Sunniest places to go from London in April
In April, the sunniest well-known place within 15 hours of London is Ouarzazate, Morocco, 12.2 h of sun a day and 20.8 °C, about 6h 36m each way by air. Without flying, it is Marseille, France, 11.7 h of sun a day, about 8h 54m each way by train, for about 20× less carbon (29.6 kg CO₂e return against 593 kg).
The 10 sunniest places within 15 hours of London
Ranked on sunshine in April alone, among well-known places (a Wikivoyage travel guide and at least 40,000 Wikipedia readers a year), one per area and at most three per country. The carbon is shown, not used to choose: the list further down is the other question, how much sunshine each extra kilogram buys.

≈ is the model's estimate (air times include getting to and through the airport); ✓ is a rail journey checked against a real timetable, with the date it was checked. Temperatures are historical daily means for 2023–2024, averaged across day and night, so afternoons run warmer.
The low-carbon trade-off
The sunniest place you can reach from London in April within 15 hours is Toledo, 12.1 h, costing 335 kg CO₂e return. The lowest-carbon option is Calais at 4.5 kg — 74× less carbon, for 3.1 hours less sunshine.
Every destination here is on the efficiency frontier: nowhere else this site covers is both sunnier in April and lower in carbon. Anything a better option beats outright has been left out.
By rail or ferry By air
What the 15-hour limit costs: at this budget Toledo can only be reached by air — 335 kg CO₂e, in 5h 18m. Allow up to 24 hours and the train does the same journey for 39.3 kg in 17h 30m — 9× less carbon for 12h 12m more travelling.
| Destination | How | CO₂e return | Temp | Sun/day | Rain/day | Journey |
|---|---|---|---|---|---|---|
| Calais, France | Rail | 4.5 kg | 9.6 °C | 9.0 h | 2.9 mm | 5h 24m |
| Great Yarmouth, United Kingdom | Rail | 14.2 kg | 9.0 °C | 9.5 h | 2.2 mm | 4h |
| Romans-sur-Isère, France | Rail | 24.0 kg | 11.8 °C | 10.2 h | 1.8 mm | 9h 24m |

The flights, in practice
The model measures to the town, not to a runway. For the destinations above reached by air, this is the nearest airport, how far it is, and whether a direct flight from London is listed on the airport's own destination page (researched 2026-09-15; route existence, not availability on a date). "Not checked" means no destination list was read for that airport.
| Destination | Airport | From town | Direct from London | Onward |
|---|---|---|---|---|
| Toledo, Spain | Adolfo Suárez Madrid–Barajas MAD | 80 km | yes LHR, LGW, LCY, LTN, STN | Train or metro into Madrid, then Avant train or coach to Toledo. |

Warm is not the same as pleasant, which is why sunshine and rainfall are shown alongside temperature. All three are ERA5 monthly means for 2023–2024.
Where the curve breaks
The frontier is gentle until it isn't. Going from Marseille (29.6 kg, 11.7 h) to Toledo (335 kg, 12.1 h) buys 0.4 hours more sunshine for an extra 305 kg — 762 kg of CO₂e per hour. That single step is the most expensive sunshine on the whole curve.
The pick of them

ToledoSpain335 kg CO₂e returnwarm, bright and dryThe same month, asked differently
April answers differently depending on what you are after, and the lists genuinely diverge: the brightest places are not the hottest, and in summer the useful question stops being where is warm at all.

Where is the sunniest place to go from London in April?
Toledo, Spain, at 12.1 h. Reaching it emits 335 kg CO₂e return, travelling 5h 18m each way by air (modelled).
Can I get somewhere sunny from London in April without flying?
Yes. Marseille reaches 11.7 h and is reachable by rail or ferry in 8h 54m (modelled), emitting 29.6 kg CO₂e return — though Toledo is sunnier still, if you fly.
How much carbon does a return trip from London to Toledo produce?
335 kg CO₂e for one person, return, by air. That uses the UK Government's 2026 conversion factors, including radiative forcing for flights.
Carbon uses UK Government (DESNZ/DEFRA) 2026 conversion factors applied to great-circle distance, with radiative forcing included for flights. Rail journey times are modelled estimates, not timetabled services. Full method · download the data.
