Weather in Newcastle

Stay informed about weather conditions when planning your visit to Newcastle. Below you will find the latest information, detailed forecasts, and charts to help you prepare for your trip.

Travelers heading to Newcastle can expect a pleasant climate typical of this part of South Africa. The weather here can be described as moderately warm with distinct seasonal differences. The city offers comfortable conditions for a visit at any time of the year, although the nature of your holiday will depend on the month chosen.

The summer season, which falls between November and March here, is characterised by high temperatures: the air warms up to an average of +25°C. This is the wettest time of the year when the number of rainy days is at its maximum, so an umbrella will be an essential accessory. Winter (June–August), on the other hand, brings coolness and dryness. Days remain sunny, but nights can be quite cold, with temperatures dropping to +3°C.

The main feature of the local weather is the clear contrast between the humid summer and the arid winter. The transitional seasons, spring and autumn, delight with mild warmth and moderate rainfall, making them the ideal time for those who wish to avoid both the summer humidity and the winter night chill.

The climate in the city of Newcastle is distinguished by marked seasonality, but without extreme temperature records. The warmest period is traditionally the summer months (from November to February), when the daytime air warms up to an average of +25°C. This time of year is characterised by pleasant warmth that rarely turns into stifling heat, while nights remain mild and comfortable with temperatures around +14°C.

In winter, which lasts from June to August in the Southern Hemisphere, the picture changes. June and July are considered the coldest months: the average temperature drops to +10...+11°C. A characteristic feature of the local climate during this period is the significant range between daytime and nighttime readings. While the sun may warm the air to a quite pleasant +18°C during the day, at night the thermometer drops sharply to +3...+4°C, so warm clothing for evening outings will be mandatory.

Transitional seasons, such as April and September, offer the most balanced conditions. At this time, daytime highs hold steady at +21...+24°C, creating the perfect atmosphere for sightseeing without the risk of freezing or overheating. The gradual rise in temperature in spring and its smooth decline in autumn make climatic conditions in the region predictable and favourable for tourists.

The precipitation pattern in the city of Newcastle has a distinct seasonality typical for this region of South Africa. There is a clear division into a wet summer season and a dry winter. Travelers should take into account that the main rains fall during the warm months, while precipitation is extremely rare during the cool time of year.

The wettest period lasts from November to February. The peak of rainy weather occurs in December, when an average of about 22 days with precipitation is recorded. In January and February, it also rains frequently — from 16 to 17 days a month. Usually, these are summer downpours or thunderstorms, which can be intense but are often quickly replaced by sunshine.

The winter months, especially June and July, are the driest of the year. During this time, the probability of precipitation is minimal: statistics show an average of just one rainy day per month. Transitional seasons, such as May and September, are characterised by a moderate amount of moisture, smoothly preparing nature for the change in climatic conditions.

When packing your suitcase for Newcastle, it is important to consider the reverse seasonality of the Southern Hemisphere and the nature of local rainfall. Summer lasts here from December to February and is distinguished by warm but quite rainy weather. During this period, you will definitely need light, breathable garments made from natural fabrics, as well as a reliable umbrella or high-quality raincoat, since the number of rainy days can reach 20 per month. Footwear should be not only comfortable but preferably waterproof or quick-drying.

Winter months (June–August), conversely, are very dry but are characterised by sharp temperature changes. During the day, the air warms up to a comfortable +18°C, but at night the thermometer can drop to +3°C. For this time of year, the principle of layering is ideal: during the day you can walk in a t-shirt or shirt, but for the evening and early morning, be sure to bring a warm sweater, fleece jacket, and windbreaker. A scarf will also not be amiss for the cold morning hours.

Regardless of the season, when traveling around South Africa, do not forget about protection from ultraviolet radiation. Even in winter, the sun shines brightly here, so sunglasses, headwear, and SPF cream should be in your luggage all year round. Also, ensure you have a pair of proven comfortable flat shoes for long walks around the city and its surroundings.
