City trips and inland heat
Spring and autumn can be useful editorial choices for heritage-led city routes when the actual weather and calendar cooperate. They do not guarantee low crowds, low prices or a mild afternoon.
For exposed summer visits in inland and southern cities, shorten demanding walks, build in water and rest and keep major indoor collections as deliberate options. Check the destination forecast rather than using one national temperature.
Northern coast, Mallorca and the Canaries
Bilbao and San Sebastián need a northern-weather plan, including a suitable rain alternative. A wet day does not automatically rule out a cultural city visit, but can change coast and walking choices.
Mallorca and the Canaries are separate seasonal decisions. Even when an island coast feels mild, wind, sea state and altitude can affect an activity. Recheck local conditions and the operator’s actual programme.
Mountain and landscape access
For Teide, use current national-park and Tenerife access information for the chosen trail or activity, including any applicable permit. Conditions at altitude are not established by a town or beach forecast.
For coastal or volcanic landscapes, use official weather and access notices, not an older seasonal photograph. Keep a town-based, sheltered or rest alternative and preserve the final transfer when conditions change.
