Climate - Naples (Florida)

The climate of Naples is almost tropical, with pleasantly warm winters and hot, humid summers, during which there are quite frequent thunderstorms.
The city is located in southwestern Florida, on the Gulf of Mexico coast.
The average temperature of the coldest month (January) is of 18.5 °C (65.4 °F), that of the warmest month (August) is of 28.5 °C (83.4 °F). Here are the average temperatures.

Precipitation amounts to 1,260 millimeters (49.6 inches) per year: it is therefore quite abundant. It ranges from 35 mm (1.4 in) in the driest months (February, November, December) to 225 mm (8.9 in) in the wettest (August). Here is the average precipitation.

The winter, from December to February, is pleasantly warm and sunny.
The rains are quite rare.
There are several warm periods, in which the temperature reaches or exceeds 28 °C (82 °F). There are also cooler and windier periods, usually of short duration, in which the night temperature drops below 10 °C (50 °F), and sometimes up to 5 °C (41 °F), while the maximum temperatures remain around 15 °C (59 °F).
In addition, short cold spells can sometimes occur, during which the minimum temperature drops to around freezing. However, these cold spells are less intense than in north-central Florida. The temperature drops below freezing once every ten years. The record is -1.5 °C (29.5 °F), set in December 1989 and in February 1996.
Snow in Naples is extremely rare, actually, it has probably never snowed since the end of the nineteenth century.

The summer, from June to September, is hot and muggy. Due to high humidity, the heat is sweltering. The combination of humidity and temperature can produce a perceived temperature of 40 °C (104 °F) and above.
On the hottest days of the year, the temperature usually reaches 35/36 °C (95/97 °F).
The sun often shines, but the sky is not always clear, as cloud coverings can form, which can give rise to thunderstorms. In summer, thunderstorms break almost every day, although it doesn't always rain. There can also be hail and gusts of wind.
Between late summer and early autumn, Naples can be affected by hurricanes or tropical storms. Hurricane season runs from June to November, although the period in which they are most likely is from August to October. Generally, hurricanes come from the east or south and therefore do not hit Naples directly, as it faces west, however it is potentially at risk as it is developed along the coast. In fact, from time to time a hurricane can hit Florida coming from the southwest and directly affect this area, as happened with hurricane Charley in August 2004 and Ian in late September 2022.

In spring and autumn, from March to May and from early October to late November, it is generally warm to hot and sunny. The rains are not very frequent.
In May and October it is almost as hot as in summer, even though the humidity is lower and the rains are less frequent.
In March and November, on the other hand, there can be outbreaks of cold air that can bring a bit of cold at night.



The sea temperature ranges between 22 °C (72 °F) and 30 °C (86 °F). The sea is warm enough for swimming from April to December. In winter it is a bit cool, but all in all it is acceptable. Here are the average sea temperatures.

From time to time, Naples can be affected by tornadoes. Tornadoes in Florida typically form from May to October (but sometimes also in January and February), during thunderstorms, and are more frequent but less dangerous than in the south-central United States.

Best Time

To visit Naples you can choose the period from mid-March to mid-April. In winter, however, there are long pleasant periods.
To go to the beach, in May the weather is generally good, with fewer thunderstorms than in summer. Even in April, the temperature is generally warm enough, although occasionally there can be some cool days, with lows around 15 °C (59 °F) and highs around 22 °C (72 °F).
