What Are the Warmest Cities in New Hampshire?

In this article I’m going to share with you my ranking of the warmest places in New Hampshire.

I created my list by researching data provided by the National Oceanic and Atmospheric Administration and other climate data providers.

Below I’m listing the top 10 warmest places in New Hampshire that have the highest average yearly temperatures. Later in the article I share a table with 20 most populous cities in New Hampshire.

Top 10 Warmest Cities in New Hampshire

Here are the top 10 warmest places in New Hampshire ranked by their daily mean temperature. The annual average temperature for 20 cities I researched for this article is 46.7 °F so only the first two cities are noticeably warmer than the average.

For the top five cities I also give average winter and summer temperatures.

1. Manchester – daily mean temperature of 50.1 °F

Manchester, the most populous city in the state, is also by far the warmest city. With its average temperature of 50.1 °F, it offers the best weather in the state for those who prefer high temperatures. Of course, Manchester is not a warm city by any means. But it offers some of the mildest winters in New Hampshire with an average high temperature of 34-39 °F and lows of 17-24 °F. Summer averages go into the 79-84 °F range while lows drop to 58-64 °F.

Compared to other cities on this list, Manchester has by far the highest daily mean temperature. It also has some of the lowest snowfall in this ranking, at 52.8 inches a year. Of course, we’re still talking about New England so don’t expect warm weather outside of the summer.

Winter temperatures: highs of 34-39 °F, lows of 17-24 °F

Summer temperatures: highs of 79-84 °F, lows of 58-64 °F

2. Nashua – daily mean temperature of 48.7 °F

Nashua is the second largest city in NH and the second warmest city in the state, too. While it has similar average maximums to Manchester (the temperatures are almost the same year round), the average minimums are noticeably lower. For example, New Hampshire’s second warmest city records winter nighttime temperatures falling to 14-21 °F compared to 17-24 °F in Manchester. If you don’t mind colder nights, Nashua still has some of the best weather in the state and is a great place to live if you want warmer weather.

Winter temperatures: highs of 34-40 °F, lows of 14-21 °F

Summer temperatures: highs of 78-84 °F, lows of 56-61 °F

3. Hudson – daily mean temperature of 47.9 °F

Hudson is a city of 25,000 people, located across the Merrimack River from Nashua. The city is colder year round, with lower temperatures and significantly more snow (66.8 inches compared to 52.9 in Nashua). If you want a relatively warm but snowy winter, Hudson is one of the best places in the state.

Winter temperatures: highs of 34-39 °F, lows of 13-20 °F

Summer temperatures: highs of 78-83 °F, lows of 56-61 °F

4. Hampstead – daily mean temperature of 47.75 °F

Hampstead is a town of 9,000 residents situated in the southeastern corner of the state, about 20 miles northeast of Nashua. Hampstead has higher minimums that Hudson, meaning it has slightly warmer nights throughout the year. It has cooler summers, with average highs reaching 76-82 °F.

Winter temperatures: highs of 34-39 °F, lows of 15-21 °F

Summer temperatures: highs of 76-82 °F, lows of 54-60 °F

5. Rochester – daily mean temperature of 47.7 °F

Rochester is a city of about 33,000 inhabitants, located on the border with Maine, 37 miles northeast of Hampstead. It has a similar climate to Hampstead with small differences in temperature.

Winter temperatures: highs of 33-37 °F, lows of 15-22 °F

Summer temperatures: highs of 77-82 °F, lows of 54-60 °F

6. Hampton – daily mean temperature of 47.7 °F

Hampton (or more precisely, the village of Hampton Beach) is the only city on this list that’s directly located on the Atlantic Coast. The moderating effect of the ocean is particularly visible during the summer, with maximums around 74-80 °F which is much lower than, for example, 78-84 °F in Manchester. If you prefer mild weather with cooler summers, Hampton may be your best option in NH.

7. Durham – daily mean temperature of 47.65 °F

Durham is situated 18 miles northwest of Hampton, on the Oyster River that connects with the Great Bay Estuary. About 16,000 people call Durham home. Since Durham is further inland, it has summers with maximums up to 3 degrees higher than in Hampton.

8. Portsmouth – daily mean temperature of 47.6 °F

Portsmouth lies on the Piscataqua River that drains into the Atlantic Ocean and provides the border between New Hampshire and Maine. This city of 22,000 residents shares a similar ocean-influenced climate to Hampton which is located about 13 miles southwest.

9. Epping – daily mean temperature of 47.4 °F

Epping, a town of 7,000 residents, lies 16 miles northwest of Hampton and 12 miles southwest of Durham. It has the same climate as Durham.

10. Concord – daily mean temperature of 47.2 °F

Concord is the capital city of the state. Located 35 miles north of Nashua, Concord experiences colder winters with highs of 31-35 °F and lows of 13-19 °F. Summers in Concord are cooler by about a degree than in Nashua. The city also gets much more snow: 67.7 inches and 30 days of snow compared to 52.9 inches and 19 days of snow in Nashua. Despite colder weather, Concord gets 2,519 sunshine hours a year, with sun shining 44% of the time in the cloudiest month of November.

I created the table below by researching data for the most populous municipalities in New Hampshire. When I couldn’t find data for a given city, I moved on to another. While the list includes 20 cities, some of the bigger cities may be missing because there was no data for them. Please check the closest geographically city then.
