Event: mostly fire pokemon

Is your biome more likely to spawn fire types? If so that is why. I am desert so its like 70/30% spread for me, except piloswine who spawns here anyway.

I'm seeing a lot of swinubs and shellders. Also caught a Lapras and a Sneasel. Probably 70/30 for me.

Slugmas the most here, but probably just nest spawns.

Followed by Swinubs and Growlithes.

Then Shellders, Seels and Cyndaquils.

Houndours and Charmanders are also seen here, still no Laprases, though.

Sneasels, saw some in the nearby screen, but couldn't reach them.

I’m glad it’s working out this way, I encounter basically 0 fire types in the wild and a lot of ice. Maybe they’re doing something different instead of just increasing the spawn rates of the types? The increase may be base of how unlikely you would encounter the type in your area. If you normally see a lot of ice the increase is not as dramatic while the type you do not see often is increase a lot.

Ponyta out the wazoo! Followed by Growlithe, Vulpix, and even Houndour. I haven't seen an ice type yet!

Yes I've seen a significant increase in fire pokemon that are normally quite uncommon here, but absolutely no increase in ice types (some of which are normally pretty common here). For example I've seen way less Swinub here since the event started.

I'm getting about half and half. Grass/water biome here.

In my grass/water biome, fire types are normally uncommon and ice types almost unheard of.

Today, Vulpix, Charmander and Swinub have been spawning like Magikarps. Yet to see a Jynx or Lapras and only found one Seel, but somehow managed enough Shellders to (with Pinaps) have enough candies to evolve another hatched wonder (will hold off until the gym rework though).

Mainly water here usually with loads of swinubs.

But actually less now, cloysters are slightly more common though. But we are drowning in fire now.

I wonder if the hemisphere has anything to do with it? I'm north, it's a hot summer, and seeing a lot more fire (fortunately no slugma!) and only a slight uptick in ice (seel, shelder and few swinub, which are uncommon but not rare pre-event).
Can anyone in Southern winter confirm if they're getting a lot more ice then fire?

Around where I am, Swinub and Sneasel are normally fairly common (and were insanely common right after gen2, now just moderately common), as is shellder.

This event has not resulted in any apparent change in swinub abundance, nor shellders. Same looks to be true for sneasels. Slight increase in Seels, and I saw a Lap on nearby. On the other hand, it's fire every where I look - Cydnas (which I had previously only gotten 10 candies of since gen2 launch, now I have 29 without going pokemon hunting yet, just snagging them on my way to work), growlithes, and houndours are EVERYWHERE. Vulpix is common. None of these spawn naturally here outside of nests aside from a few unicorn spawns that occasionally drop growlithes.

So the question is - if your biome is normally fire, what are your spawns like?

It would be very generous of Niantic if they made the event spawn more of the stuff you don't normally see, so people who normally got fire saw lots of ice and people who normally got ice saw lots of fire. Or the event is just "FIRE!!! oh, and uh some ice" instead of "Fire and Ice".

My biome, which is usually grass water is pretty much split down the middle. Maybe like 60/40 fire/ice, but close to even.

I think proportionately they are about the same. Because I have seen over the course of 30 min

3 Swinub

4 Shellder

2 Growlithe

1 Vulpix

1 Seal

3 Cyndaquil

2 Charmander

I think the problem is that there are just more Fire types than Ice types.

I've played for about 2½ hours today and saw a ton of firemons, but not very many icemons. Infact, I've seen a few Swinubs, a few Shellders, one or two Seals, one Sneasel and that's it. Nothing else. On the other hand I have been drowning in Growlithe, Vulpix, Charmander and Ponyta with quite a few very welcome Cyndaquil thrown in. Only very few Houndour, but I just need a few more for Houndoom so that is OK. Haven't seen a single Slugma which is fine by me.

well it is what we get when niantic decides an event involving ice types when their bare between gens 1 and 2.
