Weather in Virginia Beach in September

Prime time. If you get to pick your dates, September is the one. Highs average 26.2 °C, lows 20.2 °C, and rain falls on 11 days — nothing in the month is working against you.

September ranks 2 of 12 in Virginia Beach. Only October scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 11 days, 3 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

Averages flatten a month, and this one hides a few things: the day barely swings — 6 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest September day reached 33.9 °C and the coldest night fell to 12.5 °C, and the wettest single day dropped 145 mm — roughly 112% of the month's rain in one day.

September is moderately variable: 16 mm in the driest year against 292 mm in the wettest, around an average of 130 mm. Roughly two Septembers in three land near that average, and the third does something else entirely.

Wind is light at 12.4 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 78%, high enough to notice on the warm days without dominating them.

How September sits in the year

The month is on the way down: 3.1 °C cooler than August, with October dropping another 5.1 °C. The first week and the last are not the same trip.

Daylight in September

12.5 hours of daylight, losing 1.2 hours across the month. That is between Virginia Beach's extremes of 14.7 and 9.7 hours, so days are long enough not to constrain the plan.

Sea temperature

The sea sits at about 23.6 °C in September — comfortable for a proper swim. This is the warmest the water gets all year.

How busy it gets

Busy. Popular without being frantic; book the things you care about, improvise the rest.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

September in Virginia Beach versus nearby

If Virginia Beach is one option among several, the nearby comparison is worth making. Richmond is close enough to be a coin toss — 8 °C cooler, the same number of rain days. Washington is close enough to be a coin toss — within a degree on temperature, 1 day less rain.

So: September is effectively as good as it gets here — 5 points behind October, which is inside the margin where the weather stops being the deciding factor and price starts being it.
