Autumn comes gradually: September is practically indistinguishable from summer in terms of temperature regime, maintaining an average temperature of around 26°C, and it only becomes noticeably fresher by November.

Precipitation in St Marys is distributed unevenly throughout the year, forming clearly defined seasons.

The wettest period falls on summer and the beginning of autumn. From June to September, the number of days with precipitation increases significantly. The rainiest month in terms of frequency is considered to be August, when about 24 rainy days are recorded. At this time of year, it rains often, but judging by the small volume of falling moisture, the rains usually take the form of short-term warm downpours or drizzle, which are quickly replaced by sunshine.

Winter and early spring, on the contrary, are considered the driest times of the year. From November to April, the probability of precipitation decreases noticeably. For example, in January and December, only about 7 days with precipitation are observed per month. This makes the winter and spring periods the most favorable for those who prefer stable weather for walks in the fresh air without the need to constantly carry an umbrella.

Be sure to put a hat, quality sunglasses, and cream with a high SPF level in your suitcase to protect yourself from the active sun during walks.

If your trip falls during the summer months or early autumn, special attention should be paid to protection from moisture. According to statistics, in July and August, it can rain for more than 20 days a month, so a compact umbrella or a light raincoat will become your best friends. Due to the high humidity and frequent precipitation, it is recommended to choose quick-drying clothing and comfortable, non-slip shoes that are not afraid of water.

Winter in St Marys is mild and comfortable, but evenings and mornings can be quite fresh when the thermometer drops to 8–10°C. For a trip in the period from November to March, it is best to stick to the principle of layering: take a jumper, a fleece sweater, or a light jacket with you, which can be easily removed during the day and put on in the evening. At any time of year, you will need a pair of proven and comfortable walking shoes to explore the city.
