Monaco will be cool and cloudy for first grand prix in two years

2021 Monaco Grand Prix weather

As with several other European grands prix this year, Monaco is set to see markedly cooler conditions than its previous running.

But that last occasion was two years ago. Formula 1 did not visit the principality in 2020, for the first time since 1954, due to the pandemic.

This year’s running takes place in roughly its usual calendar spot – give or take a week – but will be significantly cooler than 2019’s event.

An overall chillier and stormier May than some years in Europe will affect the principality as well, making practice sessions potentially four to five degrees cooler than in 2019. First practice in 2019 ran in 19C air temperatures, whereas this year it could be as cool as 15C, with second practice only set to be a little warmer.

With little grip available on the track surface, that it likely to prove a recipe for graining on the tyres. However both Thursday sessions should be sunny, without significant cloud cover.

Light showers are predicted on Friday, and while there’s no F1 action then, it could make life interesting for the Formula 2 drivers. Any precipitation is unlikely to be heavy enough to significantly affect running on the following days.

Saturday will be cloudy and cooler than Thursday, with qualifying running in the teens. A potential maximum temperature of 19C is only two or three degrees cooler than 2019’s session, but those are the margins that matter in F1, in terms of getting the softest compound tyres working for a street circuit Track temperatures are therefore likely to reach around 40C

Race day won’t have full cloud cover but intermittent, chasing clouds which could mean sudden track cooling during the grand prix. The air temperature will be significantly cooler than 2019, not going above 20C where the last grand prix in Monte Carlo was in the mid-20s. The risk of rain will remain low, however and wind speeds – not a huge concern in Monaco’s enclosed track – will be relatively low.

  1. Potentially good for Mercedes?

    1. Yes, but the soft C5 will negate it mostly so the car with the best mechanical grip is here in advantage.

      Red Bull is good on the soft but it hurts the rears more then of that of Mercedes. But if Max get in front of Lewis i don’t think Lewis can pass even on new tyres.

      1. That’s true. It’s going to be a one stop no matter what, so its about getting temperatures for qualifying.

      You’d think so usually, but Bottas usually takes a while to get temps into the tyres and that might compromise him for quali (and therefore the race).

      Sadly yes – like Mercedes needs any more help to win yet again

    4. Call me crazy, but I don’t think cooler temperatures are good news for Mercedes. Their car is pretty easy on its tyres, which is why they were stronger in races than in qualifying in the first couple of race weekends. Cars that are easy on tyres, usually have more problems getting enough heat into the tyres over a single flying lap.
      Just because they were strong at tyre-warmup in the past, doesn’t automatically mean they still have that quality (remember, they don’t have DAS anymore).

  2. I wouldn’t consider the 19-21 (19 highest forecasted for tomorrow, 20 for QLF, and 21 for race day) range cool.
    Pleasantly warm anyway.

    1. I’d call it decent weather and I’m a proverbial “frozen stick” who needs 25+ degrees.

      1. @esploratore Indeed. Any T-shirt/short weather is good.

  3. There might also be some rain on Saturday morning, which could make it interesting for FP3 (drivers potentially crashing) and maybe even for qualifying.
