Weather in New York City in June

A good month. June is a solid month to be in New York City. Highs average 22.4 °C, lows 17.2 °C, and rain falls on 14 days — nothing in the month is working against you.

June ranks 4 of 12 in New York City: past the worst of the year but short of September, which is the month to book if the dates are open.

Rain on 14 days, 4 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: it never really gets hot: not one day in an average June reaches 30 °C; the day barely swings — 5.2 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest June day reached 30.8 °C and the coldest night fell to 9.7 °C, and the wettest single day dropped 88 mm — roughly 77% of the month's rain in one day.

June is moderately variable: 42 mm in the driest year against 219 mm in the wettest, around an average of 115 mm. Roughly two Junes in three land near that average, and the third does something else entirely.

Wind is light at 11.5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 83%, high enough to notice on the warm days without dominating them.

How June sits in the year

The month is on the way up: 5.4 °C warmer than May, and July adds another 3.8 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in June

June is at or near the longest days of New York City's year: 15.1 hours of daylight, holding steady all month. Evenings are the real gain — dinner outdoors still happens in full light.

Sea temperature

The sea sits at about 18.3 °C in June — swimmable, but it takes a moment to commit. The sea peaks at 24.4 °C in August and bottoms out at 6.8 °C — water lags the air by a month or two, which is why the best swimming often comes after the best weather.

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.

June in New York City versus nearby

If New York City is one option among several, the nearby comparison is worth making. Philadelphia is close enough to be a coin toss — 4.5 °C warmer, the same number of rain days. Boston is close enough to be a coin toss — within a degree on temperature, 1 day less rain.

So: June works, with September the better month by 9 points if the dates can move. If they cannot, nothing here should stop you booking.
