Stay informed about the weather conditions in the city of Hayward before starting your journey. Below are current updates, forecasts, and useful charts to help you plan your day.

The climate in Hayward can be described as pleasant and moderate, reminiscent of a Mediterranean type. Thanks to its favourable geographical location, the weather here is mild all year round: the city does not experience extremely low temperatures in winter or exhausting heat in summer, making it a comfortable destination for travellers in any season.

Summer in Hayward is a time of sun and warmth. From June to September, the dry season sets in, when precipitation is almost completely absent, and the average daily temperature hovers at a comfortable +25...+26°C. This is the ideal period for active leisure and outdoor walks, as the probability of rain is reduced to zero.

The winter months, conversely, bring coolness and are the wettest period of the year. From December to March, the highest number of rainy days is observed, although the cold here is quite relative: even in January, the temperature rarely drops below +7°C at night, and during the day the air warms up to an average of +11°C. Spring and autumn serve as a smooth transition, offering tourists moderately warm weather with variable cloudiness.

The climate in Hayward is characterised by mildness and a lack of extreme fluctuations, making the city attractive to visit at any time of the year. The coolest months are traditionally December and January, when the average temperature stays around 10–11°C. During this period, night-time readings drop to 6–7°C, but severe frosts are an extremely rare phenomenon here. During the day, even in winter, the air often warms up to a comfortable 14–16°C.

The summer season is characterised by pleasant warmth without exhausting heat. The highest temperatures are recorded in July, August, and September, when the thermometer rises to 25–27°C during the day. September in this region is effectively a continuation of summer, maintaining the same high figures as August. This time is ideal for those who love sunny weather but cannot tolerate intense heat.

Travellers should pay attention to the noticeable daily temperature fluctuations characteristic of this region. Even in the warmest summer months, the difference between the daily maximum and the nightly minimum can be more than 10 degrees. After sunset, the air quickly cools down to 13–15°C, so it is recommended to always have a light jacket or sweater with you for evening walks.

Precipitation patterns in Hayward have a distinct seasonality, clearly divided into wet and dry periods. Since winter temperatures here remain above freezing, precipitation falls mainly as rain. The wettest time of the year is winter and early spring: the peak occurs in March, when about 12 rainy days are recorded, as well as in December and January with an average of 10 days with precipitation.

The summer months, on the contrary, are distinguished by exceptional dryness. From June to September, rain is a rarity, and statistics show that in the height of summer, especially in July and August, the number of rainy days tends towards zero. This makes the summer season the most predictable and comfortable for long walks in the fresh air without the risk of getting wet.

Transition periods are characterised by gradual weather changes. In April and May, the probability of precipitation decreases (about 3–4 rainy days), and by November it begins to rise again, reaching an average of 6 days with precipitation. Overall, the city's climate is quite comfortable, but if your trip is planned for the winter months, an umbrella in your luggage will not be amiss.

The climate in Hayward is mild, so the main principle when packing your suitcase should be layering. In summer and early autumn, it is warm and dry here: during the day the temperature rises to a comfortable +25...+27 °C, but evenings can be cool, when the thermometer drops to +13...+15 °C. Be sure to bring light T-shirts and shirts, but complement them with a hoodie, cardigan, or light jacket to feel cosy after sunset. Since there is practically no precipitation from June to September, do not forget sunglasses and sunscreen.

If your trip is planned for the winter period or early spring, it is worth preparing for wetter weather. Although there are no severe frosts here and the temperature stays around +10...+12 °C, it often rains from December to March (up to 10-12 rainy days per month). During this period, a waterproof windbreaker, raincoat, or compact umbrella, as well as a warm jumper, will become indispensable. Regardless of the season, comfortable flat shoes, such as trainers, are best suited for walking around the city, as you will likely want to walk a lot.
