Many women notice that bacterial vaginosis (BV) seems to occur more often during the summer months. Heat, sweating, prolonged moisture, swimming, tighter clothing, travel, and changes in routine can all affect the vaginal environment and contribute to BV flare-ups.
BV is not considered a sexually transmitted infection, but sexual activity can influence the vaginal microbiome and increase the likelihood of developing symptoms.
Summer often brings vacations, swimming pools, beach trips, outdoor activities, and increased travel.
Unfortunately, it can also bring an increase in vaginal health concerns.
One of the most common conditions women experience during the warmer months is bacterial vaginosis, often called BV.
Many women are surprised when symptoms seem to appear suddenly during summer, even when they have not changed anything significant in their daily routine.
The reality is that several seasonal factors can affect the vaginal environment and make BV more likely to occur.
Bacterial vaginosis occurs when the natural balance of bacteria in the vagina becomes disrupted.
A healthy vagina contains beneficial bacteria that help maintain an acidic environment and protect against overgrowth of other organisms.
When that balance shifts, certain bacteria can multiply more rapidly, leading to BV symptoms.
BV is one of the most common vaginal conditions affecting women of reproductive age.
Warm temperatures create conditions that can influence the vaginal microbiome.
Heat often means:
All of these factors can contribute to changes in the vaginal environment.
For some women, these changes may increase the likelihood of BV symptoms developing.
One of the most common summer habits associated with vaginal irritation is staying in a wet swimsuit for extended periods.
After swimming, moisture can remain trapped against the skin and surrounding tissues.
This prolonged moisture may contribute to irritation and changes in the local environment.
While a wet swimsuit does not directly cause BV, it may create conditions that make symptoms more likely in some women.
Many women notice vaginal symptoms while traveling.
Travel often involves:
These routine disruptions can sometimes affect the body's natural balance and contribute to vaginal symptoms.
Although BV is not classified as a sexually transmitted infection, sexual activity can influence vaginal bacterial balance.
Some women notice symptoms:
This does not mean an STI is present, but it does mean that symptoms should not be ignored.
If symptoms develop, evaluation may be appropriate.
Some women have very noticeable symptoms.
Others may have only mild changes.
One reason evaluation can be important is that BV symptoms may overlap with other conditions.
Symptoms of:
Can sometimes appear similar.
Proper diagnosis helps ensure the correct treatment.
Prompt evaluation can help identify the cause and guide treatment.
While BV cannot always be prevented, some habits may help reduce the likelihood of flare-ups.
Small changes can sometimes make a significant difference.
These symptoms should still be monitored, especially if they persist.
These symptoms may require additional evaluation and treatment.
Heat, moisture, sweating, wet swimsuits, and routine changes can all affect the vaginal environment.
Pools do not directly cause BV, but prolonged moisture and time spent in wet swimsuits may contribute to conditions that allow symptoms to develop.
No. BV is not considered an STI, although sexual activity may influence vaginal bacterial balance.
Some mild cases may improve, but persistent symptoms should be evaluated by a healthcare provider.
Testing or evaluation may help confirm the diagnosis and rule out other conditions with similar symptoms.
Many women are unsure whether their symptoms are BV, a yeast infection, irritation, or something else entirely.
A telehealth visit may help if:
With CallOnDoc, women can receive convenient, confidential evaluation and treatment recommendations without needing to wait for an in-person appointment.
Bacterial vaginosis is one of the most common vaginal health concerns women experience during the summer months.
While heat, moisture, travel, and routine changes can all contribute to symptoms, understanding common triggers can help women recognize problems earlier and seek care when needed.
If symptoms develop, worsen, or continue returning, a medical evaluation can help identify the cause and determine the most appropriate treatment plan.

The Call-On-Doc Guide to Bacterial Vaginosis
Bacterial vaginosis (BV) is a common vaginal condition caused by an imbalance of the natural bacteria that normally live in the vagina. It occurs when “good” lactobacilli decrease and other bacteria overgrow. BV is not considered a classic sexually transmitted infection, but sexual activity can increase the risk of developing it.
BV is most common in people of reproductive age and can recur even after treatment. While it is often mild, untreated BV can increase the risk of other infections and pregnancy complications.
