water is still warm enough for comfortable swimming (24-26°C), but crowds drop significantly after Labor Day.
October: Autumn Swimming (20-22°C / 68-72°F)
Best for: Adventurous swimmers, those wanting fewer tourists
October is swimmable but becoming cool. Air temperature is still pleasant (20-22°C during day), but water temperature drops.
The Verdict: Best Time for Swimming
If warmest water is your goal: July-August (26-28°C), but expect crowds and high prices.
If you want comfort without peak tourism: September (24-26°C, fewer crowds, reasonable prices) or early June (21-23°C, moderate crowds).
