Climate Chart of New York City, USA

Monthly data: Temperature °C, Rain (mm), Sunshine (h) · 2013–2023

Climate overview

Temperature

Monthly mean temperature is coolest in January, at -0.2 °C, and warmest in July, at 24.5 °C. These are averages for each month, not typical daytime highs, so they describe the overall monthly temperature pattern rather than the warmth visitors should expect at a particular hour. Across the calendar months, the unweighted mean of monthly mean temperatures is 12.0 °C. It summarizes the monthly averages without accounting for how many days each month contains.

Rain

Mean daily rainfall reaches its monthly high in July, at 4.40 mm/day, and its low in January, at 2.14 mm/day. These daily averages are not monthly totals and do not show how rainfall is distributed from day to day. The unweighted mean across the monthly mean daily rainfall figures is 3.14 mm/day. It provides a year-round reference, but cannot indicate the chance of rain on a specific date.

Sunshine

Mean daily sunshine duration is highest in July, at 11.45 hours/day, and lowest in December, at 5.20 hours/day. These figures can help with broad outdoor-planning expectations, but sunshine duration is not the same as day length. The unweighted mean of the monthly mean daily sunshine figures is 8.27 hours/day, a broad summary rather than a forecast for any particular day.

Snow

Mean daily snowfall reaches its monthly high in February, at 8.50 mm/day. This is an average amount, not a measure of snowy-day frequency, snow depth, snow cover, or suitability for skiing. The unweighted mean across the monthly mean daily snowfall figures is 1.92 mm/day. It offers a broad summary of the supplied averages, but does not establish how often snow falls.

Best Travel Time Guide for New York City, USA: Ideal Seasons and Weather Insights

Visitors prioritising cooler monthly averages may consider January, when the monthly mean temperature is -0.2 °C; this is a monthly average, not a promise of cool conditions throughout every day. For lower average rainfall, January is the conditional option, with mean daily rainfall of 2.14 mm/day, but that figure neither guarantees dry days nor quantifies rain frequency. Plan for rain variability if travelling in July, which has the highest monthly mean daily rainfall at 4.40 mm/day; carrying suitable rain protection is a practical precaution, though the average cannot predict conditions on a particular date.

For outdoor plans that benefit from more average daily sunshine, July records 11.45 hours/day; December records the lowest mean daily sunshine, at 5.20 hours/day. These averages can inform daylight planning, but sunshine duration is not day length and does not guarantee clear skies. The different criteria point to different considerations rather than one universal best time to visit. The recorded snowfall average peaks in February at 8.50 mm/day of mean daily snowfall. Treat this as an average amount only: it cannot tell you whether snow will fall during a visit or establish snow depth, cover, or skiing conditions.
